· Primary Hypercholesterolemia or Mixed Dyslipidemia
Fenofibrate Tablets is indicated as adjunctive therapy to diet to reduce elevated low-density lipoprotein cholesterol (LDL-C), total cholesterol (Total-C), Triglycerides and apolipoprotein B (Apo B), and to increase high-density lipoprotein cholesterol (HDL-C) in adult patients with primary hypercholesterolemia or mixed dyslipidemia.
· Severe Hypertriglyceridemia
Fenofibrate Tablets is also indicated as adjunctive therapy to diet for treatment of adult patients with severe hypertriglyceridemia. Improving glycemic control in diabetic patients showing fasting chylomicronemia will usually obviate the need for pharmacologic intervention. Markedly elevated levels of serum triglycerides (e.g. > 2,000 mg/dL) may increase the risk of developing pancreatitis. The effect of fenofibrate therapy on reducing this risk has not been
adequately studied.
· Important Limitations of Use Fenofibrate at a dose equivalent to 145 mg of Fenofibrate Tablets was not shown to reduce coronary heart disease morbidity and mortality in a large, randomized controlled trial of patients with type 2 diabetes mellitus.
Patients should be placed on an appropriate lipid-lowering diet before receiving Fenofibrate Tablets, and should continue this diet during treatment with Fenofibrate Tablets. Fenofibrate Tablets can be given without regard to meals.
The initial treatment for dyslipidemia is dietary therapy specific for the type of lipoprotein abnormality. Excess body weight and excess alcoholic intake may be important factors in hypertriglyceridemia and should be addressed prior to any drug therapy. Physical exercise can be an important ancillary measure. Diseases contributory to hyperlipidemia, such as hypothyroidism or diabetes mellitus should be looked for and adequately treated. Estrogen therapy, thiazide diuretics and beta-blockers, are sometimes associated with massive rises in plasma triglycerides, especially in subjects with familial hypertriglyceridemia. In such cases, discontinuation of the specific etiologic agent may obviate the need for specific drug therapy of hypertriglyceridemia.
Lipid levels should be monitored periodically and consideration should be given to reducing the dosage of Fenofibrate Tablets if lipid levels fall significantly below the targeted range.
Therapy should be withdrawn in patients who do not have an adequate response after two months of treatment with the maximum recommended dose of 145 mg once daily
Warnings and Precautions
· Mortality and Coronary Heart Disease Morbidity
The effect of Fenofibrate Tablets on coronary heart disease morbidity and mortality and non- cardiovascular mortality has not been established.
The Action to Control Cardiovascular Risk in Diabetes Lipid (ACCORD Lipid) trial was a randomized placebo-controlled study of 5518 patients with type 2 diabetes mellitus on background statin therapy treated with fenofibrate. The mean duration of follow-up was 4.7 years. Fenofibrate plus statin combination therapy showed a non-significant 8% relative risk reduction in the primary outcome of major adverse cardiovascular events (MACE), a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular disease death (hazard ratio [HR] 0.92, 95% CI 0.79- 1.08) (p=0.32) as compared to statin monotherapy. In a gender subgroup analysis, the hazard ratio
for MACE in men receiving combination therapy versus statin monotherapy was 0.82 (95% CI 0.69-0.99), and the hazard ratio for MACE in women receiving combination therapy versus statin monotherapy was 1.38 (95% CI 0.98-1.94)
(interaction p=0.01). The clinical significance of this subgroup finding is unclear. The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study was a 5-year randomized, placebo- controlled study of 9795 patients with type 2 diabetes mellitus treated with fenofibrate. Fenofibrate demonstrated a non-significant 11% relative reduction in the primary outcome of coronary heart disease events (hazard ratio [HR] 0.89, 95% CI 0.75-1.05, p=0.16) and a significant 11% reduction in the secondary outcome of total cardiovascular disease events (HR 0.89 [0.80-0.99], p=0.04). There was a non-significant 11% (HR 1.11 [0.95, 1.29], p=0.18) and 19% (HR 1.19 [0.90, 1.57], p=0.22) increase in total and coronary heart disease mortality, respectively, with fenofibrate as compared to placebo.
Because of chemical, pharmacological, and clinical similarities between Fenofibrate Tablets (fenofibrate tablets), clofibrate, and gemfibrozil, the adverse findings in 4 large randomized, placebo controlled clinical studies with these other fibrate drugs may also apply to Fenofibrate Tablets.
In the Coronary Drug Project, a large study of post myocardial infarction of patients treated for 5 years with clofibrate, there was no difference in mortality seen between the clofibrate group and the placebo group. There was however, a difference in the rate of cholelithiasis and cholecystitis requiring surgery between the two groups (3.0% vs. 1.8%). In a study conducted by the World Health Organization (WHO), 5000 subjects without known coronary artery disease were treated with placebo or clofibrate for 5 years and followed for an additional one year. There was a statistically significant, higher age − adjusted all-cause mortality in the clofibrate group compared with the placebo group (5.70% vs. 3.96%, p = < 0.01). Excess mortality was due to a 33% increase in non-cardiovascular causes, including malignancy, post-cholecystectomy complications, and pancreatitis. This appeared to confirm the higher risk of gallbladder disease seen in clofibrate- treated patients studied in the Coronary Drug Project. The Helsinki Heart Study was a large (n=4081) study of middle-aged men without a history of coronary artery disease. Subjects received either placebo or gemfibrozil for 5 years, with a 3.5 year open extension afterward. Total mortality was numerically higher in the gemfibrozil randomization group but did not achieve statistical significance (p = 0.19, 95% confidence interval for relative risk G:P = .91-1.64). Although cancer
deaths trended higher in the gemfibrozil group (p = 0.11), cancers (excluding basal cell carcinoma) were diagnosed with equal frequency in both study groups. Due to the limited size of the study, the relative risk of death from any cause was not shown to be different than that seen in the 9 year follow-up data from World Health Organization study (RR=1.29).
A secondary prevention component of the Helsinki Heart Study enrolled middle-aged men excluded from the primary prevention study because of known or suspected coronary heart disease. Subjects received gemfibrozil or placebo for 5 years. Although cardiac deaths trended higher in the gemfibrozil group, this was not statistically significant (hazard ratio 2.2, 95% confidence interval: 0.94-5.05). The rate of gallbladder surgery was not statistically significant between study groups, but did trend higher in the gemfibrozil group, (1.9% vs. 0.3%, p = 0.07).
· Skeletal Muscle
Fibrates increase the risk for myopathy and have been associated with rhabdomyolysis. The risk for serious muscle toxicity appears to be increased in elderly patients and in patients with diabetes, renal insufficiency, or hypothyroidism.
Myopathy should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevations of creatine phosphokinase (CPK) levels. Patients should be advised to report promptly unexplained muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever. CPK levels should be assessed in patients reporting these symptoms, and Fenofibrate Tablets therapy should be discontinued if markedly elevated CPK levels occur or myopathy/myositis is suspected or diagnosed.
Data from observational studies indicate that the risk for rhabdomyolysis is increased when fibrates, in particular gemfibrozil, are co-administered with an HMG-CoA reductase inhibitor (statin). The combination should be avoided unless the benefit of further alterations in lipid levels is likely to outweigh the increased risk of this drug combination Cases of myopathy, including rhabdomyolysis, have been reported with fenofibrates coadministered
With colchicine, and caution should be exercised when prescribing fenofibrate with colchicine.
· Liver Function
Fenofibrate at doses equivalent to 96 mg to 145 mg Fenofibrate Tablets per day has been associated with increases in serum transaminases [AST (SGOT) or ALT (SGPT)]. In a pooled analysis of 10 placebo-controlled trials, increases to > 3 times the upper limit of normal occurred in 5.3% of patients taking fenofibrate versus 1.1% of patients treated with placebo.
When transaminase determinations were followed either after discontinuation of treatment or during continued treatment, a return to normal limits was usually observed. The incidence of increases in transaminases related to fenofibrate therapy appear to be dose related. In an 8-week dose-ranging study, the incidence of ALT or AST elevations to at least three times the upper limit of normal was 13% in patients receiving dosages equivalent to 96 mg to 145 mg Fenofibrate Tablets per day and was 0% in those receiving dosages equivalent to 48 mg or less Fenofibrate Tablets per day, or placebo. Hepatocellular, chronic active and cholestatic hepatitis associated with fenofibrate therapy have been reported after exposures of weeks to several years. In extremely rare cases, cirrhosis has been reported in association with chronic active hepatitis. Baseline and regular periodic monitoring of liver function, including serum ALT (SGPT) should be performed for the duration of therapy with Fenofibrate Tablets, and therapy discontinued if enzyme levels persist above three times the normal limit.
· Serum Creatinine
Elevations in serum creatinine have been reported in patients on fenofibrate. These elevations tend to return to baseline following discontinuation of fenofibrate. The clinical significance of these observations is unknown. Monitor renal function in patients with renal impairment taking Fenofibrate Tablets. Renal monitoring should also be considered for patients taking Fenofibrate Tablets at risk for renal insufficiency such as the elderly and patients with diabetes.
· Cholelithiasis
Fenofibrate, like clofibrate and gemfibrozil, may increase cholesterol excretion into the bile, leading to Cholelithiasis. If Cholelithiasis is suspected, gallbladder studies are indicated. Fenofibrate Tablets therapy should be discontinued if gallstones are found.
· Coumarin Anticoagulants
Caution should be exercised when coumarin anticoagulants are given in conjunction with Fenofibrate Tablets because of the potentiation of coumarin-type anticoagulant effects in prolonging the Prothrombin Time/International Normalized Ratio (PT/INR). To prevent bleeding complications,
frequent monitoring of PT/INR and dose adjustment of the anticoagulant are recommended until PT/INR has stabilized.
· Pancreatitis
Pancreatitis has been reported in patients taking fenofibrate, gemfibrozil, and clofibrate. This occurrence may represent a failure of efficacy in patients with severe hypertriglyceridemia, a direct drug effect, or a secondary phenomenon mediated through biliary tract stone or sludge formation with obstruction of the common bile duct.
· Hematologic Changes
Mild to moderate hemoglobin, haematocrit, and white blood cell decreases have been observed in patients following initiation of fenofibrate therapy. However, these levels stabilize during long term administration. Thrombocytopenia and agranulocytosis have been reported in individuals treated with fenofibrate. Periodic monitoring of red and white blood cell counts are recommended during the first 12 months of Fenofibrate Tablets administration.
· Hypersensitivity Reactions
Acute Hypersensitivity
Anaphylaxis and angioedema have been reported postmarketing with fenofibrate. In some cases, reactions were life-threatening and required emergency treatment. If a patient develops signs or symptoms of an acute hypersensitivity reaction, advise them to seek immediate medical attention and discontinue fenofibrate.
Delayed Hypersensitivity
Severe cutaneous adverse drug reactions (SCAR), including Stevens-Johnson syndrome, toxic epidermal necrolysis, and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have been reported postmarketing, occurring days to weeks after initiation of fenofibrate. The cases of DRESS were associated with cutaneous reactions (such as rash or exfoliative dermatitis) and a combination of eosinophilia, fever, systemic organ involvement (renal, hepatic, or respiratory). Discontinue fenofibrate and treat patients appropriately if SCAR is suspected.
· Venothromboembolic Disease
In the Field trial, pulmonary embolus (PE) and deep vein thrombosis (DVT) were observed at higher rates in the fenofibrate- than the placebo-treated group. Of 9,795 patients enrolled in FIELD, there were 4,900 in the placebo group and 4,895 in the fenofibrate group. For DVT, there were 48 events (1%) in the placebo group and 67 (1%) in the fenofibrate group (p = 0.074); and for PE, there were 32 (0.7%) events in the placebo group and 53 (1%) in the fenofibrate group (p
= 0.022). In the Coronary Drug Project, a higher proportion of the clofibrate group experienced
definite or suspected fatal or nonfatal pulmonary embolism or thrombophlebitis than the placebo group (5.2% vs. 3.3% at five years; p < 0.01).
Children and adolescents
Fenofibrate Tablets 48mg and 145mg should not be used in children. There are no data demonstrating efficacy or safety of fenofibrate Tablets in children.
Other medicines and Fenofibrate Tablets 48mg and 145mg
· Coumarin Anticoagulants
Potentiation of coumarin-type anticoagulant effects has been observed with prolongation of the PT/INR. Caution should be exercised when coumarin anticoagulants are given in conjunction with Fenofibrate Tablets. The dosage of the anticoagulants should be reduced to maintain the PT/INR at the desired level to prevent bleeding complications. Frequent PT/INR determinations are advisable until it has been definitely determined that the PT/INR has stabilized [see Warnings and Precautions (5.6)].
· Immunosuppressant’s
Immunosuppressants such as cyclosporine and tacrolimus can produce nephrotoxicity with decreases in creatinine clearance and rises in serum creatinine, and because renal excretion is the primary elimination route of fibrate drugs including Fenofibrate Tablets, there is a risk that an interaction will lead to deterioration of renal function. The benefits and risks of using (fenofibrate tablets) with immunosuppressant’s and other potentially nephrotoxic agents should be carefully considered, and the lowest effective dose employed and renal function monitored.
· Bile Acid Binding Resins
Since bile acid binding resins may bind other drugs given concurrently, patients should take Fenofibrate Tablets at least 1 hour before or 4 to 6 hours after a bile acid binding resin to avoid impeding its absorption.
· Colchicine
Cases of myopathy, including rhabdomyolysis, have been reported with fenofibrate coadministered with colchicine, and caution should be exercised when prescribing fenofibrate with colchicine.

Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
Adverse events reported by 2% or more of patients treated with fenofibrate (and greater than placebo) during the double-blind, placebo-controlled trials, regardless of causality, are listed in Table 1 below. Adverse events led to discontinuation of treatment in 5.0% of patients treated with fenofibrate and in 3.0% treated with placebo. Increases in liver function tests were the most frequent events, causing discontinuation of fenofibrate treatment in 1.6% of patients in double blind trials.

Postmarketing Experience
The following adverse reactions have been identified during post approval use of fenofibrate. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: myalgia, rhabdomyolysis, pancreatitis, acute renal failure, muscle spasm, hepatitis, cirrhosis, anemia, arthralgia, decreases in hemoglobin, decreases in haematocrit, white blood cell decreases, asthenia, severely depressed HDL-cholesterol levels, and interstitial lung disease. Photosensitivity reactions have occurred days to months after initiation; in some of these cases, patients reported a prior photosensitivity reaction to ketoprofen

تنتمي أقراص ليبوفريت إلى مجموعة من الأدوية تسمى فيبرات.
· فرط كوليسترول الدم الأولي أو خلل شحوم الدم المختلط
يتم وصف أقراص ليبوفريت كعلاج مساعد للنظام الغذائي لتخفيض نسبة الكوليسترول البروتين الدهني المنخفض الكثافة (LDL-C) والكوليسترول الكلي (Total- C) والدهون الثلاثية والبروتينات البروتينية الدهنية (Apo B)، وزيادة الكوليسترول الدهني عالي الكثافة -C) في المرضى البالغين المصابين بفرط كوليسترول الدم الأولي أو خلل الدهون في الدم.
· فرط الدهون الثلاثية الشديدة
يتم وصف أقراص ليبوفريت كعلاج مساعد للنظام الغذائي لعلاج المرضى البالغين المصابين بارتفاع نسبة الدهون الثلاثية الشديدة. إن تحسين التحكم في نسبة السكر في الدم لدى مرضى السكري الذين يظهرون صيام الكيلومكرونات في الدم الصائم عادةً ما يتجنب الحاجة إلى التدخل الدوائي. مستويات مرتفعة بشكل ملحوظ من الدهون الثلاثية في الدم (على سبيل المثال> 2000 ملغ / ديسيلتر) قد تزيد من خطر الإصابة بالتهاب البنكرياس. لم يكن تأثير علاج فينوفايبرات على تقليل هذا الخطر درس بشكل كاف.
· القيود المهمة على استخدام فينوفايبرات بجرعة تعادل 145 ملغم من ليبوفريت أقراص لم تُظهر أنها تقلل من معدلات المرض ووفيات أمراض الشريان التاجي في تجربة عشوائية ذات شواهد كبيرة لمرضى داء السكري من النوع 2.
وتستخدم هذه الأدوية لخفض مستويات الدهون في الدم، على سبيل المثال المعروفة باسم الدهون الثلاثية.
يستخدم ليبوفريت بالتعاون مع نظام غذائي يعمل على خفض الدهون وغيرها من العلاجات غير الدوائية مثل ممارسة الرياضة والحد من الوزن لخفض مستويات الدهون في الدم.
ويمكن استخدام ليبوفريت عندما تكون المنتجات الطبية الأخرى [ستاتين] غير مناسبة، من أجل الحد من خطر حدوث مشاكل في القلب بين الأشخاص ذوي الخطورة العالية وأولئك الذين يعانون من ارتفاع “نسبة الكوليسترول الضار".
يجب على المرضى الالتزام بنظام غذائي مناسب لخفض الدهون قبل تناول ليبوفريت أقراص، ويجب أن يستمر هذا النظام الغذائي أثناء العلاج بتناول ليبوفريت أقراص. ويمكن تناول ليبوفريت أقراص دون اعتبار للوجبات.
العلاج الأولي لاضطرابات الدهون في الدم هو علاج غذائي محدد لنوع البروتين الدهني الغير طبيعي. قد يكون وزن الجسم الزائد والإفراط في تناول الكحوليات من العوامل التي تؤدي إلى ارتفاع الدهون الثلاثية وينبغي معالجة ذلك قبل أي علاج دوائي. يمكن أن يكون إجراءً التمرينات البدنية مساعدًا مهمًا. الأمراض التي تسهم في فرط دهون الدم، مثل قصور الغدة الدرقية أو داء السكري، يجب التحقق منها وعلاجها بشكل مناسب. في بعض الأحيان يرتبط العلاج بالأستروجين ومدرّات البول الثيازيدية وحاصرات بيتا بالارتفاعات الهائلة لنسبة الدهون الثلاثية في البلازما، خاصةً في الأشخاص الذين يعانون من فرط الدهون الثلاثية العائلي. في مثل هذه الحالات، قد يؤدي إيقاف العامل المسبب لارتفاع الدهون الثلاثية في الدم إلى تجنب الحاجة إلى علاج دوائي محدد لفرط الدهون الثلاثية.
يجب مراقبة مستويات الدهون بشكل دوري مع الأخذ في الاعتبار لتقليل جرعة ليبوفريت أقراص إذا انخفضت مستويات الدهون بشكل كبير عن النطاق المستهدف.
يجب سحب العلاج في المرضى الذين ليس لديهم استجابة كافية بعد شهرين من العلاج بتناول الجرعة القصوى الموصي بها والمقدرة بتركيز 145 ملغم مرة واحدة يوميًا.
التحذيرات والاحتياطات
· الحالات المرضية وحالات الوفيات الناتجة عن أمراض القلب التاجية
لم يتم إثبات تأثير تناول ليبوفريت أقراص على نسبة الحالات المرضية وحالات الوفيات الناتجة عن أمراض القلب التاجية وكذلك حالات الوفيات الناتجة عن أمراض القلب الغير مرتبط بالمشاكل الوعائية.
كانت تجربة العمل للتحكم في مخاطر الإصابة بأمراض القلب والأوعية الدموية في مرضى السكري مع ارتفاع نسبة الدهون (ACCORD Lipid) عبارة عن دراسة عشوائية خاضعة بمرجعية الدواء الوهمي أجريت على 5518 مريضًا من المصابين بداء السكري من النوع 2 ويتناولون علاج من مجموعة ستاتين حيث يتناولون فينوفايبرات. وكان متوسط مدة المتابعة 4.7 سنوات. أظهرت النتائج أن العلاج بتناول فينوفايبرات بالإضافة إلى مركب الستاتين نسب منخفضة بنسبة 8٪ في المخاطر الأولية في الآثار الجانبية القلبية الوعائية الضارة (MACE)، وتتمثل في احتشاء عضلة القلب غير المميت والسكتة الدماغية غير القاتلة ووفيات أمراض القلب والأوعية الدموية (نسبة الخطر [HR] 0.92، 95 ٪ CI 0.79-1.08) (p = 0.32) بالمقارنة مع الستاتين مستقلا. في تحليل مجموعة فرعية بين الجنسين، كانت نسبة الخطر لحالات MACE في الرجال الذين يتلقون العلاج المركب مقابل الستاتين مستقلا 0.82 (95 ٪ CI 0.69-0.99)، ونسبة الخطر لحالات MACE في النساء اللائي يتلقين العلاج المركب مقابل الستاتين مستقلا كانت 1.38 (95 ٪ CI 0،98-1،94) (التفاعل p = 0.01).
أهمية الدراسات السريرية لهذه النتيجة الفرعية غير واضحة. كانت دراسة تدرس آثار العلاج بتناول فايبرات على المدى الطويل على أمراض القلب والشرايين (FIELD) عبارة عن دراسة عشوائية بمرجعية الدواء الوهمي استمرت 5 سنوات وشملت 9795 مريضاً مصابين بداء السكري من النوع 2 عولجوا بتناول فينوفايبرات. أظهر فينوفايبرات انخفاضًا نسبيًا غير مهم بنسبة 11٪ في النتيجة الأولية لأحداث أمراض القلب التاجية (نسبة الخطورة [HR] 0.89، 95٪ CI 0.75-1.05، p = 0.16) وتقليل كبير بنسبة 11٪ في النتيجة الثانوية الإجمالية أحداث أمراض القلب والأوعية الدموية (HR 0.89 [0.80-0.99]، p = 0.04). كان هناك 11 ٪ غير مهم (HR 1.11 [0.95، 1.29]، p = 0.18) و19 ٪ (HR 1.19 [0.90، 1.57]، p = 0.22) زيادة في الوفيات الكلية وأمراض القلب التاجية، على التوالي، مع تناول فينوفايبرات بالمقارنة مع الدواء الوهمي.
بسبب التشابهات الكيميائية والصيدلانية والسريرية بين ليبوفريت أقراص وكلوفيبيرات وجيمفيبروزيل، فإن النتائج السلبية في 4 دراسات سريرية بمرجعية الدواء الوهمي كبيرة وقد تنطبق أيضًا على ليبوفريت أقراص.
في مشروع عقاقير الشريان التاجي، وهي دراسة كبيرة عن احتشاء عضلة القلب في المرضى الذين عولجوا لمدة 5 سنوات بتناول كلوفيبرات، لم يكن هناك فرق في الوفيات التي لوحظت بين مجموعة كلوفيبرات ومجموعة الدواء الوهمي. ومع ذلك، كان هناك اختلاف في معدل تكون الحصوات الصفراوية والتهاب المرارة التي تتطلب جراحة بين المجموعتين (3.0 ٪ مقابل 1.8 ٪). في دراسة أجرتها منظمة الصحة العالمية (WHO)، عولج 5000 شخص بدون مرض الشريان التاجي المعروف بالدواء الوهمي وكلوفيبرات لمدة 5 سنوات وتم متابعتهم لمدة عام إضافي. كان هناك دلالة إحصائية على وفيات بمعدلات أعلى حسب العمر الزائد في المجموعة كلوفيبرات مقارنة مع مجموعة الدواء الوهمي (5.70 ٪ مقابل 3.96 ٪، P = <0.01). كان معدل الوفيات الزائدة بسبب زيادة بنسبة 33 ٪ في الأسباب غير القلبية الوعائية، بما في ذلك الأورام الخبيثة، ومضاعفات استئصال المرارة، والتهاب البنكرياس. ويبدو أن هذا يؤكد ارتفاع خطر الإصابة بمرض المرارة في المرضى الذين عولجوا بتناول كلوفيبرات الذين تمت دراستهم في مشروع عقاقير الشريان التاجي. كانت دراسة هلسنكي للقلب دراسة كبيرة (n = 4081) على الرجال في منتصف العمر دون تاريخ مرضي بالشريان التاجي. تم تناول الدواء الوهمي وجيمفيبروزيل لمدة 5 سنوات، مع تمديد مفتوح للمتابعة لمدة 3.5 سنوات بعد ذلك. وكان إجمالي الوفيات أعلى عدديا في المجموعة العشوائية جيمفيبروزيل لكنه لم يحقق دلالة إحصائية (P = 0.19، فاصل الثقة 95 ٪ للمخاطر النسبية G: P = .91-1.64). على الرغم من أن حالات الوفاة بالسرطان تتجه نحو الأعلى في مجموعة جيمفيبروزيل (p = 0.11)، فقد تم تشخيص السرطانات (باستثناء سرطان الخلايا القاعدية) بمعدلات متساويةٍ في مجموعتي الدراسة. نظرًا للحجم المحدود للدراسة، لم يكن الخطر النسبي للوفاة من أي سبب مختلفًا عن ذلك الذي ظهر في بيانات المتابعة لمدة 9 سنوات من دراسة منظمة الصحة العالمية (RR = 1.29).
عنصر الوقاية الثانوية في دراسة هلسنكي للقلب على الرجال المسجلين في منتصف العمر المستبعدين من دراسة الوقاية الأولية بسبب مرض القلب التاجي المعروف أو المشتبه به. تم تناول الدواء الوهمي وجيمفيبروزيل لمدة 5 سنوات. على الرغم من أن الوفيات القلبية تتجه نحو الأعلى في مجموعة جيمفيبروزيل، إلا أن هذا لم يكن ذو دلالة إحصائية (نسبة الخطر 2.2، فاصل الثقة 95٪: 0.94-5.05). لم يكن معدل جراحة المرارة ذات دلالة إحصائية بين مجموعات الدراسة، ولكنها كانت أعلى في المجموعة جيمفيبروزيل، (1.9 ٪ مقابل 0.3 ٪، P = 0.07).
· العضلات الهيكلية
تزيد الفايبرات من خطر الإصابة بالاعتلال العضلي وترتبط بحالات انحلال الربيدات. يبدو أن خطر التسمم العضلي الخطير يزداد عند المرضى المسنين وفي مرضى السكري أو القصور الكلوي أو قصور الغدة الدرقية.
يجب النظر إلى الاعتلال العضلي لدى أي مريض مصاب بألم عضلي منتشر، أو لين عضلي أو ضعف، و / أو ارتفاعات ملحوظة لمستويات فسفوكيناز الكرياتين (CPK). يجب أن ينصح المرضى بالإبلاغ الفوري عن آلام العضلات، أو لين أو الضعف غير المبررة، خاصةً إذا كان مصحوبًا بتوعك أو حمى. يجب تقييم مستويات CPK في المرضى الذين يبلغون عن هذه الأعراض، ويجب إيقاف علاج ليبوفريت أقراص إذا حدث ارتفاع مستويات من CPK بشكل ملحوظ أو كان يشتبه أو يتم تشخيص التهاب عضلي / عضلي.
تشير البيانات المستقاة من الدراسات القائمة على الملاحظة إلى أن خطر انحلال الربيدات يزداد عندما يتم استخدام الفايبرات، وخاصة الجيمبروزيل، مع مثبط إنزيم HMG-CoA (الستاتين). يجب تجنب المزيج ما لم يكن من المحتمل أن تفوق فائدة إجراء المزيد من التعديلات في مستويات الدهون على زيادة خطر هذه التركيبة الدوائية. تم الإبلاغ عن حالات اعتلال عضلي، بما في ذلك انحلال الربيدات، باستخدام فينوفايبرات يشترك فيها مع كولشيسين، ويجب توخي الحذر عند وصف فينوفايبرات مع الكولشيسين.

ارتبط تناول فينوفايبرات بجرعات تعادل 96 ملغم إلى 145 ملغم ليبوفريت أقراص يوميًا بزيادة في إنزيمات ناقلات الأمين في الدم [AST (SGOT) أو ALT (SGPT)]. في تحليل مُجمَّع لـ 10 تجارب تم المقارنة فيها بالدواء الوهمي، ارتفع الحد الأعلى الطبيعي إلى 3 أضعاف في 5.3٪ من المرضى الذين يتناولون فينوفايبرات مقابل 1.1٪ من المرضى الذين عولجوا بالدواء الوهمي.
عندما تم متابعة نسبة إنزيمات ناقلات الأمين في الدم إما بعد توقف العلاج أو أثناء العلاج المستمر، لوحظت عادة العودة إلى الحدود الطبيعية. يبدو أن نسبة حدوث الزيادات في إنزيمات ناقلات الأمين في الدم المرتبطة بعلاج فينوفايبرات مرتبطة بالجرعة. في دراسة على مدى جرعة لمدة 8 أسابيع، كانت نسبة حدوث ارتفاعات ALT أو AST إلى ثلاثة أضعاف الحد الأعلى الطبيعي 13٪ في المرضى الذين يتناولون جرعات تعادل 96 ملغم إلى 145 ملغم ليبوفريت أقراص يوميًا وكان 0٪ في أولئك الذين يتناولون جرعات تعادل 48 ملغم أو أقل من ليبوفريت أقراص في اليوم، أو الدواء الوهمي. تم الإبلاغ عن التهاب الكبد الخلوي، التهاب الكبد المزمن النشط المرتبط بالعلاج بتناول الفينوفايبرات بعد التعرض لعدة أسابيع إلى عدة سنوات. في حالات نادرة للغاية، تم الإبلاغ عن تليف الكبد بالاشتراك مع التهاب الكبد النشط المزمن. يجب إجراء متابعة والرصد الدوري المنتظم لوظائف الكبد، بما في ذلك ALT (SGPT) في الدم أثناء مدة العلاج مع ليبوفريت أقراص، وتوقف المعالجة إذا استمرت مستويات الإنزيم فوق ثلاثة أضعاف الحد الطبيعي.
· الكرياتينين في الدم
تم الإبلاغ عن الارتفاعات في نسبة الكرياتينين في الدم في المرضى الذين يتناولون فينوفايبرات. هذه الارتفاعات تميل إلى العودة إلى المعدلات الطبيعية بعد توقف فينوفايبرات. الأهمية السريرية لهذه الملاحظات غير معروفة. يجب مراقبة وظائف الكلى في المرضى الذين يعانون من القصور الكلوي مع تناول ليبوفريت أقراص. كما يجب مراعاة ومراقبة الكلى للمرضى الذين يتناولون ليبوفريت أقراص ولديهم خطر الإصابة بقصور كلوي مثل كبار السن ومرضى السكري.
· الحصاة الصفراوية
فينوفايبرات، مثل كلوفيبرات وجمفبروزيل، قد تزيد إفراز الكولسترول في الصفراء، مما يؤدي إلى تكون حصوات صفراوية. إذا كان يشتبه في تكون حصوات صفراوية، فيجب فحص المرارة. ويجب وقف العلاج بتناول ليبوفريت أقراص إذا تم الكشف عن حصى في المرارة.
· مضادات التخثر (الكومارين)
يجب توخي الحذر عند استخدام مضادات التخثر من نوع الكومارين بالتزامن مع ليبوفريت أقراص بسبب تقوية تأثيرات مضادات التخثر من النوع الكومارين في إطالة فترة البروثرومبين / النسبة الطبيعية الدولية (PT / INR). لمنع حدوث مضاعفات النزيف، يوصى بمراقبة متكررة لنسبة PT / INR وتعديل جرعة مضاد التخثر حتى تستقر نسبة PT / INR.
· التهاب البنكرياس
تم الإبلاغ عن حالات التهاب البنكرياس في المرضى الذين يتناولون فينوفايبرات وجيمفيبروزيل وكلوفيبرات. قد يمثل هذا الحدث فشلًا في الفعالية لدى مرضى الذين يعانون من فرط الدهون الثلاثية الشديدة، أو تأثير دوائي مباشر، أو ظاهرة ثانوية تتوسط من خلال حصاة القناة الصفراوية أو تكوين الترسيبات مع انسداد القناة الصفراوية الشائع.
· التغييرات الدموية
لوحظت انخفاضات خفيفة إلى معتدلة في الهيموجلوبين، الهيماتوكريت، وانخفاض خلايا الدم البيضاء في المرضى بعد بدء العلاج بتناول فينوفايبرات. ومع ذلك، فإن هذه المستويات تستقر خلال الاستخدام طويلة الأجل. تم الإبلاغ عن نقص الصفيحات وندرة المحببات في الأفراد الذين عولجوا باستخدام الفينوفايبرات. يوصى بمراقبة دورية لتعداد خلايا الدم الحمراء والبيضاء خلال الأشهر الـ 12 الأولى من تناول ليبوفريت أقراص.
· تفاعلات فرط الحساسية
فرط الحساسية الحاد
تم الإبلاغ عن الحساسية المفرطة وذمة وعائية بعد تسويق فينوفايبرات. في بعض الحالات، كانت ردود الفعل تهدد الحياة وتتطلب العلاج في حالات الطوارئ. إذا ظهر على المريض علامات أو أعراض رد فعل فرط الحساسية الحاد، وتقديم المشورة لهم للحصول على عناية طبية فورية وتوقف فينوفايبرات.
فرط الحساسية المتأخر
تم الإبلاغ عن التفاعلات الجانبية الضارة والحادة (SCAR)، بما في ذلك متلازمة ستيفنز-جونسون، وتنخر البشرة عن طريق الجلد السام، وردود الفعل الدوائية مع فرط الحمضات والأعراض الجهازية (DRESS)، في مرحلة ما بعد التسويق، تحدث بعد أيام إلى أسابيع من بدء العلاج بتناول فينوفايبرات. ارتبطت حالات DRESS بتفاعلات جلدية (مثل طفح جلدي أو التهاب جلدي تقشري) ومجموعة من فرط الحمضات، حمى، أعراض جانبية لأعضاء أخرى (كلوي، كبدي، أو تنفسي). التوقف عن فينوفايبرات وعلاج المرضى بشكل مناسب إذا كان يشتبه في SCAR.
· مرض انسداد الشرايين
في التجربة الميدانية، لوحظ وجود انسداد رئوي (PE) وتجلط الأوردة العميقة (DVT) بمعدلات أعلى مع تناول فينوفايبرات - من المجموعة التي عولجت بالعلاج الوهمي. من بين 9795 مريض مسجلين في FIELD، كان هناك 4900 مريض الذين تناولوا مجموعة العلاج الوهمي و4995 مريض في مجموعة الذين تناولوا فينوفايبرات. ل DVT، كان هناك 48 حدثا (1 ٪) في المجموعة الثانية و67 (1 ٪) في مجموعة فينوفايبرات (p = 0.074)؛ وبالنسبة لـ PE، كان هناك 32 (0.7٪) من الأحداث في مجموعة الدواء الوهمي و53 (1٪) في مجموعة فينوفايبرات (p = 0.022). في مشروع عقاقير الشريان التاجي، شهدت نسبة أعلى من مجموعة كوليفايبرات انسدادًا رئويًا قاتلًا أو غير مميت أو مشتبه به من انسداد رئوي أو التهاب الوريد الخثاري مقارنةً بالمجموعة الثانية (5.2٪ مقابل 3.3٪ في خمس سنوات ؛ P <0.01).
الأطفال والمراهقين
يجب عدم استخدام ليبوفريت أقراص 48 ملغم و145 ملغم في الأطفال. لا توجد بيانات توضح فعالية أو سلامة ليبوفريت أقراص في الأطفال
تناول أدوية أخرى مع ليبوفريت أقراص:
· مضادات التخثر (الكومارين)
قد لوحظ تعزيز آثار مضادات التخثر من نوع الكومارين مع إطالة PT / INR. يجب توخي الحذر عند إعطاء مضادات التخثر الكومارين بالتزامن مع ليبوفريت أقراص. يجب تقليل جرعة مضادات التخثر للحفاظ على PT / INR في المستوى المطلوب لمنع مضاعفات النزيف. يُنصح بتحديد اختبارات PT / INR المتكررة إلى أن يتقرر بالتأكيد أن PT / INR قد استقرت [انظر التحذيرات والاحتياطات (5.6)].
· المثبطات المناعية
المثبطات المناعية مثل السيكلوسبورين والتكروليم يمكن أن تنتج سمية كلوية مع انخفاض في تصفية الكرياتينين وارتفاع في الكرياتينين في الدم، ولأن إفراز الكلى هو طريق الأساسي للتخلص من عقاقير الفايبرات بما في ذلك ليبوفريتومات، هناك خطر من أن التفاعل قد يؤدي إلى تدهور وظائف الكلى. ينبغي النظر بعناية في فوائد ومخاطر استخدام (ليبوفريت أقراص) مع مثبطات المناعة وغيرها من العوامل التي يحتمل أن تكون سامة للأمعاء، ويجب مراقبة أقل جرعة فعالة ومراقبة وظائف الكلى.
· راتنجات ربط (محتجزات) حمض الصفراء
نظرًا لأن راتنجات حمض الصفراء قد تربط الأدوية الأخرى التي تعطى بشكل متزامن، يجب على المرضى تناول ليبوفريت أقراص قبل ساعة أو 4 إلى 6 ساعات على الأقل من تناول راتنج ربط حمض الصفراء لتجنب إعاقة امتصاصه.
· الكوليشسين
تم الإبلاغ عن حالات اعتلال عضلي، بما في ذلك انحلال الربيدات، باستخدام فينوفايبرات مع الكوليشسين، ويجب توخي الحذر عند وصف فينوفايبرات مع كوليشسين.

1.1.1 Primary Hypercholesterolemia or Mixed Dyslipidemia
Fenofibrate Tablets is indicated as adjunctive therapy to diet to reduce elevated low-density lipoprotein cholesterol (LDL-C), total cholesterol (Total-C), Triglycerides and apolipoprotein B (Apo B), and to increase high-density lipoprotein cholesterol (HDL-C) in adult patients with primary hypercholesterolemia or mixed dyslipidemia.
1.1.2 Severe Hypertriglyceridemia
Fenofibrate Tablets is also indicated as adjunctive therapy to diet for treatment of adult patients with severe hypertriglyceridemia. Improving glycemic control in diabetic patients showing fasting chylomicronemia will usually obviate the need for pharmacologic intervention.
Markedly elevated levels of serum triglycerides (e.g. > 2,000 mg/dL) may increase the risk of developing pancreatitis. The effect of fenofibrate therapy on reducing this risk has not been adequately studied
1.1.3 Important Limitations of Use
Fenofibrate at a dose equivalent to 145 mg of Fenofibrate Tablets was not shown to reduce coronary heart disease morbidity and mortality in a large, randomized controlled trial of patients with type 2 diabetes mellitus
Patients should be placed on an appropriate lipid-lowering diet before receiving Fenofibrate Tablets, and should continue this diet during treatment with Fenofibrate Tablets. Fenofibrate Tablets can be given without regard to meals.
The initial treatment for dyslipidemia is dietary therapy specific for the type of lipoprotein abnormality. Excess body weight and excess alcoholic intake may be important factors in hypertriglyceridemia and should be addressed prior to any drug therapy. Physical exercise can be an important ancillary measure. Diseases contributory to hyperlipidemia, such as hypothyroidism or diabetes mellitus should be looked for and adequately treated. Estrogen therapy, thiazide diuretics and beta-blockers, are sometimes associated with massive rises in plasma triglycerides,
Especially in subjects with familial hypertriglyceridemia. In such cases, discontinuation of the specific etiologic agent may obviate the need for specific drug therapy of hypertriglyceridemia. Lipid levels should be monitored periodically and consideration should be given to reducing the dosage of Fenofibrate Tablets if lipid levels fall significantly below the targeted range.
Therapy should be withdrawn in patients who do not have an adequate response after two months of treatment with the maximum recommended dose of 145 mg once daily 2.2 Primary Hypercholesterolemia or Mixed Dyslipidemia The initial dose of Fenofibrate Tablets is 145 mg once daily.
4.2.1 Severe Hypertriglyceridemia
The initial dose is 48 to 145 mg per day. Dosage should be individualized according to patient Response, and should be adjusted if necessary following repeat lipid determinations at 4 to 8 week intervals. The maximum dose is 145 mg once daily.
4.2.2 Impaired Renal Function
Treatment with Fenofibrate Tablets should be initiated at a dose of 48 mg per day in patients having mild to moderately impaired renal function, and increased only after evaluation of the effects on renal function and lipid levels at this dose. The use of Fenofibrate Tablets should be avoided in patients with severe renal impairment.
4.2.3 Geriatric Patients
Dose selection for the elderly should be made on the basis of renal function.
The effect of Fenofibrate Tablets on coronary heart disease morbidity and mortality and noncardiovascular mortality has not been established.
The Action to Control Cardiovascular Risk in Diabetes Lipid (ACCORD Lipid) trial was a Randomized placebo-controlled study of 5518 patients with type 2 diabetes mellitus on background statin therapy treated with fenofibrate. The mean duration of follow-up was 4.7 years. Fenofibrate plus statin combination therapy showed a non-significant 8% relative risk reduction in the primary outcome of major adverse cardiovascular events (MACE), a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular disease death (hazard ratio [HR] 0.92, 95% CI 0.79-1.08) (p=0.32) as compared to statin monotherapy. In a gender subgroup analysis, the hazard ratio for MACE in men receiving combination therapy versus statin monotherapy was 0.82 (95% CI 0.69-0.99), and the hazard ratio for MACE in women
Receiving combination therapy versus statin monotherapy was 1.38 (95% CI 0.98-1.94) (interaction p=0.01). The clinical significance of this subgroup finding is unclear. The Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study was a 5-year randomized, placebo-controlled study of 9795 patients with type 2 diabetes mellitus treated with fenofibrate. Fenofibrate demonstrated a non-significant 11% relative reduction in the primary outcome of coronary heart disease events (hazard ratio [HR] 0.89, 95% CI 0.75-1.05, p=0.16) and a significant 11% reduction in the secondary outcome of total cardiovascular disease events (HR 0.89 [0.80-0.99], p=0.04). There was a non-significant 11% (HR 1.11 [0.95, 1.29], p=0.18) and 19% (HR 1.19 [0.90, 1.57], p=0.22) increase in total and coronary heart disease mortality, respectively, with fenofibrate as compared to placebo.
Because of chemical, pharmacological, and clinical similarities between Fenofibrate Tablets (fenofibrate tablets), clofibrate, and gemfibrozil, the adverse findings in 4 large randomized, placebo controlled Clinical studies with these other fibrate drugs may also apply to Fenofibrate Tablets.
In the Coronary Drug Project, a large study of post myocardial infarction of patients treated for 5 Years with clofibrate, there was no difference in mortality seen between the clofibrate group and the placebo group. There was however, a difference in the rate of Cholelithiasis and cholecystitis
Requiring surgery between the two groups (3.0% vs. 1.8%) In a study conducted by the World Health Organization (WHO), 5000 subjects without known coronary artery disease were treated with placebo or clofibrate for 5 years and followed for an additional one year. There was a statistically significant, higher age − adjusted all-cause mortality in the clofibrate group compared with the placebo group (5.70% vs. 3.96%, p = < 0.01). Excess mortality was due to a 33% increase in non-cardiovascular causes, including malignancy, post-cholecystectomy complications, and pancreatitis. This appeared to confirm the higher risk of gallbladder disease seen in clofibrate-treated patients studied in the Coronary Drug Project.
The Helsinki Heart Study was a large (n=4081) study of middle-aged men without a history of coronary artery disease. Subjects received either placebo or gemfibrozil for 5 years, with a 3.5 year open extension afterward. Total mortality was numerically higher in the gemfibrozil randomization group but did not achieve statistical significance (p = 0.19, 95% confidence interval for relative risk G:P = .91-1.64). Although cancer deaths trended higher in the gemfibrozil group (p = 0.11), cancers (excluding basal cell carcinoma) were diagnosed with equal frequency in both study groups. Due to the limited size of the study, the relative risk of death from any cause was not shown to be different than that seen in the 9 year follow-up data from World Health Organization study (RR=1.29).
A secondary prevention component of the Helsinki Heart Study enrolled middle-aged men excluded from the primary prevention study because of known or suspected coronary heart disease. Subjects received gemfibrozil or placebo for 5 years. Although cardiac deaths trended higher in the gemfibrozil group, this was not statistically significant (hazard ratio 2.2, 95%confidence interval: 0.94-5.05). The rate of gallbladder surgery was not statistically significant between study groups, but did trend higher in the gemfibrozil group, (1.9% vs. 0.3%, p = 0.07).
• Skeletal Muscle
Fibrates increase the risk for myopathy and have been associated with rhabdomyolysis. The risk for serious muscle toxicity appears to be increased in elderly patients and in patients with diabetes, renal insufficiency, or hypothyroidism.
Myopathy should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevations of creatine phosphokinase (CPK) levels.
Patients should be advised to report promptly unexplained muscle pain, tenderness or weakness, Particularly if accompanied by malaise or fever. CPK levels should be assessed in patients reporting these symptoms, and Fenofibrate Tablets therapy should be discontinued if markedly elevated CPK levels occur or myopathy/myositis is suspected or diagnosed.
Data from observational studies indicate that the risk for rhabdomyolysis is increased when
Fibrates, in particular gemfibrozil, are co-administered with an HMG-CoA reductase inhibitor (statin). The combination should be avoided unless the benefit of further alterations in lipid levels is likely to outweigh the increased risk of this drug combination Cases of myopathy, including rhabdomyolysis, have been reported with fenofibrates coadministered with colchicine, and caution should be exercised when prescribing fenofibrate with colchicine.
• Liver Function
Fenofibrate at doses equivalent to 96 mg to 145 mg Fenofibrate Tablets per day has been associated with increases in serum transaminases [AST (SGOT) or ALT (SGPT)]. In a pooled analysis of 10 placebo-controlled trials, increases to > 3 times the upper limit of normal occurred in 5.3% of patients taking fenofibrate versus 1.1% of patients treated with placebo.
When transaminase determinations were followed either after discontinuation of treatment or during continued treatment, a return to normal limits was usually observed. The incidence of increases in transaminases related to fenofibrate therapy appear to be dose related. In an 8-week dose-ranging study, the incidence of ALT or AST elevations to at least three times the upper limit of normal was 13% in patients receiving dosages equivalent to 96 mg to 145 mg Fenofibrate Tablets per day and was 0% in those receiving dosages equivalent to 48 mg or less Fenofibrate Tablets per day, or placebo. Hepatocellular, chronic active and cholestatic hepatitis associated with fenofibrate therapy have been reported after exposures of weeks to several years. In extremely rare cases, cirrhosis has been reported in association with chronic active hepatitis. Baseline and regular periodic monitoring of liver function, including serum ALT (SGPT) should be performed for the duration of therapy with Fenofibrate Tablets, and therapy discontinued if enzyme levels persist above three times the normal limit.
• Serum Creatinine
Elevations in serum creatinine have been reported in patients on fenofibrate. These elevations tend to return to baseline following discontinuation of fenofibrate. The clinical significance of these observations is unknown. Monitor renal function in patients with renal impairment taking Fenofibrate Tablets. Renal monitoring should also be considered for patients taking Fenofibrate Tablets at risk for renal insufficiency such as the elderly and patients with diabetes.
• Cholelithiasis
Fenofibrate, like clofibrate and gemfibrozil, may increase cholesterol excretion into the bile, Leading to Cholelithiasis. If cholelithiasis is suspected, gallbladder studies are indicated.
Fenofibrate Tablets therapy should be discontinued if gallstones are found.
• Coumarin Anticoagulants
Caution should be exercised when coumarin anticoagulants are given in conjunction with Fenofibrate Tablets because of the potentiation of coumarin-type anticoagulant effects in prolonging the Prothrombin Time/International Normalized Ratio (PT/INR). To prevent bleeding complications, frequent monitoring of PT/INR and dose adjustment of the anticoagulant are recommended until PT/INR has stabilized.
• Pancreatitis
Pancreatitis has been reported in patients taking fenofibrate, gemfibrozil, and clofibrate. This Occurrence may represent a failure of efficacy in patients with severe hypertriglyceridemia, a direct drug effect, or a secondary phenomenon mediated through biliary tract stone or sludge formation with obstruction of the common bile duct.
• Hematologic Changes
Mild to moderate hemoglobin, hematocrit, and white blood cell decreases have been observed in patients following initiation of fenofibrate therapy. However, these levels stabilize during long term administration. Thrombocytopenia and agranulocytosis have been reported in individuals treated with fenofibrate. Periodic monitoring of red and white blood cell counts are recommended during the first 12 months of Fenofibrate Tablets administration.
• Hypersensitivity Reactions
Acute Hypersensitivity
Anaphylaxis and angioedema have been reported postmarketing with fenofibrate. In some cases, reactions were life-threatening and required emergency treatment. If a patient develops signs or symptoms of an acute hypersensitivity reaction, advise them to seek immediate medical attention and discontinue fenofibrate.
Delayed Hypersensitivity
Severe cutaneous adverse drug reactions (SCAR), including Stevens-Johnson syndrome, toxic epidermal necrolysis, and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have been reported postmarketing, occurring days to weeks after initiation of fenofibrate. The cases of DRESS were associated with cutaneous reactions (such as rash or exfoliative dermatitis) and a combination of eosinophilia, fever, systemic organ involvement (renal, hepatic, or respiratory). Discontinue fenofibrate and treat patients appropriately if SCAR is suspected
• Venothromboembolic Disease
In the FIELD trial, pulmonary embolus (PE) and deep vein thrombosis (DVT) were observed at higher rates in the fenofibrate- than the placebo-treated group. Of 9,795 patients enrolled in FIELD, there were 4,900 in the placebo group and 4,895 in the fenofibrate group. For DVT, there were 48 events (1%) in the placebo group and 67 (1%) in the fenofibrate group (p = 0.074); and for PE, there were 32 (0.7%) events in the placebo group and 53 (1%) in the fenofibrate group (p = 0.022).
In the Coronary Drug Project, a higher proportion of the clofibrate group experienced definite or Suspected fatal or nonfatal pulmonary embolism or thrombophlebitis than the placebo group (5.2% vs. 3.3% at five years; p < 0.01).
• Paradoxical Decreases in HDL Cholesterol Levels
There have been postmarketing and clinical trial reports of severe decreases in HDL cholesterol levels (as low as 2 mg/dL) occurring in diabetic and non-diabetic patients initiated on fibrate therapy. The decrease in HDL-C is mirrored by a decrease in apolipoprotein A1. This decrease has been reported to occur within 2 weeks to years after initiation of fibrate therapy. The HDL-C levels remain depressed until fibrate therapy has been withdrawn; the response to withdrawal of fibrate therapy is rapid and sustained. The clinical significance of this decrease in HDL-C is unknown. It is recommended that HDL-C levels be checked within the first few months after initiation of fibrate therapy. If a severely depressed HDL-C level is detected, fibrate therapy should be withdrawn, and the HDL-C level monitored until it has returned to baseline, and fibrate therapy should not be re-initiated
Coumarin Anticoagulants
Potentiation of coumarin-type anticoagulant effects has been observed with prolongation of the PT/INR.
Caution should be exercised when coumarin anticoagulants are given in conjunction with Fenofibrate tablets. The dosage of the anticoagulants should be reduced to maintain the PT/INR at the desired level to prevent bleeding complications. Frequent PT/INR determinations are advisable until it has been definitely determined that the PT/INR has stabilized
Immunosuppressant’s
Immunosuppressant’s such as cyclosporine and tacrolimus can produce nephrotoxicity with decreases in creatinine clearance and rises in serum creatinine, and because renal excretion is the primary elimination route of fibrate drugs including Fenofibrate Tablets, there is a risk that an interaction will lead to deterioration of renal function. The benefits and risks of using Fenofibrate Tablets (fenofibrate tablets) with immunosuppressant’s and other potentially nephrotoxic agents should be carefully considered, and the lowest effective dose employed and renal function monitored.
Bile Acid Binding Resins
Since bile acid binding resins may bind other drugs given concurrently, patients should take Fenofibrate Tablets at least 1 hour before or 4 to 6 hours after a bile acid binding resin to avoid impeding its absorption.
Colchicine
Cases of myopathy, including rhabdomyolysis, have been reported with fenofibrates coadministered with colchicine, and caution should be exercised when prescribing fenofibrate with colchicine.
Pregnancy
Risk Summary
Limited available data with fenofibrate use in pregnant women are insufficient to determine a drug associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, no evidence of embryo-fetal toxicity was observed with oral administration of fenofibrate in rats and rabbits during organogenesis at doses less than or equivalent to the maximum recommended clinical dose of 145 mg daily, based on body surface area (mg/m2). Adverse reproductive outcomes occurred at higher doses in the presence of maternal toxicity (see Data). Fenofibrate Tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data
Animal Data
In pregnant rats given oral dietary doses of 14, 127, and 361 mg/kg/day from gestation day 6-15 during the period of organogenesis, no adverse developmental findings were observed at 14 mg/kg/day (less than the clinical exposure at the maximum recommended human dose [MRHD] of 300 mg fenofibrate daily, equivalent to 145 mg Fenofibrate Tablets daily, based on body surface area Comparisons). Increased fetal skeletal malformations were observed at maternally toxic doses (361 mg/kg/day, corresponding to 12 times the clinical exposure at the MRHD) that significantly suppressed maternal body weight gain In pregnant rabbits given oral gavage doses of 15, 150, and 300 mg/kg/day from gestation day 6- 18 during the period of organogenesis and allowed to deliver, no adverse developmental findings were observed at 15 mg/kg/day (a dose that approximates the clinical exposure at the MRHD, based on body surface area comparisons). Aborted litters were observed at maternally toxic doses (≥ 150 mg/kg/day, corresponding to ≥ 10 times the clinical exposure at the MRHD) that suppressed maternal body weight gain.
In pregnant rats given oral dietary doses of 15, 75, and 300 mg/kg/day from gestation day 15 through lactation day 21 (weaning), no adverse developmental effects were observed at 15 mg/kg/day (less than the clinical exposure at the MRHD, based on body surface area comparisons), despite maternal toxicity (decreased weight gain). Post-implantation loss was observed at ≥ 75 mg/kg/day (≥ 2 times the clinical exposure at the MRHD) in the presence of maternal toxicity (decreased weight gain). Decreased pup survival was noted at 300 mg/kg/day (10 times the clinical exposure at the MRHD), which was associated with decreased maternal body weight gain/maternal neglect.
Lactation
Risk Summary
There is no available information on the presence of fenofibrate in human milk, effects of the drug on the breastfed infant, or the effects on milk production. Fenofibrate is present in the milk of rats, and is therefore likely to be present in human milk. Because of the potential for serious adverse reactions in breastfed infants, such as disruption of infant lipid metabolism, women should not breastfeed during treatment with Fenofibrate Tablets and for 5 days after the final dose.
Pediatric Use
Safety and effectiveness have not been established in pediatric patients.
Geriatric Use
Fenofibric acid is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Fenofibric acid exposure is not influenced by age. Since elderly patients have a higher incidence of renal impairment, dose selection for the elderly should be made on the basis of renal function. Elderly patients with normal renal function should require no dose modifications. Consider monitoring renal function in elderly patients taking Fenofibrate Tablets.
Renal Impairment
The use of Fenofibrate Tablets should be avoided in patients who have severe renal impairment Dose reduction is required in patients with mild to moderate renal Impairment. Monitoring renal function in patients with renal impairment is recommended.
Hepatic Impairment
The use of Fenofibrate Tablets has not been evaluated in subjects with hepatic impairment
Fenofibrate Tablets 48mg and 145mg has no or negligible influence on the ability to drive and use machines.
Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates Observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adverse events reported by 2% or more of patients treated with fenofibrate (and greater than placebo) during the double-blind, placebo-controlled trials, regardless of causality, are listed in Table 1 below.
Adverse events led to discontinuation of treatment in 5.0% of patients treated with fenofibrate and in 3.0% treated with placebo. Increases in liver function tests were the most frequent events, causing discontinuation of fenofibrate treatment in 1.6% of patients in double blind trials.

Postmarketing Experience
The following adverse reactions have been identified during post approval use of fenofibrate.
Because these reactions are reported voluntarily from a population of uncertain size, it is not Always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: myalgia, rhabdomyolysis, pancreatitis, acute renal failure, muscle spasm, hepatitis, cirrhosis, anemia, arthralgia, decreases in hemoglobin, decreases in hematocrit, white blood cell decreases, asthenia, severely depressed HDL-cholesterol levels, and interstitial lung disease.
Photosensitivity reactions have occurred days to months after initiation; in some of these cases, Patients reported a prior photosensitivity reaction to ketoprofen.

There is no specific treatment for overdose with Fenofibrate Tablets. General supportive care of the patient is indicated, including monitoring of vital signs and observation of clinical status, should an overdose occur. If indicated, elimination of unabsorbed drug should be achieved by emesis or gastric lavage; usual precautions should be observed to maintain the airway. Because fenofibric acid is highly bound to plasma proteins, hemodialysis should not be considered.
12.1 Mechanism of Action
The active moiety of Fenofibrate Tablets is fenofibric acid. The pharmacological effects of fenofibric acid in both animals and humans have been extensively studied through oral administration of fenofibrate.
The lipid-modifying effects of fenofibric acid seen in clinical practice have been explained in vivo in transgenic mice and in vitro in human hepatocyte cultures by the activation of peroxisome proliferator activated receptor α (PPARα). Through this mechanism, fenofibrate increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase and reducing production of apoprotein C-III (an inhibitor of lipoprotein lipase activity).
The resulting decrease in TG produces an alteration in the size and composition of LDL from small, dense particles (which are thought to be atherogenic due to their susceptibility to oxidation), to large buoyant particles. These larger particles have a greater affinity for cholesterol receptors and are catabolized rapidly. Activation of PPARα also induces an increase in the synthesis of apolipoproteins A-I, A-II and HDL-cholesterol. Fenofibrate also reduces serum uric acid levels in hyperuricemia and normal individuals by Increasing the urinary excretion of uric acid.
5.1 Pharmacodynamic properties
A variety of clinical studies have demonstrated that elevated levels of total-C, LDL-C, and apo B, an LDL membrane complex, are associated with human atherosclerosis. Similarly, decreased levels of HDL-C and its transport complex, apolipoprotein A (apo AI and apo AII) are associated with the development of atherosclerosis. Epidemiologic investigations have established that cardiovascular morbidity and mortality vary directly with the level of total-C, LDL-C, and TG, and inversely with the level of HDL-C. The independent effect of raising HDL-C or lowering triglycerides (TG) on the risk of cardiovascular morbidity and mortality has not been determined. Fenofibric acid, the active metabolite of fenofibrate, produces reductions in total cholesterol, LDL cholesterol, apolipoprotein B, total triglycerides and triglyceride rich lipoprotein (VLDL) in treated patients. In addition, treatment with fenofibrate results in increases in high density lipoprotein (HDL) and apolipoproteins apoAI and apoAII
Plasma concentrations of fenofibric acid after administration of three 48 mg or one 145 mg tablets are equivalent under fed conditions to one 200 mg micronized fenofibrate capsule. Fenofibrate is a pro-drug of the active chemical moiety fenofibric acid. Fenofibrate is converted by ester hydrolysis in the body to fenofibric acid which is the active constituent measurable in the circulation.
Absorption
The absolute bioavailability of fenofibrate cannot be determined as the compound is virtually insoluble in aqueous media suitable for injection. However, fenofibrate is well absorbed from the Gastrointestinal tract. Following oral administration in healthy volunteers, approximately 60% of a single dose of radiolabelled fenofibrate appeared in urine, primarily as fenofibric acid and its glucuronate conjugate, and 25% was excreted in the feces. Peak plasma levels of fenofibric acid occur within 6 to 8 hours after administration.
Exposure to fenofibric acid in plasma, as measured by Cmax and AUC, is not significantly different when a single 145 mg dose of fenofibrate is administered under fasting or non fasting conditions.
Distribution
Upon multiple dosing of fenofibrate, fenofibric acid steady state is achieved within 9 days. Plasma concentrations of fenofibric acid at steady state are approximately double of those following a single dose. Serum protein binding was approximately 99% in normal and hyperlipidaemia subjects.
Metabolism
Following oral administration, fenofibrate is rapidly hydrolyzed by esterases to the active metabolite, fenofibric acid; no unchanged fenofibrate is detected in plasma. Fenofibric acid is primarily conjugated with glucuronic acid and then excreted in urine. A small amount of fenofibric acid is reduced at the carbonyl moiety to a benzhydrol metabolite which is, in turn, conjugated with glucuronic acid and excreted in urine.
In vivo metabolism data indicate that neither fenofibrate nor fenofibric acid undergo oxidative Metabolism (e.g., cytochrome P450) to a significant extent.
Elimination
After absorption, fenofibrate is mainly excreted in the urine in the form of metabolites, primarily fenofibric acid and fenofibric acid glucuronide. After administration of radiolabelled fenofibrate, approximately 60% of the dose appeared in the urine and 25% was excreted in the feces.
Fenofibric acid is eliminated with a half-life of 20 hours, allowing once daily dosing.
Special Populations
Geriatrics
In elderly volunteers 77 to 87 years of age, the oral clearance of fenofibric acid following a single oral dose of fenofibrate was 1.2 L/h, which compares to 1.1 L/h in young adults. This indicates that a similar dosage regimen can be used in elderly with normal renal function, without increasing accumulation of the drug or metabolites.
Pediatrics
The pharmacokinetics of Fenofibrate Tablets has not been studied in pediatric populations Gender No pharmacokinetic difference between males and females has been observed for fenofibrate.
Race
The influence of race on the pharmacokinetics of fenofibrate has not been studied, however fenofibrate is not metabolized by enzymes known for exhibiting inter-ethnic variability.
Renal Impairment
The pharmacokinetics of fenofibric acid was examined in patients with mild, moderate, and severe renal impairment. Patients with severe renal impairment (estimated glomerular filtration rate [eGFR] < 30 mL/min/1.73m2) showed 2.7-fold increase in exposure for fenofibric acid and increased accumulation of fenofibric acid during chronic dosing compared to that of healthy subjects. Patients with mild to moderate renal impairment (eGFR 30-59 mL/min/1.73m2) had similar exposure but an increase in the half-life for fenofibric acid compared to that of healthy subjects. Based on these findings, the use of Fenofibrate Tablets should be avoided in patients who have
Severe renal impairment and dose reduction is required in patients having mild to moderate renal Impairment.
Hepatic Impairment
No pharmacokinetic studies have been conducted in patients with hepatic impairment.
Drug-drug Interactions
In vitro studies using human liver microsomes indicate that fenofibrate and fenofibric acids are not inhibitors of cytochrome (CYP) P450 isoforms CYP3A4, CYP2D6, CYP2E1, or CYP1A2. They are weak inhibitors of CYP2C8, CYP2C19 and CYP2A6, and mild-to-moderate inhibitors of CYP2C9 at therapeutic concentrations.

Carcinogenesis and Mutagenesis and Impairment of Fertility
Two dietary carcinogenicity studies have been conducted in rats with fenofibrate. In the first 24- month study, Wistar rats were dosed with fenofibrate at 10, 45, and 200 mg/kg/day, approximately 0.3, 1, and 6 times the maximum recommended human dose (MRHD) of 300 mg Fenofibrate daily, equivalent to 145 mg Fenofibrate Tablets daily, based on body surface area comparisons.
At a dose of 200 mg/kg/day (at 6 times the MRHD), the incidence of liver carcinomas was significantly increased in both sexes. A statistically significant increase in pancreatic carcinomas was observed in males at 1 and 6 times the MRHD; an increase in pancreatic adenomas and benign testicular interstitial cell tumour’s was observed at 6 times the MRHD in males. In a second 24-month rat carcinogenicity study in a different strain of rats (Sprague-Dawley), doses of 10 and 60 mg/kg/day (0.3 and 2 times the MRHD) produced significant increases in the incidence of pancreatic acinar adenomas in both sexes and increases in testicular interstitial cell tumors in males at 2 times the MRHD.
A 117-week carcinogenicity study was conducted in rats comparing three drugs: fenofibrate 10 and 60 mg/kg/day (0.3 and 2 times the MRHD, based on body surface area comparisons), clofibrate (400 mg/kg/day; 2 times the human dose), and gemfibrozil (250 mg/kg/day; 2 times the human dose, based on mg/m2 surface area). Fenofibrate increased pancreatic acinar adenomas in both sexes. Clofibrate increased hepatocellular carcinoma and pancreatic acinar adenomas in males and hepatic neoplastic nodules in females. Gemfibrozil increased hepatic neoplastic nodules in males and females, while all three drugs increased testicular interstitial cell tumors in males.
In a 21-month study in CF-1 mice, fenofibrate 10, 45, and 200 mg/kg/day (approximately 0.2, 1, and 3 times the MRHD, based on body surface area comparisons) significantly increased the liver carcinomas in both sexes at 3 times the MRHD. In a second 18-month study at 10, 60, and 200 mg/kg/day, fenofibrate significantly increased the liver carcinomas in male mice and liver adenomas in female mice at 3 times the MRHD.
Electron microscopy studies have demonstrated peroxisomal proliferation following fenofibrate administration to the rat. An adequate study to test for peroxisome proliferation in humans has not been done, but changes in peroxisome morphology and numbers have been observed in humans after treatment with other members of the fibrate class when liver biopsies were compared before and after treatment in the same individual.
Fenofibrate has been demonstrated to be devoid of mutagenic potential in the following tests: Ames, mouse lymphoma, chromosomal aberration and unscheduled DNA synthesis in primary rat hepatocytes.
In fertility studies rats were given oral dietary doses of fenofibrate, males received 61 days prior to mating and females 15 days prior to mating through weaning which resulted in no adverse effect on fertility at doses up to 300 mg/kg/day (10 times the MRHD, based on body surface area Comparisons).
