Each film coated tablet contains Lopinavir USP 200mg and ritonavir USP 50mg.

Lopinavir and Ritonavir Tablets USP 200mg/50mg: Yellow film coated ovaloid tablets debossed with 'H' on one side and '70' on other side.

Lopinavir and Ritonavir Tablets is indicated in combination with other antiretroviral medicinal products for the treatment of human immunodeficiency virus (HIV-1) infected adults, adolescents and children above the age of 2 years. 

The choice of Lopinavir and Ritonavir Tablets to treat protease inhibitor experienced HIV-1 infected patients should be based on individual viral resistance testing and treatment history of patients (see sections 4.4 and 5.1).


Lopinavir and Ritonavir Tablets should be prescribed by physicians who are experienced in the treatment of HIV infection.

Lopinavir and Ritonavir Tablets must be swallowed whole and not chewed, broken or crushed

Posology 

Adults and adolescents 

The standard recommended dosage of Lopinavir and Ritonavir Tablets is 400/100 mg (two 200/50 mg) tablets twice daily taken with or without food. In adult patients, in cases where oncedaily dosing is considered necessary for the management of the patient, Lopinavir and Ritonavir Tablets may be administered as 800/200 mg (four 200/50 mg tablets) once daily with or without food. The use of a once-daily dosing should be limited to those adult patients having only very few protease inhibitor (PI) associated mutations (i.e. less than 3 PI mutations in line with clinical trial results, see section 5.1 for the full description of the population) and should take into account the risk of a lesser sustainability of the virologic suppression (see section 5.1) and higher risk of diarrhoea (see section 4.8) compared to the recommended standard twice-daily dosing. An oral solution is available to patients who have difficulty swallowing. Refer to the Summary of Product Characteristics for Lopinavir and Ritonavir Tablets oral solution for dosing instructions.

Paediatric population (2 years of age and above) 

The adult dose of Lopinavir and Ritonavir Tablets (400/100 mg twice daily) may be used in children 40 kg or greater or with a Body Surface Area (BSA)* greater than 1.4 m2. For children weighing less than 40 kg or with a BSA between 0.5 and 1.4 m2 and able to swallow tablets, please refer to the Lopinavir and Ritonavir Tablets 100 mg/25 mg tablets Summary of Product Characteristics. For children unable to swallow tablets, please refer to the Lopinavir and Ritonavir Tablets oral solution Summary of Product Characteristics. Based on the current data available, Lopinavir and Ritonavir Tablets should not be administered once daily in paediatric patients (see section 5.1).

* Body surface area can be calculated with the following equation:

BSA (m2) = √ (Height (cm) X Weight (kg) / 3600)

Children less than 2 years of age 

The safety and efficacy of Lopinavir and Ritonavir Tablets in children aged less than 2 years have not yet been established. Currently available data are described in section 5.2 but no recommendation on a posology can be made. 

Concomitant Therapy: Efavirenz or nevirapine 

The following table contains dosing guidelines for Lopinavir and Ritonavir Tablets based on BSA when used in combination with Efavirenz or nevirapine in children.

Hepatic impairment 

In HIV-infected patients with mild to moderate hepatic impairment, an increase of approximately 30% in Lopinavir exposure has been observed but is not expected to be of clinical relevance (see section 5.2). No data are available in patients with severe hepatic impairment. Lopinavir and Ritonavir Tablets must not be given to these patients (see section 4.3).

Renal impairment 

Since the renal clearance of Lopinavir and ritonavir is negligible, increased plasma concentrations are not expected in patients with renal impairment. Because Lopinavir and ritonavir are highly protein bound, it is unlikely that they will be significantly removed by haemodialysis or peritoneal dialysis. 

Pregnancy and postpartum 

•  No dose adjustment is required for Lopinavir/ritonavir during pregnancy and postpartum.

•  Once-daily administration of Lopinavir/ritonavir is not recommended for pregnant women due to the lack of pharmacokinetic and clinical data.

Method of administration  

Lopinavir and Ritonavir Tablets are administered orally and must be swallowed whole and not chewed, broken or crushed. Lopinavir and Ritonavir Tablets can be taken with or without food


Hypersensitivity to the active substances or to any of the excipients. Severe hepatic insufficiency. Lopinavir and Ritonavir Tablets contains Lopinavir and ritonavir, both of which are inhibitors of the P450 isoform CYP3A. Lopinavir and Ritonavir Tablets should not be co-administered with medicinal products that are highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious and/or life threatening events. These medicinal products include Medicinal product class Medicinal products within class Rationale Concomitant medicinal product levels increased Alpha1-adrenoreceptor antagonist Alfuzosin Increased plasma concentrations of alfuzosin which may lead to severe hypotension. The concomitant administration with alfuzosin is contraindicated (see section 4.5). Antianginal Ranolazine Increased plasma concentrations of ranolazine which may increase the potential for serious and/or life-threatening reactions (see section 4.5). Antiarrhythmics Amiodarone, dronedarone Increased plasma concentrations of amiodarone and dronedarone. Thereby, increasing the risk of arrhythmias or other serious adverse reactions (see section 4.5). Antibiotic Fusidic Acid Increased plasma concentrations of fusidic acid. The concomitant administration with fusidic acid is contraindicated in dermatological infections (see section 4.5). Anticancer Venetoclax Increased plasma concentrations of venetoclax.

See section 4.4 and section 4.5 for coadministration of sildenafil in patients with erectile dysfunction. Vardenafil Increased plasma concentrations of vardenafil (see sections 4.4 and 4.5) Sedatives/hypnotics Oral midazolam, triazolam Increased plasma concentrations of oral midazolam and triazolam. Thereby, increasing the risk of extreme sedation and respiratory depression from these agents. For caution on parenterally administered midazolam, see section 4.5. Lopinavir/ritonavir medicinal product level decreased Herbal products St. John's wort Herbal preparations containing St John's wort (Hypericum perforatum) due to the risk of decreased plasma concentrations and reduced clinical effects of lopinavir and ritonavir (see section 4.5).

with coexisting conditions 

Hepatic impairment: 

The safety and efficacy of Lopinavir and Ritonavir Tablets has not been established in patients with significant underlying liver disorders. Lopinavir and Ritonavir Tablets is contraindicated in patients with severe liver impairment (see section 4.3). Patients with chronic hepatitis B or C and treated with combination antiretroviral therapy are at an increased risk for severe and potentially fatal hepatic adverse reactions. In case of concomitant antiviral therapy for hepatitis B or C, please refer to the relevant product information for these medicinal products.

Patients with pre-existing liver dysfunction including chronic hepatitis have an increased frequency of liver function abnormalities during combination antiretroviral therapy and should be monitored according to standard practice. If there is evidence of worsening liver disease in such patients, interruption or discontinuation of treatment should be considered. 

Elevated transaminases with or without elevated bilirubin levels have been reported in HIV-1 mono-infected and in individuals treated for post-exposure prophylaxis as early as 7 days after the initiation of Lopinavir/ritonavir in conjunction with other antiretroviral agents. In some cases the hepatic dysfunction was serious.

Appropriate laboratory testing should be conducted prior to initiating therapy with Lopinavir/ritonavir and close monitoring should be performed during treatment.

Renal impairment 

Since the renal clearance of Lopinavir and ritonavir is negligible, increased plasma concentrations are not expected in patients with renal impairment. Because Lopinavir and ritonavir are highly protein bound, it is unlikely that they will be significantly removed by haemodialysis or peritoneal dialysis.

Hemophilia 

There have been reports of increased bleeding, including spontaneous skin haematomas and haemarthrosis in patients with haemophilia type A and B treated with protease inhibitors. In some patients additional factor VIII was given. In more than half of the reported cases, treatment with protease inhibitors was continued or reintroduced if treatment had been discontinued. A causal relationship had been evoked, although the mechanism of action had not been elucidated.

Haemophiliac patients should therefore be made aware of the possibility of increased bleeding.

Pancreatitis 

Cases of pancreatitis have been reported in patients receiving Lopinavir and Ritonavir Tablets, including those who developed hypertriglyceridaemia. In most of these cases patients have had a prior history of pancreatitis and/or concurrent therapy with other medicinal products associated with pancreatitis. Marked triglyceride elevation is a risk factor for development of pancreatitis. Patients with advanced HIV disease may be at risk of elevated triglycerides and pancreatitis

Pancreatitis should be considered if clinical symptoms (nausea, vomiting, abdominal pain) or abnormalities in laboratory values (such as increased serum lipase or amylase values) suggestive of pancreatitis should occur. Patients who exhibit these signs or symptoms should be evaluated and Lopinavir and Ritonavir Tablets therapy should be suspended if a diagnosis of pancreatitis is made (see section 4.8). 

Immune Reconstitution Inflammatory Syndrome 

In HIV-infected patients with severe immune deficiency at the time of institution of combination antiretroviral therapy (CART), an inflammatory reaction to asymtomatic or residual opportunistic pathogens may arise and cause serious clinical conditions, or aggravation of symptoms. Typically, such reactions have been observed within the first few weeks or months of initiation of CART. Relevant examples are cytomegalovirus retinitis, generalised and/or focal mycobacterial infections, and Pneumocystis jiroveci pneumonia. Any inflammatory symptoms should be evaluated and treatment instituted when necessary.

Autoimmune disorders (such as Graves' disease) have also been reported to occur in the setting of immune reconstitution; however, the reported time to onset is more variable and can occur many months after initiation of treatment.

Osteonecrosis 

Although the etiology is considered to be multifactorial (including corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index), cases of osteonecrosis have been reported particularly in patients with advanced HIV-disease and/or long-term exposure to combination antiretroviral therapy (CART). Patients should be advised to seek medical advice if they experience joint aches and pain, joint stiffness or difficulty in movement.

PR interval prolongation 

Lopinavir/ritonavir has been shown to cause modest asymptomatic prolongation of the PR interval in some healthy adult subjects. Rare reports of 2nd or 3rd degree atroventricular block in patients with underlying structural heart disease and pre-existing conduction system abnormalities or in patients receiving drugs known to prolong the PR interval (such as verapamil or atazanavir) have been reported in patients receiving lopinavir/ritonavir. Lopinavir and Ritonavir Tablets should be used with caution in such patients (see section 5.1).

Weight and metabolic parameters 

An increase in weight and in levels of blood lipids and glucose may occur during antiretroviral therapy. Such changes may in part be linked to disease control and life style. For lipids, there is in some cases evidence for a treatment effect, while for weight gain there is no strong evidence relating this to any particular treatment. For monitoring of blood lipids and glucose, reference is made to established HIV treatment guidelines. Lipid disorders should be managed as clinically appropriate.

Interactions with medicinal products 

Lopinavir and Ritonavir Tablets contains Lopinavir and ritonavir, both of which are inhibitors of the P450 isoform CYP3A. Lopinavir and Ritonavir Tablets is likely to increase plasma concentrations of medicinal products that are primarily metabolised by CYP3A. These increases of plasma concentrations of co-administered medicinal products could increase or prolong their therapeutic effect and adverse events (see sections 4.3 and 4.5).

Strong CYP3A4 inhibitors such as protease inhibitors may increase bedaquiline exposure which could potentially increase the risk of bedaquiline-related adverse reactions. Therefore, combination of bedaquiline with Lopinavir/ritonavir should be avoided. However, if the benefit outweighs the risk, co-administration of bedaquiline with Lopinavir/ritonavir must be done with caution. More frequent electrocardiogram monitoring and monitoring of transaminases is recommended (see section 4.5 and refer to the bedaquiline SmPC).

Co-administration of delamanid with a strong inhibitor of CYP3A (as lopinavir/ritonavir) may increase exposure to delamanid metabolite, which has been associated with QTc prolongation. Therefore, if co-administration of delamanid with lopinavir/ritonavir is considered necessary, very frequent ECG monitoring throughout the full delamanid treatment period is recommended (see section 4.5 and refer to the delamanid SmPC).

Life-threatening and fatal drug interactions have been reported in patients treated with colchicine and strong inhibitors of CYP3A like ritonavir. Concomitant administration with colchicine is contraindicated in patients with renal and/or hepatic impairment (see sections 4.3 and 4.5).

The combination of Lopinavir and Ritonavir Tablets with: 

-   Tadalafil, indicated for the treatment of pulmonary arterial hypertension, is not recommended (see section 4.5); 

-   riociguat is not recommended (see section 4.5);

-   vorapaxar is not recommended (see section 4.5);

-   fusidic acid in osteo-articular infections is not recommended (see section 4.5);

-   salmeterol is not recommended (see section 4.5);

-   rivaroxaban is not recommended (see section 4.5).

The combination of Lopinavir and Ritonavir Tablets with atorvastatin is not recommended. If the use of atorvastatin is considered strictly necessary, the lowest possible dose of atorvastatin should be administered with careful safety monitoring. Caution must also be exercised and reduced doses should be considered if Lopinavir and Ritonavir Tablets is used concurrently with rosuvastatin. If treatment with a HMG-CoA reductase inhibitor is indicated, pravastatin or fluvastatin is recommended (see section 4.5).

PDE5 inhibitors 

Particular caution should be used when prescribing sildenafil or Tadalafil for the treatment of erectile dysfunction in patients receiving Lopinavir and Ritonavir Tablets. Co-administration of Lopinavir and Ritonavir Tablets with these medicinal products is expected to substantially increase their concentrations and may result in associated adverse events such as hypotension, syncope, visual changes and prolonged erection (see section 4.5). Concomitant use of avanafil or vardenafil and lopinavir/ritonavir is contraindicated (see section 4.3). Concomitant use of sildenafil prescribed for the treatment of pulmonary arterial hypertension with Lopinavir and Ritonavir Tablets is contraindicated (see section 4.3).

Particular caution must be used when prescribing Lopinavir and Ritonavir Tablets and medicinal products known to induce QT interval prolongation such as: chlorpheniramine, quinidine, erythromycin, clarithromycin. Indeed, Lopinavir and Ritonavir Tablets could increase concentrations of the co-administered medicinal products and this may result in an increase of their associated cardiac adverse reactions. Cardiac events have been reported with Lopinavir and Ritonavir Tablets in preclinical studies; therefore, the potential cardiac effects of Lopinavir and Ritonavir Tablets cannot be currently ruled out (see sections 4.8 and 5.3).

Co-administration of Lopinavir and Ritonavir Tablets with rifampicin is not recommended. Rifampicin in combination with Lopinavir and Ritonavir Tablets causes large decreases in lopinavir concentrations which may in turn significantly decrease the lopinavir therapeutic effect. Adequate exposure to lopinavir/ritonavir may be achieved when a higher dose of Lopinavir and Ritonavir Tablets is used but this is associated with a higher risk of liver and gastrointestinal toxicity. Therefore, this co-administration should be avoided unless judged strictly necessary (see section 4.5).

Concomitant use of Lopinavir and Ritonavir Tablets and fluticasone or other glucocorticoids that are metabolised by CYP3A4, such as budesonide and triamcinolone, is not recommended unless the potential benefit of treatment outweighs the risk of systemic corticosteroid effects, including Cushing's syndrome and adrenal suppression (see section 4.5).

Other 

Lopinavir and Ritonavir Tablets is not a cure for HIV infection or AIDS. While effective viral suppression with antiretroviral therapy has been proven to substantially reduce the risk of sexual transmission, a residual risk cannot be excluded. Precautions to prevent transmission should be taken in accordance with national guidelines. People taking Lopinavir and Ritonavir Tablets may still develop infections or other illnesses associated with HIV disease and AIDS


Lopinavir and Ritonavir Tablets contains lopinavir and ritonavir, both of which are inhibitors of the P450 isoform CYP3A in vitro. Co-administration of Lopinavir and Ritonavir Tablets and medicinal products primarily metabolised by CYP3A may result in increased plasma concentrations of the other medicinal product, which could increase or prolong its therapeutic and adverse reactions. Lopinavir and Ritonavir Tablets does not inhibit CYP2D6, CYP2C9, CYP2C19, CYP2E1, CYP2B6 or CYP1A2 at clinically relevant concentrations (see section 4.3).

Lopinavir and Ritonavir Tablets has been shown in vivo to induce its own metabolism and to increase the biotransformation of some medicinal products metabolised by cytochrome P450 enzymes (including CYP2C9 and CYP2C19) and by glucuronidation. This may result in lowered plasma concentrations and potential decrease of efficacy of co-administered medicinal products.

Medicinal products that are contraindicated specifically due to the expected magnitude of interaction and potential for serious adverse events are listed in section 4.3.

All interaction studies, when otherwise not stated, were performed using Lopinavir and Ritonavir Tablets capsules, which gives an approximately 20% lower exposure of lopinavir than the 200/50 mg tablets.

Known and theoretical interactions with selected antiretrovirals and non-antiretroviral medicinal products are listed in the table below.

increase.

Concomitant administration of

Lopinavir and Ritonavir Tablets and alfuzosin is contra-indicated (see section 4.3) as alfuzosin-related toxicity, including hypotension,

may be increased.

Analgesics 

Fentanyl

Fentanyl:

Increased risk of side-effects

(respiratory depression, sedation) due to higher plasma concentrations because of CYP3A4 inhibition by

lopinavir/ritonavir.

Careful monitoring of adverse effects (notably respiratory

depression but also sedation) is recommended when fentanyl is

concomitantly administered with Lopinavir and Ritonavir Tablets.

Antianginal 

Ranolazine

Due to CYP3A inhibition by lopinavir/ritonavir, concentrations of ranolazine are expected to

increase.

The concomitant administration of

Lopinavir and Ritonavir Tablets and ranolazine is contraindicated (see

section 4.3).

Antiarrhythmics

contraindicated (see section 4.3) as the risk of arrhythmias or other

serious adverse reactions may be

increased.

Digoxin

Digoxin:

Plasma concentrations may be increased due to P-glycoprotein

inhibition by lopinavir/ritonavir.

The increased digoxin level may lessen over time as Pgp induction

develops.

Caution is warranted and therapeutic drug monitoring of

digoxin concentrations, if available, is recommended in case of co-

administration of Lopinavir and Ritonavir Tablets and digoxin.

Particular caution should be used when prescribing Lopinavir and

Ritonavir Tablets in patients taking digoxin as the acute inhibitory effect of ritonavir on Pgp is

expected to significantly increase

digoxin levels. Initiation of digoxin

in patients already taking Lopinavir

and Ritonavir Tablets is likely to result in lower than expected

increases of digoxin concentrations.

Bepridil, Systemic Lidocaine,

and Quinidine

Bepridil, Systemic Lidocaine, Quinidine:

Concentrations may be increased when co-administered with lopinavir/ritonavir.

Caution is warranted and therapeutic drug concentration

Antibiotics 

Clarithromycin

Clarithromycin:

Moderate increases in clarithromycin AUC are expected due to CYP3A inhibition by lopinavir/ritonavir.

For patients with renal impairment

(CrCL < 30 ml/min) dose reduction of clarithromycin should be

considered (see section 4.4).

Caution should be exercised in administering clarithromycin with

Lopinavir and Ritonavir Tablets to patients with impaired hepatic or

renal function.

Anticancer agents 

Afatinib

(Ritonavir 200 mg twice daily)

Afatinib:

AUC: ↑

Cmax: ↑

The extent of increase depends on the timing of ritonavir administration.

Caution should be exercised in administering afatinib with

Lopinavir and Ritonavir Tablets.

Refer to the afatinib SmPC for dosage adjustment

recommendations. Monitor for ADRs related to afatinib.

Ceritinib

Serum concentrations may be increased due to CYP3A and P-gp inhibition by lopinavir/ritonavir.

Caution should be exercised in administering ceritinib with

Lopinavir and Ritonavir Tablets.

Refer to the ceritinib SmPC for dosage adjustment

recommendations. Monitor for

 

 

 

ADRs related to ceritinib.

Most tyrosine kinase inhibitors such as dasatinib and nilotinib, vincristine, vinblastine

Most tyrosine kinase inhibitors such as dasatinib and nilotinib, also vincristine and vinblastine:

Risk of increased adverse events due to higher serum concentrations because of CYP3A4 inhibition by

lopinavir/ritonavir.

Careful monitoring of the tolerance of these anticancer agents.

Ibrutinib

Serum concentrations may be increased due to CYP3A inhibition

by lopinavir/ritonavir.

Co-administration of ibrutinib and Lopinavir and Ritonavir Tablets may increase ibrutinib exposure which may increase the risk of

toxicity including risk of tumor

lysis syndrome. Co-administration of ibrutinib and Lopinavir and

Ritonavir Tablets should be avoided. If the benefit is considered to outweigh the risk and Lopinavir

and Ritonavir Tablets must be used,

reduce the ibrutinib dose to 140 mg and monitor patient closely for

toxicity.

Venetoclax

Due to CYP3A inhibition by lopinavir/ritonavir.

Serum concentrations may be increased due to CYP3A inhibition

by lopinavir/ritonavir, resulting in increased risk of tumor lysis syndrome at the dose initiation and

 

 

 

during the ramp-up phase (see section 4.3 and refer to the venetoclax SmPC).

For patients who have completed the ramp-up phase and are on a

steady daily dose of venetoclax,

reduce the venetoclax dose by at

least 75% when used with strong

CYP3A inhibitors (refer to the venetoclax SmPC for dosing

instructions). Patients should be

closely monitored for signs related to venetoclax toxicities.

Anticoagulants 

Warfarin

Warfarin:

Concentrations may be affected when co-administered with lopinavir/ritonavir due to CYP2C9

induction.

It is recommended that INR

(international normalised ratio) be

monitored.

Rivaroxaban

may increase rivaroxaban exposure which may increase the risk of

bleeding.

The use of rivaroxaban is not recommended in patients receiving concomitant treatment with

 

 

 

Lopinavir and Ritonavir Tablets (see section 4.4).

Vorapaxar

Serum concentrations may be increased due to CYP3A inhibition

by lopinavir/ritonavir.

The co-administration of vorapaxar with Lopinavir and Ritonavir

Tablets is not recommended (see section 4.4 and refer to the vorapaxar SmPC).

Anticonvulsants 

Phenytoin

Phenytoin:

Steady-state concentrations was moderately decreased due to

CYP2C9 and CYP2C19 induction

by lopinavir/ritonavir.

Lopinavir:

Concentrations are decreased due to CYP3A induction by phenytoin.

Caution should be exercised in administering phenytoin with

Lopinavir and Ritonavir Tablets.

Phenytoin levels should be monitored when co-administering with Lopinavir and Ritonavir Tablets.

When co-administered with phenytoin, an increase of Lopinavir and Ritonavir Tablets dosage may

be envisaged. Dose adjustment has not been evaluated in clinical

practice.

Lopinavir and Ritonavir Tablets must not be administered once daily in combination with phenytoin.

Carbamazepine and

Phenobarbital

Carbamazepine:

Serum concentrations may be increased due to CYP3A inhibition

Caution should be exercised in administering carbamazepine or phenobarbital with Lopinavir and

 

 

by lopinavir/ritonavir.

Lopinavir:

Concentrations may be decreased due to CYP3A induction by carbamazepine and phenobarbital.

Ritonavir Tablets.

Carbamazepine and phenobarbital levels should be monitored when co-administering with Lopinavir and Ritonavir Tablets.

When co-administered with carbamazepine or phenobarbital, an increase of Lopinavir and Ritonavir Tablets dosage may be envisaged.

Dose adjustment has not been evaluated in clinical practice.

Lopinavir and Ritonavir Tablets must not be administered once daily in combination with carbamazepine

and phenobarbital.

Lamotrigine and Valproate

Lamotrigine:

AUC: ↓ 50%

Cmax: ↓ 46%

Cmin: ↓ 56%

Due to induction of lamotrigine

glucuronidation

Valproate: ↓

Patients should be monitored closely for a decreased VPA effect when Lopinavir and Ritonavir

Tablets and valproic acid or valproate are given concomitantly.

In patients starting or stopping

Lopinavir and Ritonavir Tablets while currently taking maintenance

dose of lamotrigine:

lamotrigine dose may need to be

increased if Lopinavir and Ritonavir

Tablets is added, or decreased if

Lopinavir and Ritonavir Tablets is

 

 

 

discontinued; therefore plasma

lamotrigine monitoring should be

conducted, particularly before and during 2 weeks after starting or

stopping Lopinavir and Ritonavir

Tablets, in order to see if lamotrigine dose adjustment is

needed.

In patients currently taking

Lopinavir and Ritonavir Tablets and starting lamotrigine: no dose

adjustments to the recommended dose escalation of lamotrigine should be necessary.

Antidepressants and Anxiolytics 

Trazodone single dose (Ritonavir, 200 mg BID)

Trazodone:

AUC: ↑ 2.4-fold

Adverse events of nausea, dizziness, hypotension and syncope were observed following co-

administration of trazodone and

ritonavir.

It is unknown whether the combination of Lopinavir and

Ritonavir Tablets causes a similar increase in trazodone exposure. The

combination should be used with caution and a lower dose of trazodone should be considered.

Antifungals 

Ketoconazole and Itraconazole

Ketoconazole, Itraconazole: Serum concentrations may be increased due to CYP3A inhibition by lopinavir/ritonavir.

High doses of ketoconazole and itraconazole (> 200 mg/day) are not

recommended.

 

Voriconazole

Voriconazole:

Concentrations may be decreased.

Co-administration of voriconazole and low dose ritonavir (100 mg

BID) as contained in Lopinavir and

Ritonavir Tablets should be avoided unless an assessment of the

benefit/risk to patient justifies the

use of voriconazole.

Anti-gout agents 

Colchicine single dose (Ritonavir 200 mg twice-daily)

Colchicine:

AUC: ↑ 3-fold

Cmax: ↑ 1.8-fold

Due to P-gp and/or CYP3A4 inhibition by ritonavir.

Concomitant administration of

Lopinavir and Ritonavir Tablets with colchicine in patients with

renal and/or hepatic impairment is

contraindicated due to a potential increase of colchicine-related

serious and/or life-threatening

reactions such as neuromuscular

toxicity (including rhabdomyolysis)

(see sections 4.3 and 4.4). A reduction in colchicine dosage or an

interruption of colchicine treatment is recommended in patients with

normal renal or hepatic function if treatment with Lopinavir and

Ritonavir Tablets is required. Refer to colchicine prescribing information.

Antihistamines 

 

Astemizole Terfenadine

Serum concentrations may be increased due to CYP3A inhibition

by lopinavir/ritonavir.

Concomitant administration of

Lopinavir and Ritonavir Tablets and astemizole and terfenadine is

contraindicated as it may increase

the risk of serious arrhythmias from these agents (see section 4.3).

Anti-infectives 

Fusidic acid

Fusidic acid:

Concentrations may be increased due to CYP3A inhibition by lopinavir/ritonavir.

Concomitant administration of

Lopinavir and Ritonavir Tablets with fusidic acid is contra-indicated

in dermatological indications due to

the increased risk of adverse events related to fusidic acid, notably

rhabdomyolysis (see section 4.3).

When used for osteo-articular infections, where the co-

administration is unavoidable, close clinical monitoring for muscular adverse events is strongly recommended (see section 4.4).

Antimycobacterials 

Bedaquiline

(single dose)

(Lopinavir/ritonavir 400/100 mg

BID, multiple dose)

Bedaquiline:

AUC: ↑ 22%

Cmax: ↔

A more pronounced effect on bedaquiline plasma exposures may be observed during prolonged co-

CYP3A4 inhibition likely due to

lopinavir/ritonavir.

administration of bedaquiline with

Lopinavir and Ritonavir Tablets must be done with caution. More frequent electrocardiogram

monitoring and monitoring of

transaminases is recommended (see section 4.4 and refer to the bedaquiline SmPC).

Delamanid (100 mg BID)

(Lopinavir/ritonavir 400/100 mg

BID)

Delamanid:

AUC: ↑ 22%

DM-6705 (delamanid active

metabolite):

AUC: ↑ 30%

A more pronounced effect on DM-

6705 exposure may be observed during prolonged co-administration with lopinavir/ritonavir.

Due to the risk of QTc prolongation associated with DM-6705, if co-

administration of delamanid with

Lopinavir and Ritonavir Tablets is considered necessary, very frequent

ECG monitoring throughout the full delamanid treatment period is

recommended (see section 4.4 and refer to the delamanid SmPC).

Rifabutin, 150 mg QD

Rifabutin (parent drug and active 25-O-desacetyl metabolite):

AUC: ↑ 5.7-fold

Cmax: ↑ 3.5-fold

When given with Lopinavir and

Ritonavir Tablets the recommended dose of rifabutin is 150 mg 3 times per week on set days (for example Monday-Wednesday-Friday).

Increased monitoring for rifabutinassociated adverse reactions

including neutropenia and uveitis is warranted due to an expected

increase in exposure to rifabutin.

Further dosage reduction of

 

 

 

rifabutin to 150 mg twice weekly on set days is recommended for

patients in whom the 150 mg dose 3

times per week is not tolerated. It should be kept in mind that the

twice weekly dosage of 150 mg may not provide an optimal

exposure to rifabutin thus leading to

a risk of rifamycin resistance and a treatment failure. No dose

adjustment is needed for Lopinavir and Ritonavir Tablets.

Rifampicin

Lopinavir:

Large decreases in lopinavir concentrations may be observed due to CYP3A induction by rifampicin.

Co-administration of Lopinavir and

Ritonavir Tablets with rifampicin is not recommended as the decrease in

lopinavir concentrations may in turn significantly decrease the lopinavir therapeutic effect. A dose

adjustment of Lopinavir and

Ritonavir Tablets 400 mg/400 mg

(i.e. Lopinavir and Ritonavir

Tablets 400/100 mg + ritonavir 300 mg) twice daily has allowed

compensating for the CYP 3A4 inducer effect of rifampicin.

However, such a dose adjustment might be associated with ALT/AST elevations and with increase in

 

 

 

gastrointestinal disorders.

Therefore, this co-administration should be avoided unless judged strictly necessary. If this coadministration is judged

unavoidable, increased dose of

Lopinavir and Ritonavir Tablets at 400 mg/400 mg twice daily may be administered with rifampicin under

close safety and therapeutic drug monitoring. The Lopinavir and

Ritonavir Tablets dose should be titrated upward only after rifampicin has been initiated (see section 4.4).

Antipsychotics 

Lurasidone

Due to CYP3A inhibition by lopinavir/ritonavir, concentrations of lurasidone are expected to

increase.

The concomitant administration with lurasidone is contraindicated (see section 4.3).

Pimozide

Due to CYP3A inhibition by lopinavir/ritonavir, concentrations of pimozide are expected to

increase.

Concomitant administration of

Lopinavir and Ritonavir Tablets and pimozide is contraindicated as it

may increase the risk of serious

haematologic abnormalities or other serious adverse effects from this agent (see section 4.3)

Quetiapine

Due to CYP3A inhibition by

Concomitant administration of

 

 

lopinavir/ritonavir, concentrations of quetiapine are expected to

increase.

Lopinavir and Ritonavir Tablets and quetiapine is contraindicated as it may increase quetiapine-related

toxicity.

Benzodiazepines 

Midazolam

Oral Midazolam:

AUC: ↑ 13-fold

Parenteral Midazolam:

AUC: ↑ 4-fold

Due to CYP3A inhibition by lopinavir/ritonavir

Lopinavir and Ritonavir Tablets must not be co-administered with oral midazolam (see section 4.3), whereas caution should be used

with co-administration of Lopinavir

and Ritonavir Tablets and parenteral midazolam. If Lopinavir and

Ritonavir Tablets is co-administered with parenteral midazolam, it

should be done in an intensive care unit (ICU) or similar setting which

ensures close clinical monitoring and appropriate medical

management in case of respiratory depression and/or prolonged

sedation. Dosage adjustment for

midazolam should be considered

especially if more than a single dose of midazolam is administered.

Beta2-adrenoceptor agonist (long acting) 

Salmeterol

Salmeterol:

Concentrations are expected to

adverse events associated with salmeterol, including QT prolongation, palpitations and sinus

tachycardia. Therefore, concomitant administration of Lopinavir and Ritonavir Tablets with salmeterol is not recommended (see section 4.4).

Calcium channel blockers 

Felodipine, Nifedipine, and

Nicardipine

Felodipine, Nifedipine, Nicardipine:

Concentrations may be increased due to CYP3A inhibition by lopinavir/ritonavir.

Clinical monitoring of therapeutic and adverse effects is recommended when these medicines are

concomitantly administered with Lopinavir and Ritonavir Tablets.

Corticosteroids 

Dexamethasone

Lopinavir:

Concentrations may be decreased due to CYP3A induction by dexamethasone.

Clinical monitoring of antiviral efficacy is recommended when

these medicines are concomitantly administered with Lopinavir and Ritonavir Tablets.

Inhaled, injectable or intranasal fluticasone propionate, budesonide, triamcinolone

Fluticasone propionate, 50 µg intranasal 4 times daily:

Plasma concentrations ↑

Cortisol levels ↓ 86%

Greater effects may be expected when fluticasone propionate is

inhaled. Systemic corticosteroid effects including Cushing's

syndrome and adrenal suppression have been reported in patients receiving ritonavir and inhaled or

 

 

 

intranasally administered

fluticasone propionate; this could

also occur with other corticosteroids metabolised via the P450 3A pathway e.g. budesonide and

triamcinolone. Consequently,

concomitant administration of

Lopinavir and Ritonavir Tablets and these glucocorticoids is not

recommended unless the potential

benefit of treatment outweighs the risk of systemic corticosteroid

effects (see section 4.4). A dose reduction of the glucocorticoid

should be considered with close

monitoring of local and systemic effects or a switch to a

glucocorticoid, which is not a

substrate for CYP3A4 (e.g. beclomethasone). Moreover, in case of withdrawal of glucocorticoids progressive dose reduction may have to be performed over a longer

period.

administration of Lopinavir and

Ritonavir Tablets with sildenafil is contraindicated (see section 4.3).

Co-administration of Lopinavir and

Ritonavir Tablets with tadalafil is

not recommended.

For erectile dysfunction:

Particular caution must be used when prescribing sildenafil or tadalafil in patients receiving

Lopinavir and Ritonavir Tablets with increased monitoring for adverse events including

hypotension, syncope, visual changes and prolonged erection (see

section 4.4).

When co-administered with

Lopinavir and Ritonavir Tablets, sildenafil doses must not exceed 25 mg in 48 hours and tadalafil doses must not exceed 10 mg every 72

hours.

Concomitant administration of

Lopinavir and Ritonavir Tablets and ergot alkaloids are contraindicated as it may lead to acute ergot

toxicity, including vasospasm and ischaemia (see section 4.3).

GI motility agent

 

Cisapride

Serum concentrations may be increased due to CYP3A inhibition

by lopinavir/ritonavir.

Concomitant administration of

Herbal products 

St John's wort (Hypericum perforatum)

Lopinavir:

Concentrations may be reduced due to induction of CYP3A by the herbal preparation St John's wort.

Herbal preparations containing St

John's wort must not be combined with lopinavir and ritonavir. If a

patient is already taking St John's wort, stop St John's wort and if possible check viral levels.

Lopinavir and ritonavir levels may increase on stopping St John's wort.

The dose of Lopinavir and Ritonavir

Tablets may need adjusting. The inducing effect may persist for at least 2 weeks after cessation of

treatment with St John's wort (see section 4.3). Therefore, Lopinavir

and Ritonavir Tablets can be started safely 2 weeks after cessation of St John's wort.

 

Immunosuppressants 

Cyclosporin, Sirolimus (rapamycin), and Tacrolimus

Cyclosporin, Sirolimus

(rapamycin), Tacrolimus:

Concentrations may be increased due to CYP3A inhibition by lopinavir/ritonavir.

More frequent therapeutic concentration monitoring is

recommended until plasma levels of these products have been stabilised.

Lipid lowering agents 

Lovastatin and Simvastatin

Lovastatin, Simvastatin:

Markedly increased plasma concentrations due to CYP3A inhibition by lopinavir/ritonavir.

Since increased concentrations of

HMG-CoA reductase inhibitors may cause myopathy, including

rhabdomyolysis, the combination of these agents with Lopinavir and Ritonavir Tablets is contraindicated (see section 4.3).

Atorvastatin

Atorvastatin:

AUC: ↑ 5.9-fold

Cmax: ↑ 4.7-fold

Due to CYP3A inhibition by lopinavir/ritonavir.

The combination of Lopinavir and

Ritonavir Tablets with atorvastatin is not recommended. If the use of atorvastatin is considered strictly

necessary, the lowest possible dose of atorvastatin should be

administered with careful safety monitoring (see section 4.4).

Rosuvastatin, 20 mg QD

Rosuvastatin:

AUC: ↑ 2-fold

Cmax: ↑ 5-fold

exceeding the recommended dosage, despite the observed

induction.

Thyroid hormone replacement therapy 

Levothyroxine

Post-marketing cases have been reported indicating a potential

interaction between ritonavir containing products and levothyroxine.

Thyroid stimulating hormone (TSH) should be monitored in patients

treated with levothyroxine at least

the first month after starting and/or ending lopinavir/ritonavir treatment.

Vasodilating agents 

Bosentan

Lopinavir - ritonavir:

Lopinavir/ritonavir plasma concentrations may decrease due to CYP3A4 induction by bosentan.

Bosentan:

AUC: ↑ 5-fold

Cmax: ↑ 6-fold

Initially, bosentan Cmin :↑ by approximately 48-fold.

Due to CYP3A4 inhibition by lopinavir/ritonavir.

Caution should be exercised in administering Lopinavir and

Ritonavir Tablets with bosentan.

When Lopinavir and Ritonavir

Tablets is administered concomitantly with bosentan, the

efficacy of the HIV therapy should

be monitored and patients should be closely observed for bosentan

toxicity, especially during the first week of co-administration.

Riociguat

Serum concentrations may be increased due to CYP3A and P-gp

The co-administration of riociguat with Lopinavir and Ritonavir

 

inhibition by lopinavir/ritonavir.

Tablets is not recommended (see section 4.4 and refer to riociguat SmPC).

Other medicinal products 

Based on known metabolic profiles, clinically significant interactions are not expected between Lopinavir and Ritonavir Tablets and dapsone, trimethoprim/sulfamethoxazole, azithromycin or fluconazole.

 


Pregnancy 

As a general rule, when deciding to use antiretroviral agents for the treatment of HIV infection in pregnant women and consequently for reducing the risk of HIV vertical transmission to the newborn, the animal data as well as the clinical experience in pregnant women should be taken into account in order to characterize the safety for the foetus.

Lopinavir/ritonavir has been evaluated in over 3000 women during pregnancy, including over 1000 during the first trimester.

In post-marketing surveillance through the Antiretroviral Pregnancy Registry, established since January 1989, an increased risk of birth defects exposures with Lopinavir and Ritonavir Tablets has not been reported among over 1000 women exposed during the first trimester. The prevalence of birth defects after any trimester exposure to lopinavir is comparable to the prevalence observed in the general population. No pattern of birth defects suggestive of a common etiology was seen. Studies in animals have shown reproductive toxicity (see section 5.3). Based on the data mentioned, the malformative risk is unlikely in humans. Lopinavir can be used during pregnancy if clinically needed.

Breastfeeding 

Studies in rats revealed that lopinavir is excreted in the milk. It is not known whether this medicinal product is excreted in human milk. As a general rule, it is recommended that mothers infected by HIV do not breastfeed their babies under any circumstances in order to avoid transmission of HIV. 

Fertility 

Animal studies have shown no effects on fertility. No human data on the effect of lopinavir/ritonavir on fertility are available


No studies on the effects on the ability to drive and use machines have been performed. Patients should be informed that nausea has been reported during treatment with Lopinavir and Ritonavir Tablets (see section 4.8).


a. Summary of the safety profile 

The safety of Lopinavir and Ritonavir Tablets has been investigated in over 2600 patients in Phase II-IV clinical trials, of which over 700 have received a dose of 800/200 mg (6 capsules or 4 tablets) once daily. Along with nucleoside reverse transcriptase inhibitors (NRTIs), in some studies, Lopinavir and Ritonavir Tablets was used in combination with Efavirenz or nevirapine.

The most common adverse reactions related to Lopinavir and Ritonavir Tablets therapy during clinical trials were diarrhoea, nausea, vomiting, hypertriglyceridaemia and hypercholesterolemia. The risk of diarrhoea may be greater with once-daily dosing of Lopinavir and Ritonavir Tablets. Diarrhoea, nausea and vomiting may occur at the beginning of the treatment while hypertriglyceridaemia and hypercholesterolemia may occur later. Treatment emergent adverse events led to premature study discontinuation for 7% of subjects from Phase II-IV studies.

It is important to note that cases of pancreatitis have been reported in patients receiving Lopinavir and Ritonavir Tablets, including those who developed hypertriglyceridaemia. Furthermore, rare increases in PR interval have been reported during Lopinavir and Ritonavir Tablets therapy (see section 4.4).

b. Tabulated list of adverse reactions 

Adverse reactions from clinical trials and post-marketing experience in adult and paediatric patients: 

The following events have been identified as adverse reactions. The frequency category includes all reported events of moderate to severe intensity, regardless of the individual causality assessment. The adverse reactions are displayed by system organ class. Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1000 to < 1/100) and not known (cannot be estimated from the available data).

Events noted as having frequency “Not known” were identified via post-marketing surveillance.

c. Description of selected adverse reactions 

Cushing's syndrome has been reported in patients receiving ritonavir and inhaled or intranasally administered fluticasone propionate; this could also occur with other corticosteroids metabolised via the P450 3A pathway e.g. budesonide (see section 4.4 and 4.5).

Increased creatine phosphokinase (CPK), myalgia, myositis, and rarely, rhabdomyolysis have been reported with protease inhibitors, particularly in combination with nucleoside reverse transcriptase inhibitors. Metabolic parameters 

Weight and levels of blood lipids and glucose may increase during antiretroviral therapy (see section 4.4).

In HIV-infected patients with severe immune deficiency at the time of initiation of combination antiretroviral therapy (CART), an inflammatory reaction to asymptomatic or residual opportunistic infections may arise. Autoimmune disorders (such as Graves' disease) have also been reported; however, the reported time to onset is more variable and can occur many months after initiation of treatment (see section 4.4).

Cases of osteonecrosis have been reported, particularly in patients with generally acknowledged risk factors, advanced HIV disease or long-term exposure to combination antiretroviral therapy (CART). The frequency of this is unknown (see section 4.4).

d. Paediatric populations

To date, there is limited human experience of acute overdose with Lopinavir and Ritonavir Tablets.

The adverse clinical signs observed in dogs included salivation, emesis and diarrhoea/abnormal stool. The signs of toxicity observed in mice, rats or dogs included decreased activity, ataxia, emaciation, dehydration and tremors. 

There is no specific antidote for overdose with Lopinavir and Ritonavir Tablets. Treatment of overdose with Lopinavir and Ritonavir Tablets is to consist of general supportive measures including monitoring of vital signs and observation of the clinical status of the patient. If indicated, elimination of unabsorbed active substance is to be achieved by emesis or gastric lavage. Administration of activated charcoal may also be used to aid in removal of unabsorbed active substance. Since Lopinavir and Ritonavir Tablets is highly protein bound, dialysis is unlikely to be beneficial in significant removal of the active substance.


Pharmaco-therapeutic group: antivirals for systemic use, antivirals for treatment of HIV infections, combinations, ATC code: J05AR10 

Mechanism of action 

Lopinavir provides the antiviral activity of Lopinavir and Ritonavir Tablets. Lopinavir is an inhibitor of the HIV-1 and HIV-2 proteases. Inhibition of HIV protease prevents cleavage of the gag-pol poly protein resulting in the production of immature, non-infectious virus. 

Effects on the electrocardiogram 

QTcF interval was evaluated in a randomised, placebo and active (moxifloxacin 400 mg once daily) controlled crossover study in 39 healthy adults, with 10 measurements over 12 hours on Day 3. The maximum mean (95% upper confidence bound) differences in QTcF from placebo were 3.6 (6.3) and 13.1(15.8) for 400/100 mg twice daily and supratherapeutic 800/200 mg twice daily LPV/r, respectively. The induced QRS interval prolongation from 6 ms to 9.5 ms with high dose lopinavir/ritonavir (800/200 mg twice daily) contributes to QT prolongation. The two regimens resulted in exposures on Day 3 which were approximately 1.5 and 3-fold higher than those observed with recommended once-daily or twice-daily LPV/r doses at steady state. No subject experienced an increase in QTcF of ≥ 60 ms from baseline or a QTcF interval exceeding the potentially clinically relevant threshold of 500 ms.

Modest prolongation of the PR interval was also noted in subjects receiving lopinavir/ritonavir in the same study on Day 3. The mean changes from baseline in PR interval ranged from 11.6 ms to 24.4 ms in the 12 hour interval post dose. Maximum PR interval was 286 ms and no second or third degree heart block was observed (see section 4.4).

Antiviral activity in vitro  

The in vitro antiviral activity of lopinavir against laboratory and clinical HIV strains was evaluated in acutely infected lymphoblastic cell lines and peripheral blood lymphocytes, respectively. In the absence of human serum, the mean IC50 of lopinavir against five different HIV-1 laboratory strains was 19 nm. In the absence and presence of 50% human serum, the mean IC50 of lopinavir against HIV-1IIIB in MT4 cells was 17 nm and 102 n, respectively. In the absence of human serum, the mean IC50 of lopinavir was 6.5 nm against several HIV-1 clinical isolates.

Resistance 

In vitro selection of resistance 

HIV-1 isolates with reduced susceptibility to lopinavir have been selected in vitro. HIV-1 has been passaged in vitro with lopinavir alone and with lopinavir plus ritonavir at concentration ratios representing the range of plasma concentration ratios observed during Lopinavir and Ritonavir Tablets therapy. Genotypic and phenotypic analysis of viruses selected in these passages suggest that the presence of ritonavir, at these concentration ratios, does not measurably influence the selection of lopinavir-resistant viruses. Overall, the in vitro characterisation of phenotypic cross-resistance between lopinavir and other protease inhibitors suggest that decreased susceptibility to lopinavir correlated closely with decreased susceptibility to ritonavir and indinavir, but did not correlate closely with decreased susceptibility to amprenavir, saquinavir, and nelfinavir.

Analysis of resistance in ARV-naïve patients  

In clinical studies with a limited number of isolates analysed, the selection of resistance to lopinavir has not been observed in naïve patients without significant protease inhibitor resistance at baseline. See further the detailed description of the clinical studies.

Analysis of resistance in PI-experienced patients 

The selection of resistance to lopinavir in patients having failed prior protease inhibitor therapy was characterised by analysing the longitudinal isolates from 19 protease inhibitor-experienced subjects in 2 Phase II and one Phase III studies who either experienced incomplete virologic suppression or viral rebound subsequent to initial response to Lopinavir and Ritonavir Tablets and who demonstrated incremental in vitro resistance between baseline and rebound (defined as emergence of new mutations or 2-fold change in phenotypic susceptibility to lopinavir). Incremental resistance was most common in subjects whose baseline isolates had several protease inhibitor-associated mutations, but < 40-fold reduced susceptibility to lopinavir at baseline. Mutations V82A, I54V and M46I emerged most frequently. Mutations L33F, I50V and V32I combined with I47V/A were also observed. The 19 isolates demonstrated a 4.3-fold increase in IC50 compared to baseline isolates (from 6.2- to 43-fold, compared to wild-type virus).

Genotypic correlates of reduced phenotypic susceptibility to lopinavir in viruses selected by other protease inhibitors. The in vitro antiviral activity of lopinavir against 112 clinical isolates taken from patients failing therapy with one or more protease inhibitors was assessed. Within this panel, the following mutations in HIV protease were associated with reduced in vitro susceptibility to lopinavir: L10F/I/R/V, K20M/R, L24I, M46I/L, F53L, I54L/T/V, L63P, A71I/L/T/V, V82A/F/T, I84V and L90M. The median EC50 of lopinavir against isolates with 0 − 3, 4 − 5, 6 − 7 and 8 − 10 mutations at the above amino acid positions was 0.8, 2.7 13.5 and 44.0-fold higher than the EC50 against wild type HIV, respectively. The 16 viruses that displayed > 20-fold change in susceptibility all contained mutations at positions 10, 54, 63 plus 82 and/or 84. In addition, they contained a median of 3 mutations at amino acid positions 20, 24, 46, 53, 71 and 90. In addition to the mutations described above, mutations V32I and I47A have been observed in rebound isolates with reduced lopinavir susceptibility from protease inhibitor experienced patients receiving Lopinavir and Ritonavir Tablets therapy, and mutations I47A and L76V have been observed in rebound isolates with reduced lopinavir susceptibility from patients receiving Lopinavir and Ritonavir Tablets therapy.

Conclusions regarding the relevance of particular mutations or mutational patterns are subject to change with additional data, and it is recommended to always consult current interpretation systems for analysing resistance test results.

Antiviral activity of Lopinavir and Ritonavir Tablets in patients failing protease inhibitor therapy 

The clinical relevance of reduced in vitro susceptibility to lopinavir has been examined by assessing the virologic response to Lopinavir and Ritonavir Tablets therapy, with respect to baseline viral genotype and phenotype, in 56 patients previous failing therapy with multiple protease inhibitors. The EC50 of lopinavir against the 56 baseline viral isolates ranged from 0.6 to 96-fold higher than the EC50 against wild type HIV. After 48 weeks of treatment with Lopinavir and Ritonavir Tablets, Efavirenz and nucleoside reverse transcriptase inhibitors, plasma HIV RNA ≤ 400 copies/ml was observed in 93% (25/27), 73% (11/15), and 25% (2/8) of patients with < 10-fold, 10 to 40-fold, and > 40-fold reduced susceptibility to lopinavir at baseline, respectively. In addition, virologic response was observed in 91% (21/23), 71% (15/21) and 33% (2/6) patients with 0 − 5, 6 − 7, and 8 − 10 mutations of the above mutations in HIV protease associated with reduced in vitro susceptibility to lopinavir. Since these patients had not previously been exposed to either Lopinavir and Ritonavir Tablets or Efavirenz, part of the response may be attributed to the antiviral activity of efavirenz, particularly in patients harbouring highly lopinavir resistant virus. The study did not contain a control arm of patients not receiving Lopinavir and Ritonavir Tablets.

Cross-resistance 

Activity of other protease inhibitors against isolates that developed incremental resistance to lopinavir after Lopinavir and Ritonavir Tablets therapy in protease inhibitor experienced patients: The presence of cross resistance to other protease inhibitors was analysed in 18 rebound isolates that had demonstrated evolution of resistance to lopinavir during 3 Phase II and one Phase III studies of Lopinavir and Ritonavir Tablets in protease inhibitor-experienced patients. The median fold IC50 of lopinavir for these 18 isolates at baseline and rebound was 6.9- and 63fold, respectively, compared to wild type virus. In general, rebound isolates either retained (if cross-resistant at baseline) or developed significant cross-resistance to indinavir, saquinavir and atazanavir. Modest decreases in amprenavir activity were noted with a median increase of IC50 from 3.7- to 8-fold in the baseline and rebound isolates, respectively. Isolates retained susceptibility to tipranavir with a median increase of IC50 in baseline and rebound isolates of 1.9- and 1.8–fold, respectively, compared to wild type virus. Please refer to the Aptivus Summary of Product Characteristics for additional information on the use of tipranavir, including genotypic predictors of response, in treatment of lopinavir-resistant HIV-1 infection.

Clinical results 

The effects of Lopinavir and Ritonavir Tablets (in combination with other antiretroviral agents) on biological markers (plasma HIV RNA levels and CD4+ T-cell counts) have been investigated in controlled studies of Lopinavir and Ritonavir Tablets of 48 to 360 weeks duration. 

Adult Use 

Patients without prior antiretroviral therapy

Study M98-863 was a randomised, double-blind trial of 653 antiretroviral treatment naïve patients investigating Lopinavir and Ritonavir Tablets (400/100 mg twice daily) compared to nelfinavir (750 mg three times daily) plus stavudine and lamivudine. Mean baseline CD4+ T-cell count was 259 cells/mm3 (range: 2 to 949 cells/ mm3) and mean baseline plasma HIV-1 RNA was 4.9 log10 copies/ml (range: 2.6 to 6.8 log10 copies/ml).

One-hundred thirteen nelfinavir-treated patients and 74 lopinavir/ritonavir-treated patients had an HIV RNA above 400 copies/ml while on treatment from Week 24 through Week 96. Of these, isolates from 96 nelfinavir-treated patients and 51 lopinavir/ritonavir-treated patients could be amplified for resistance testing. Resistance to nelfinavir, defined as the presence of the D30N or L90M mutation in protease, was observed in 41/96 (43%) patients. Resistance to lopinavir, defined as the presence of any primary or active site mutations in protease (see above), was observed in 0/51 (0%) patients. Lack of resistance to lopinavir was confirmed by phenotypic analysis.

Study M05-730 was a randomised, open-label, multicenter trial comparing treatment with Lopinavir and Ritonavir Tablets 800/200 mg once daily plus tenofovir DF and Emtricitabine versus Lopinavir and Ritonavir Tablets 400/100 mg twice daily plus tenofovir DF and Emtricitabine in 664 antiretroviral treatment-naïve patients. Given the pharmacokinetic interaction between Lopinavir and Ritonavir Tablets and tenofovir (see section 4.5), the results of this study might not be strictly extrapolable when other backbone regimens are used with Lopinavir and Ritonavir Tablets. Patients were randomised in a 1:1 ratio to receive either Lopinavir and Ritonavir Tablets 800/200 mg once daily (n = 333) or Lopinavir and Ritonavir Tablets 400/100 mg twice daily (n = 331). Further stratification within each group was 1:1 (tablet versus soft capsule). Patients were administered either the tablet or the soft capsule formulation for 8 weeks, after which all patients were administered the tablet formulation once daily or twice daily for the remainder of the study. Patients were administered Emtricitabine 200 mg once daily and tenofovir DF 300 mg once daily. Protocol defined non-inferiority of once-daily dosing compared with twice-daily dosing was demonstrated if the lower bound of the 95% confidence interval for the difference in proportion of subjects responding (once daily minus twice daily) excluded -12% at Week 48. Mean age of patients enrolled was 39 years (range: 19 to 71); 75% were Caucasian, and 78% were male. Mean baseline CD4+ T-cell count was 216 cells/mm3 (range: 20 to 775 cells/mm3) and mean baseline plasma HIV-1 RNA was 5.0 log10 copies/ml (range: 1.7 to 7.0 log10 copies/ml).

Through Week 96, genotypic resistance testing results were available from 25 patients in the QD group and 26 patients in the BID group who had incomplete virologic response. In the QD group, no patient demonstrated lopinavir resistance, and in the BID group, 1 patient who had significant protease inhibitor resistance at baseline demonstrated additional lopinavir resistance on study.

Sustained virological response to Lopinavir and Ritonavir Tablets (in combination with nucleoside/nucleotide reverse transcriptase inhibitors) has been also observed in a small Phase II study (M97-720) through 360 weeks of treatment. One hundred patients were originally treated with Lopinavir and Ritonavir Tablets in the study (including 51 patients receiving 400/100 mg twice daily and 49 patients at either 200/100 mg twice daily or 400/200 mg twice daily). All patients converted to open-label Lopinavir and Ritonavir Tablets at the 400/100 mg twice-daily dose between week 48 and week 72. Thirty-nine patients (39%) discontinued the study, including 16 (16%) discontinuations due to adverse events, one of which was associated with a death. Sixty-one patients completed the study (35 patients received the recommended 400/100 mg twice-daily dose throughout the study).

Through 360 weeks of treatment, genotypic analysis of viral isolates was successfully conducted in 19 of 28 patients with confirmed HIV RNA above 400 copies/ml revealed no primary or active site mutations in protease (amino acids at positions 8, 30, 32, 46, 47, 48, 50, 82, 84 and 90) or protease inhibitor phenotypic resistance.

Patients with prior antiretroviral therapy

M06-802 was a randomised open-label study comparing the safety, tolerability and antiviral activity of once-daily and twice-daily dosing of lopinavir/ritonavir tablets in 599 subjects with detectable viral loads while receiving their current antiviral therapy. Patients had not been on prior lopinavir/ritonavir therapy. They were randomised in a 1:1 ratio to receive either lopinavir/ritonavir 800/200 mg once daily (n = 300) or lopinavir/ritonavir 400/100 mg twice daily (n = 299). Patients were administered at least two nucleoside/nucleotide reverse transcriptase inhibitors selected by the investigator. The enrolled population was moderately PIexperienced with more than half of patients having never received prior PI and around 80% of patients presenting a viral strain with less than 3 PI mutations. Mean age of patients enrolled was 41 years (range: 21 to 73); 51% were Caucasian and 66% were male. Mean baseline CD4+ Tcell count was 254 cells/mm3 (range: 4 to 952 cells/mm3) and mean baseline plasma HIV-1 RNA was 4.3 log10 copies/ml (range: 1.7 to 6.6 log10 copies/ml). Around 85% of patients had a viral load of < 100,000 copies/ml.

Through Week 48, genotypic resistance testing results were available from 75 patients in the QD group and 75 patients in the BID group who had incomplete virologic response. In the QD group, 6/75 (8%) patients demonstrated new primary protease inhibitor mutations (codons 30, 32, 48, 50, 82, 84, 90), as did 12/77 (16%) patients in the BID group.

Paediatric Use 

M98-940 was an open-label study of a liquid formulation of Lopinavir and Ritonavir Tablets in 100 antiretroviral naïve (44%) and experienced (56%) paediatric patients. All patients were nonnucleoside reverse transcriptase inhibitor naïve. Patients were randomised to either 230 mg lopinavir/57.5 mg ritonavir per m2 or 300 mg lopinavir/75 mg ritonavir per m2. Naïve patients also received nucleoside reverse transcriptase inhibitors. Experienced patients received nevirapine plus up to two nucleoside reverse transcriptase inhibitors. Safety, efficacy and pharmacokinetic profiles of the two dose regimens were assessed after 3 weeks of therapy in each patient. Subsequently, all patients were continued on the 300/75 mg per m2 dose. Patients had a mean age of 5 years (range 6 months to 12 years) with 14 patients less than 2 years old and 6 patients one year or less. Mean baseline CD4+ T-cell count was 838 cells/mm3 and mean baseline plasma HIV-1 RNA was 4.7 log10 copies/ml.

KONCERT/PENTA 18 is a prospective multicentre, randomised, open-label study that evaluated the pharmacokinetic profile, efficacy and safety of twice-daily versus once-daily dosing of lopinavir/ritonavir 100 mg/25 mg tablets dosed by weight as part of combination antiretroviral therapy (cART) in virologically suppressed HIV-1 infected children (n=173). Children were eligible when they were aged <18 years, ≥15 kg in weight, receiving cART that included lopinavir/ritonavir, HIV-1 ribonucleic acid (RNA) <50 copies/ml for at least 24 weeks and able to swallow tablets. At week 48, the efficacy and safety with twice-daily dosing (n=87) in the paediatric population given lopinavir/ritonavir 100 mg/25 mg tablets was consistent with the efficacy and safety findings in previous adult and paediatric studies using lopinavir/ritonavir twice daily. The percentage of patients with confirmed viral rebound >50 copies/ml during 48 weeks of follow-up was higher in the paediatric patients receiving lopinavir/ritonavir tablets once daily (12%) than in patients receiving the twice-daily dosing (8%, p = 0.19), mainly due to lower adherence in the once-daily group. The efficacy data favouring the twice-daily regimen are reinforced by a differential in pharmacokinetic parameters significantly favouring the twice-daily regimen (see section 5.2).


The pharmacokinetic properties of lopinavir co-administered with ritonavir have been evaluated in healthy adult volunteers and in HIV-infected patients; no substantial differences were observed between the two groups. Lopinavir is essentially completely metabolised by CYP3A. Ritonavir inhibits the metabolism of lopinavir, thereby increasing the plasma levels of lopinavir. Across studies, administration of Lopinavir and Ritonavir Tablets 400/100 mg twice daily yields mean steady-state lopinavir plasma concentrations 15 to 20-fold higher than those of ritonavir in HIV-infected patients. The plasma levels of ritonavir are less than 7% of those obtained after the ritonavir dose of 600 mg twice daily. The in vitro antiviral EC50 of lopinavir is approximately 10-fold lower than that of ritonavir. Therefore, the antiviral activity of Lopinavir and Ritonavir Tablets is due to lopinavir.

Absorption 

Multiple dosing with 400/100 mg Lopinavir and Ritonavir Tablets twice daily for 2 weeks and without meal restriction produced a mean ± SD lopinavir peak plasma concentration (Cmax) of 12.3 ± 5.4 μg/ml, occurring approximately 4 hours after administration. The mean steady-state trough concentration prior to the morning dose was 8.1 ± 5.7 μg/ml. Lopinavir AUC over a 12 hour dosing interval averaged 113.2 ± 60.5 μg•h/ml. The absolute bioavailability of lopinavir coformulated with ritonavir in humans has not been established.

Effects of food on oral absorption 

Administration of a single 400/100 mg dose of Lopinavir and Ritonavir Tablets under fed conditions (high fat, 872 kcal, 56% from fat) compared to fasted state was associated with no significant changes in Cmax and AUCinf. Therefore, Lopinavir and Ritonavir Tablets may be taken with or without food. Lopinavir and Ritonavir Tablets have also shown less pharmacokinetic variability under all meal conditions compared to Lopinavir and Ritonavir Tablets soft capsules.

Distribution 

At steady state, lopinavir is approximately 98 − 99% bound to serum proteins. Lopinavir binds to both alpha-1-acid glycoprotein (AAG) and albumin however; it has a higher affinity for AAG. At steady state, lopinavir protein binding remains constant over the range of observed concentrations after 400/100 mg Lopinavir and Ritonavir Tablets twice daily, and is similar between healthy volunteers and HIV-positive patients.

Biotransformation 

In vitro experiments with human hepatic microsomes indicate that lopinavir primarily undergoes oxidative metabolism. Lopinavir is extensively metabolised by the hepatic cytochrome P450 system, almost exclusively by isozyme CYP3A. Ritonavir is a potent CYP3A inhibitor which inhibits the metabolism of lopinavir and therefore, increases plasma levels of lopinavir. A 14Clopinavir study in humans showed that 89% of the plasma radioactivity after a single 400/100 mg Lopinavir and Ritonavir Tablets dose was due to parent active substance. At least 13 lopinavir oxidative metabolites have been identified in man. The 4-oxo and 4-hydroxymetabolite epimeric pair are the major metabolites with antiviral activity, but comprise only minute amounts of total plasma radioactivity. Ritonavir has been shown to induce metabolic enzymes, resulting in the induction of its own metabolism, and likely the induction of lopinavir metabolism. Pre-dose lopinavir concentrations decline with time during multiple dosing, stabilising after approximately 10 days to 2 weeks.

Elimination 

After a 400/100 mg 14C-lopinavir/ritonavir dose, approximately 10.4 ± 2.3% and 82.6 ± 2.5% of an administered dose of 14C-lopinavir can be accounted for in urine and faeces, respectively. Unchanged lopinavir accounted for approximately 2.2% and 19.8% of the administered dose in urine and faeces, respectively. After multiple dosing, less than 3% of the lopinavir dose is excreted unchanged in the urine. The effective (peak to trough) half-life of lopinavir over a 12 hour dosing interval averaged 5 − 6 hours, and the apparent oral clearance (CL/F) of lopinavir is 6 to 7 l/h.

Once-daily dosing: the pharmacokinetics of once daily Lopinavir and Ritonavir Tablets have been evaluated in HIV-infected subjects naïve to antiretroviral treatment. Lopinavir and Ritonavir Tablets 800/200 mg was administered in combination with Emtricitabine 200 mg and tenofovir DF 300 mg as part of a once-daily regimen. Multiple dosing of 800/200 mg Lopinavir and Ritonavir Tablets once daily for 2 weeks without meal restriction (n=16) produced a mean ± SD lopinavir peak plasma concentration (Cmax) of 14.8 ± 3.5 μg/ml, occurring approximately 6 hours after administration. The mean steady-state trough concentration prior to the morning dose was 5.5 ± 5.4 μg/ml. Lopinavir AUC over a 24 hour dosing interval averaged 206.5 ± 89.7 μg•h/ml.

As compared to the BID regimen, the once-daily dosing is associated with a reduction in the

Cmin/Ctrough values of approximately 50%. 

Special Populations 

Paediatrics 

There are limited pharmacokinetic data in children below 2 years of age. The pharmacokinetics of Lopinavir and Ritonavir Tablets oral solution 300/75 mg/m2 twice daily and 230/57.5 mg/m2 twice daily have been studied in a total of 53 paediatric patients, ranging in age from 6 months to 12 years. The lopinavir mean steady-state AUC, Cmax, and Cmin were 72.6 ± 31.1 μg•h/ml, 8.2 ± 2.9 μg/ml and 3.4 ± 2.1 μg/ml, respectively after Lopinavir and Ritonavir Tablets oral solution 230/57.5 mg/m2 twice daily without nevirapine (n=12), and were 85.8 ± 36.9 μg•h/ml, 10.0 ± 3.3 μg/ml and 3.6 ± 3.5 μg/ml, respectively after 300/75 mg/m2 twice daily with nevirapine (n=12). The 230/57.5 mg/m2 twice-daily regimen without nevirapine and the 300/75 mg/m2 twice-daily regimen with nevirapine provided lopinavir plasma concentrations similar to those obtained in adult patients receiving the 400/100 mg twice-daily regimen without nevirapine. 

Gender, Race and Age  

Lopinavir and Ritonavir Tablets pharmacokinetics have not been studied in older people. No age or gender related pharmacokinetic differences have been observed in adult patients.

Pharmacokinetic differences due to race have not been identified.

Pregnancy and postpartum 

In an open-label pharmacokinetic study, 12 HIV-infected pregnant women who were less than 20 weeks of gestation and on combination antiretroviral therapy initially received lopinavir/ritonavir 400 mg/100 mg (two 200/50 mg tablets) twice daily up to a gestational age of 30 weeks. At 30 weeks age of gestation, the dose was increased to 500/125 mg (two 200/50 mg tablets plus one 100/25 mg tablet) twice daily until subjects were 2 weeks postpartum. Plasma concentrations of lopinavir were measured over four 12-hour periods during second trimester (20-24 weeks gestation), third trimester before dose increase (30 weeks gestation), third trimester after dose increase (32 weeks gestation), and at 8 weeks post-partum. The dose increase did not result in a significant increase in the plasma lopinavir concentration. 

In another open-label pharmacokinetic study, 19 HIV-infected pregnant women received lopinavir/ritonavir 400/100 mg twice daily as part of combination antiretroviral therapy during pregnancy from before conception. A series of blood samples were collected pre-dose and at intervals over the course of 12 hours in trimester 2 and trimester 3, at birth, and 4–6 weeks postpartum (in women who continued treatment post-delivery) for pharmacokinetic analysis of total and unbound levels of plasma lopinavir concentrations.

The pharmacokinetic data from HIV-1 infected pregnant women receiving lopinavir/ritonavir tablets 400/100 mg twice daily are presented in Table 6 (see section 4.2).

Renal Insufficiency  

Lopinavir and Ritonavir Tablets pharmacokinetics have not been studied in patients with renal insufficiency; however, since the renal clearance of lopinavir is negligible, a decrease in total body clearance is not expected in patients with renal insufficiency.

Hepatic Insufficiency 

The steady state pharmacokinetic parameters of lopinavir in HIV-infected patients with mild to moderate hepatic impairment were compared with those of HIV-infected patients with normal hepatic function in a multiple dose study with lopinavir/ritonavir 400/100 mg twice daily. A limited increase in total lopinavir concentrations of approximately 30% has been observed which is not expected to be of clinical relevance (see section 4.2).


Repeat-dose toxicity studies in rodents and dogs identified major target organs as the liver, kidney, thyroid, spleen and circulating red blood cells. Hepatic changes indicated cellular swelling with focal degeneration. While exposure eliciting these changes were comparable to or below human clinical exposure, dosages in animals were over 6-fold the recommended clinical dose. Mild renal tubular degeneration was confined to mice exposed with at least twice the recommended human exposure; the kidney was unaffected in rats and dogs. Reduced serum thyroxin led to an increased release of TSH with resultant follicular cell hypertrophy in the thyroid glands of rats. These changes were reversible with withdrawal of the active substance and were absent in mice and dogs. Coombs-negative anisocytosis and poikilocytosis were observed in rats, but not in mice or dogs. Enlarged spleens with histiocytosis were seen in rats but not other species. Serum cholesterol was elevated in rodents but not dogs, while triglycerides were elevated only in mice. 

During in vitro studies, cloned human cardiac potassium channels (HERG) were inhibited by 30% at the highest concentrations of lopinavir/ritonavir tested, corresponding to a lopinavir exposure 7-fold total and 15-fold free peak plasma levels achieved in humans at the maximum recommended therapeutic dose. In contrast, similar concentrations of lopinavir/ritonavir demonstrated no repolarisation delay in the canine cardiac Purkinje fibres. Lower concentrations of lopinavir/ritonavir did not produce significant potassium (HERG) current blockade. Tissue distribution studies conducted in the rat did not suggest significant cardiac retention of the active substance; 72-hour AUC in heart was approximately 50% of measured plasma AUC. Therefore, it is reasonable to expect that cardiac lopinavir levels would not be significantly higher than plasma levels.

In dogs, prominent U waves on the electrocardiogram have been observed associated with prolonged PR interval and bradycardia. These effects have been assumed to be caused by electrolyte disturbance. 

The clinical relevance of these preclinical data is unknown, however, the potential cardiac effects of this product in humans cannot be ruled out (see also sections 4.4 and 4.8). 

In rats, embryofoetotoxicity (pregnancy loss, decreased foetal viability, decreased foetal body weights, increased frequency of skeletal variations) and postnatal developmental toxicity (decreased survival of pups) was observed at maternally toxic dosages. The systemic exposure to lopinavir/ritonavir at the maternal and developmental toxic dosages was lower than the intended therapeutic exposure in humans. 

Long-term carcinogenicity studies of lopinavir/ritonavir in mice revealed a nongenotoxic, mitogenic induction of liver tumours, generally considered to have little relevance to human risk. 

Carcinogenicity studies in rats revealed no tumourigenic findings. Lopinavir/ritonavir was not found to be mutagenic or clastogenic in a battery of in vitro and in vivo assays including the Ames bacterial reverse mutation assay, the mouse lymphoma assay, the mouse micronucleus test and chromosomal aberration assays in human lymphocytes.
