Posology
5-Fluorouracil should be administered only under the supervision of a qualified physician with extensive experience in cytotoxic treatment.

Patients must be carefully and frequently monitored during the treatment. The risks and benefits to individual patients should be carefully considered before each treatment.
Method of administration
5-Fluorouracil can be administered by intravenous injection as bolus, infusion or continuous infusion for upto several days.
Intravenous administration:
The dose of 5-Fluorouracil and the treatment schedule depends on the chosen treatment regimen, the indication, the general status and previous treatment of the patient. Treatment regimens vary in the combination of 5-Fluorouracil with other cytotoxic agents or dose of concomitantly used Folinic Acid.
The number of cycles used should be decided by the treating clinician depending on local treatment protocols and guidelines; taking into consideration treatment success and tolerability in individual patients.
Initial treatment should be given in hospital.
Reduction of the dose is advisable in patients with any of the following:
1. Cachexia
2. Major surgery within preceding 30 days
3. Reduced bone marrow function
4. Impaired hepatic or renal function

Adults and elderly patients receiving 5-Fluorouracil should be monitored prior to each dose for haematological (platelet, leucocyte, and granulocyte counts), gastrointestinal (stomatitis, diarrhoea, bleeding from the gastrointestinal tract), and neurological toxicity, and, if necessary, the dose of
5-Fluorouracil may be either reduced or withheld.
Necessity of dosage adjustment or discontinuation of the medicinal product depends on the occurrence of undesirable effects. Haematological toxicities such as reduced leukocytes (≤ 3500/mm3) and/or platelet counts (≤ 100000/mm3) can require treatment interruption. Resumption of treatment must be decided by the treating clinician depending upon the clinical scenario.
Colorectal cancer:
5-Fluorouracil is used in the treatment of colon and rectal cancers in a number of treatment regimens. 5-Fluorouracil is preferably used along with Folinic Acid. Commonly used treatment regimens also combine 5-Fluorouracil and Folinic Acid with other chemotherapeutic agents such as Irinotecan (FOLFIRI and FLIRI), Oxaliplatin (FOLFOX) or both Irinotecan and Oxaliplatin (FOLFIRINOX).
The commonly used dose range of 5-Fluorouracil varies from 200-600mg/m2 of body surface. The dose also varies depending on administration as intravenous bolus or as continuous intravenous infusion.
The dose schedules also vary depending on the chemotherapy regimen, and 5-Fluorouracil dose could be repeated weekly, bimonthly or monthly.
The number of cycles varies with the treatment regimens used and also depends on the clinical decision based on treatment success and tolerability.

Breast cancer:
5-Fluorouracil is commonly used in chemotherapy regimens in combination with Cyclophosphamide and Methotrexate (CMF), or Epirubicin, Cyclophosphamide (FEC) or Methotrexate and Leucovorin (MFL). The usual dose range is 500- 600mg/m2 body surface as an intravenous bolus and repeated every 3–4 weeks as necessary. In adjuvant treatment of primary invasive breast cancer, duration of treatment will usually continue for 6 cycles.
Gastric cancer and cancer of gastroesophageal junction:
Perioperative chemotherapy with ECF regimen (Epirubicin, Cisplatin, 5-Fluorouracil) is currently recommended. The recommended dose of 5-Fluorouracil is 200mg/m2 body surface per day given as continuous intravenous infusion for 3 weeks. Six cycles are recommended but this depends on treatment success and tolerability of medicinal product by the patient.
Oesophageal cancer:
5-Fluorouracil is commonly used in combination with Cisplatin; or Cisplatin and Epirubicin; or Epirubicin and Oxaliplatin. Dose varies between 200- 1000mg/m2 body surface per day as continuous intravenous infusion over several days and repeated cyclically depending upon regimen.
For cancers involving lower part of oesophagus, perioperative chemotherapy with ECF regimen (Epirubicin, Cisplatin, 5-Fluorouracil) is commonly recommended. The recommended dose of 5-Fluorouracil is 200mg/m2 body surface per day given as continuous intravenous infusion for 3 weeks and repeated cyclically.
Concerning administration of 5-Fluorouracil/Cisplatin in combination with radiotherapy, please refer to the literature.

Pancreatic cancer:
5-Fluorouracil is preferably used in combination with Folinic Acid or Gemcitabine. Dose varies between 200 – 500mg/m2 body surface per day as intravenous bolus injection or intravenous infusion, depending on the regimen and repeated cyclically.
Head and neck cancer:
5-Fluorouracil is preferably used in combination with Cisplatin or Carboplatin. Dose varies between 600 – 1200mg/m2 body surface per day as continuous intravenous infusion over several days and repeated cyclically depending upon regimen.
Concerning administration of 5-Fluorouracil/Cisplatin or Carboplatin in combination with radiotherapy, please refer to the literature.
Special populations
Renal or hepatic impairment
Caution is advised and the dose might need to be reduced in patients with renal or hepatic impairment.
Paediatric population
Fluorouracil is not recommended for use in children due to insufficient data on safety and efficacy.
Elderly
No dosage adjustment is necessary.

Hypersensitivity to Fluorouracil or to any of the excipients listed in section 6.1. Fluorouracil is contraindicated in the following: • Serious infections (e.g. Herpes zoster, chickenpox). • Seriously debilitated patients. • Bone marrow depression after radiotherapy or treatment with other antineoplastic agents. • Management of non-malignant disease • Serious liver impairment • Fluorouracil must not be given in combination with Brivudine, Sorivudine and analogues. Brivudine, Sorivudine and analogues are potent inhibitors of the Fluorouracil-metabolising enzyme Dihydropyrimidine dehydrogenase (DPD) (see section 4.4 and 4.5). • Fluorouracil must not be given to patients homozygotic for Dihydropyrimidine dehydrogenase (DPD). • Fluorouracil is strictly contraindicated in pregnant or breastfeeding women.

It is recommended that Fluorouracil should only be given by, or under the strict supervision of a qualified physician who is conversant with the use of potent antimetabolites and has the facilities for regular monitoring of clinical, biochemical and haematological effects during and after administration.
All patients should be admitted to hospital for initial treatment.
Adequate treatment with Fluorouracil is usually followed by leucopenia, the lowest white blood cell (WBC) count commonly being observed between the 7th and 14th day of the first course, but occasionally being delayed for as long as 20 days. The count usually returns to normal by the 30th day. Daily monitoring of platelet and WBC count is recommended and treatment should be stopped if platelets fall below 100,000 per mm3 or the WBC count falls below 3,500 per mm3. If the total count is less than 2000 per mm3, and especially if there is granulocytopenia, it is recommended that the patient be placed in protective isolation in the hospital and treated with appropriate measures to prevent systemic infection.
Treatment should also be stopped at the first sign of oral ulceration or if there is evidence of gastrointestinal side effects such as stomatitis, diarrhoea, bleeding from the GI tract or haemorrhage at any site, oesophagopharyngitis or intractable vomiting. Fluorouracil should be resumed only when the patient has recovered from the above signs. The ratio between effective and toxic dose is small and therapeutic response is unlikely without some degree of toxicity. Care must be taken therefore, in the selection of patients and adjustment of dosage. Treatment should be stopped in case of severe toxicity.

Fluorouracil should be used with extreme caution in poor risk patients who have recently undergone surgery, have a history of high-dose irradiation of bone marrow-bearing areas (pelvis, spine, ribs, etc.) or prior use of another chemotherapeutic agent causing myelosuppression, have a widespread involvement of bone marrow by metastatic tumours, or those with reduced renal or liver function, jaundice or who have a poor nutritional state.
Isolated cases of angina, ECG abnormalities and rarely, myocardial infarction have been reported following administration of Fluorouracil. Care should be therefore be exercised in treating patients who experience chest pain during courses of treatment, or patients with a history of heart disease. Careful consideration should be given to re-administration of Fluorouracil after a documented cardiovascular reaction (arrhythmia, angina, ST segment changes) as there is a risk of sudden death.

5
Severe toxicity and fatalities are more likely in poor risk patients, but have occasionally occurred in patients who are in relatively good condition. Any form of therapy which adds to the stress of the patient, interferes with nutritional uptake or depresses the bone marrow function, will increase the toxicity of fluorouracil. If therapy is continued careful monitoring of the patient is required.
Dihydropyrimidine dehydrogenase (DPD) plays an important role in the metabolism of Fluorouracil. There have been reports of increased Fluorouracil toxicity in patients who have reduced activity/deficiency of DPD. If applicable, determination of DPD enzyme activity is indicated prior to the treatment with 5-fluoropyrimidines.
The most pronounced and dose-limiting toxic effects of fluorouracil are on the normal, rapidly proliferating cells of the bone marrow and the lining of the gastrointestinal tract. The immunosuppressive effect of fluorouracil may cause a higher incidence of microbial infections, delayed wound healing and bleeding of the gums.
Nucleoside analogues, e.g. Brivudine and Sorivudine, which affect DPD activity may cause increased plasma concentrations and increased toxicity of Fluoropyrimidines (see section 4.5). Therefore, an interval of at least 4 weeks between administration of Fluorouracil and Brivudine, Sorivudine or analogues should be kept. In the case of accidental administration of nucleoside analogues to patients treated with Fluorouracil, effective measures should be taken to reduce Fluorouracil toxicity. Immediate hospitalisation is recommended. Any measure to prevent systemic infections and dehydration should be commenced.
Vaccination with a live vaccine should be avoided in patients receiving Fluorouracil due to the potential for serious or fatal infections. Contact should be avoided with people who have recently been treated with polio virus vaccine.

It is not advisable to prolonged exposure to sunlight because of the risk of photosensitivity.
Use with caution in patients who have had high-dose pelvic radiation.
Combination of 5-Fluorouracil and Folinic Acid
The toxicity profile of 5-Fluorouracil may be enhanced or shifted by Folinic Acid. The most common manifestations are leucopenia, mucositis, stomatitis and/or diarrhoea which may be dose limiting. When 5-Fluorouracil and Folinic Acid are used in combination, the Fluorouracil dosage must be reduced more in cases of toxicity than when Fluorouracil is used alone. Toxicities observed in patients treated with the combination are qualitatively similar to those observed in patients treated with 5-Fluorouracil alone.
Gastrointestinal toxicities are observed more commonly and may be more severe or even life threatening (particularly stomatitis and diarrhoea). In severe cases, 5-Fluorouracil and Folinic Acid must be withdrawn, and supportive intravenous therapy initiated. Patients should be instructed to consult their treating physician immediately if stomatitis (mild to moderate ulcers) and/or diarrhoea (watery stools or bowel movements) two times per day occur.
Particular care should be taken in the treatment of elderly or debilitated patients, as these patients may be at increased risk of severe toxicity.
Women of childbearing potential and men have to use effective contraception during and up to 6 months after treatment.
Patients taking Phenytoin concomitantly with Fluorouracil should undergo regular testing because of the possibility of an elevated plasma level of Phenytoin.

Floryl contains Sodium:
Floryl contains 7.78mmol (178.2mg) of Sodium per maximum daily dose (600mg/m2). This should be taken into consideration by patients on a controlled Sodium diet.

Various agents have been reported to biochemically modulate the anti-tumour efficacy or toxicity of Fluorouracil. Common drugs include Methotrexate, Metronidazole, Leucovorin, Interferon alfa and Allopurinol.
Both the efficacy and toxicity of 5-Fluorouracil may be increased when 5-Fluorouracil is used in combination with Folinic Acid. Side effects may be more pronounced and severe diarrhoea may occur. Life-threatening diarrhoeas have been observed if 600mg/m² of Fluorouracil (i.v. bolus once weekly) is given together with Folinic Acid.
In combination with other myelosuppressive substances, dosage adjustment is necessary. Concomitant or previous radiation therapy may require dosage reduction. The cardiotoxicity of Anthracyclines may be increased.
Fluorouracil should be avoided in combination with Clozapine due to increased risk of agranulocytosis.
Increased incidence of cerebral infarction has been reported in oropharyngeal cancer patients treated with Fluorouracil and Cisplatin.
Marked elevations of prothrombin time and INR have been reported in a few patients stabilised on Warfarin therapy following initiation of Fluorouracil regimes.
The enzyme Dihydropyrimidine dehydrogenase (DPD) plays an important role in the metabolism of Fluorouracil. Nucleoside analogues, e.g. Brivudine and Sorivudine, may induce an increase in plasma concentrations of Fluorouracil or other Fluoropyrimidines accompanied by toxicological reactions. Therefore, a time interval of minimum 4 weeks between administration of Fluorouracil and Brivudine, Sorivudine and analogues should be kept.
If applicable, determination of DPD enzyme activity is indicated prior to treatment with 5- Fluoropyrimidines.

Cimetidine, Metronidazole and Interferon may increase the plasma level of 5-Fluorouracil, thereby increasing the toxicity of 5-Fluorouracil.
In patients receiving Phenytoin and Fluorouracil concomitantly, an increase of Phenytoin plasma concentration has been reported resulting in symptoms of Phenytoin toxicity.
Fluorouracil enhances the action of other cytostatic drugs and irradiation therapy (see section 4.2).
In patients receiving Cyclophosphamide, Methotrexate and 5-Fluorouracil, addition of Thiazide diuretics resulted in a more pronounced decrease in the number of granulocytes when compared to patients not receiving Thiazides.
Hepatotoxicity (increase in Alkaline phosphatases, Transaminases or Bilirubin) has been observed commonly in patients receiving 5-Fluorouracil in combination with Levamisole.
In patients with breast cancer, combination therapy with Cyclophosphamide, Methotrexate, 5-Fluorouracil and Tamoxifen has been reported to increase the risk of thromboembolic events.

Serious, potentially life-threatening mucositis may occur following co-administration of Vinorelbine and 5-Fluorouracil/Folinic Acid.
Vaccination with live vaccines should be avoided in immunocompromised patients.

Pregnancy:
Fluorouracil is strictly contraindicated in pregnant and breastfeeding women.
There are no adequate and well-controlled studies in pregnant women, however, foetal defects and miscarriages have been reported.
Women of childbearing potential should be advised to avoid becoming pregnant and use an effective method of contraception during treatment with Fluorouracil and up to 6 months afterwards (see section 4.4). If the drug is used during pregnancy, or if the patient becomes pregnant while taking the drug, the patient should be fully informed of the potential hazard to the foetus and genetic counselling is recommended. Fluorouracil should be used during pregnancy only if potential benefit justifies the potential risk for foetus.
Fertility:
Men treated with Fluorouracil are advised not to father a child during and for up to 6 months following cessation of treatment (see section 4.4). Advice on conservation of sperm should be sought prior to treatment because of the possibility of irreversible infertility due to therapy with Fluorouracil.
Breastfeeding:
Since it is not known whether Fluorouracil passes into breast milk, breastfeeding must be discontinued if the mother is treated with Fluorouracil.

No studies on the effects on the ability to drive and use machinery have been performed.
Fluorouracil may induce side effects such as nausea and vomiting. It can also produce adverse event on nervous system and visual changes which could interfere with driving or the usage of heavy machinery.

Patients who have been exposed to an overdose of Fluorouracil should be monitored haematologically for at least four weeks. Should abnormalities appear, appropriate therapy should be utilized.

Pharmacotherapeutic group: Pyrimidine analogues.
ATC code: L01BC02
Fluorouracil is an analogue of Uracil, a component of Ribonucleic Acid. The drug is believed to function as an antimetabolite. After intracellular conversion to the active deoxynucleotide, it interferes with the synthesis of DNA by blocking the conversion of Deoxyuridylic Acid to Thymidylic Acid by the cellular enzyme Thymidylate Synthetase. Fluorouracil may also interfere with RNA synthesis.

After intravenous administration, Fluorouracil is distributed through the body water and disappears from the blood within 3 hours. It is preferentially taken up by actively dividing tissues and tumours after conversion to its nucleotide. Fluorouracil readily enters the cerebrospinal fluid and brain tissue.
Following IV administration, the plasma elimination half-life averages about 16 minutes and is dose dependant. Following a single IV dose of Fluorouracil approximately 15% of the dose is excreted unchanged in the urine within 6 hours; over 90% of this is excreted in the first hour. The remainder is mostly metabolised in the liver to inactive metabolites by the usual body mechanisms for Uracil. Hepatic impairment may result in slower metabolism of Fluorouracil and may require dose adjustment.

Preclinical information has not been included, as the clinical toxicity profile of Fluorouracil has been established after many years of clinical use.
