Fibral
Fibral Uses, Dosage, Side Effects, Food Interaction and all others data.
Fibral is a fibric acid derivative, a prodrug comprising fenofibric acid linked to an isopropyl ester. Fibral is rapidly hydrolyzed after oral ingestion to its pharmacologically active form, fenofibric acid. The 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)
It lowers lipid levels by activating peroxisome proliferator-activated receptor alpha (PPARα). PPARα activates lipoprotein lipase and reduces apoprotein CIII (an inhibitor of lipoprotein lipase activity), which increases lipolysis and elimination of triglyceride-rich particles from plasma. The resulting fall in triglycerides 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
PPARα also increases apoproteins AI and AII, reduces VLDL- and LDL-containing apoprotein B, and increases HDL-containing apoprotein AI and AII. Fibral also reduces serum uric acid levels in hyperuricemic and normal individuals by increasing the urinary excretion of uric acid.
Fibral is a fibrate that activates peroxisome proliferator activated receptor alpha (PPARα) to alter lipid metabolism and treat primary hypercholesterolemia, mixed dyslipidemia, and severe hypertriglyceridemia. Fibral requires once daily dosing and has a half life of 19-27 hours so its duration of action is long. Fibral capsules are given at a dose of 50-150mg daily so the therapeutic index is wide. Patients should be counselled about the risk of rhabdomyolysis, myopathy, and cholelithiasis when taking fibrates.

Uses
Fibral is used for an adjunct to diet and other non pharmacological treatment (e.g. exercise, weight reduction) for the following:
- Treatment of severe hypertriglyceridemia with or without low HDL cholesterol.
- Mixed hyperlipidemia when a statin is contraused or not tolerated.
- Mixed hyperlipidemia in patients at high cardiovascular risk in addition to a statin when triglycerides and HDL cholesterol are not adequately controlled
Fibral is also used to associated treatment for these conditions: Mixed Dyslipidemias, Primary Hypercholesterolemia, Severe Hypertriglyceridemia, Severe Fredrickson Type IV Hypertriglyceridemia, Severe Fredrickson Type V Hypertriglyceridemia
How Fibral works
Fibral activates peroxisome proliferator activated receptor alpha (PPARα), increasing lipolysis, activating lipoprotein lipase, and reducing apoprotein C-III. PPARα is a nuclear receptor and its activation alters lipid, glucose, and amino acid homeostasis. Activation of PPARα activates transcription of gene transcription and translation that generates peroxisomes filled with hydrogen peroxide, reactive oxygen species, and hydroxyl radicals that also participate in lipolysis. This mechanism of increased lipid metabolism is also associated with increased oxidative stress on the liver. In rare cases this stress can lead to cirrhosis and chronic active hepatitis.
Dosage
Fibral dosage
The dose is one 200 mg capsule per day. Dosage should be individualized according to patient response, and should be increased sequentially if necessary following repeat serum triglyceride estimations at 4 to 8 week intervals. Patients should be placed on an appropriate triglyceride-lowering diet before receiving fenofibrate, and should continue this diet during treatment with fenofibrate. Fibral should be given with meals, thereby optimizing the bioavailability of the medication.
Side Effects
Digestive: hepatitis, cholelithiasis, cholecystitis, hepatomegaly
Musculoskeletal: myalgia, myasthenia, rhabdomyolysis
Skin and appendages: photosensitivity, eczema
Cardiovascular: peripheral edema, angina, palpitations, tachycardia, and migraine
Toxicity
The oral LD50 in rats is >2g/kg and in mice is 1600mg/kg. The oral TDLO in rats is 9mg/kg.
Treat patients with supportive care including monitoring of vital signs and observing clinical status. Recent overdose may be treated with inducing vomiting or gastric lavage. Due to fenofibrate's extensive protein binding, hemodialysis is not expected to be useful.
Precaution
Increased risk of cholelithiasis, pancreatitis, skeletal muscle effects. Patient at risk of rhabdomyolysis. Renal impairment. Pregnancy.
Interaction
Oral Anticoagulants: Caution should be exercised when anticoagulants are given in conjunction with fenofibrate. The dosage of the anticoagulants should be reduced to maintain the prothrombin time at the desired level to prevent bleeding complications.
Resins: Since bile acid sequestrants may bind other drugs given concurrently, patients should take fenofibrate at least 1 hour before or 4-6 hours after a bile acid binding resin to avoid impending its absorption.
Cyclosporine: Because cyclosporine 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, there is a risk that an interaction will lead to deterioration.
Food Interaction
- Take with food. Bioavailability is increased 2- to 3-fold when taken with food.
Fibral Cholesterol interaction
[Major] There have been reports of severe decreases in HDL cholesterol (HDL-C) levels (as low as 2 mg The decrease has been reported to occur within 2 weeks to years after initiation of therapy. It is recommended that HDL-C levels be checked within the first few months after initiation therapy and if a severely depressed HDL-C level is detected, therapy with these agents should be withdrawn. Monitor HDL-C level until it has returned to baseline, and therapy with these agents should not be re-initiated in these patients.

FAQ
What is Fibral used for?
