Fenofibrate is a fibric acid derivative, a prodrug comprising fenofibric acid linked to an isopropyl ester. Fenofibrate 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. Fenofibrate also reduces serum uric acid levels in hyperuricemic and normal individuals by increasing the urinary excretion of uric acid.
Fenofibrate is a fibrate that activates peroxisome proliferator activated receptor alpha (PPARα) to alter lipid metabolism and treat primary hypercholesterolemia, mixed dyslipidemia, and severe hypertriglyceridemia. Fenofibrate requires once daily dosing and has a half life of 19-27 hours so its duration of action is long. Fenofibrate 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
Fenofibrate 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
Evothyl 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 Evothyl works
Fenofibrate 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
Evothyl 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. Fenofibrate 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.
Volume of Distribution
The volume of distribution of fenofibrate is 0.89L/kg, and can be as high as 60L.
Elimination Route
A single 300mg oral dose of fenofibrate reaches a Cmax of 6-9.5mg/L with a Tmax of 4-6h in healthy, fasting volunteers.
Half Life
Fenofibric acid, the active metabolite of fenofibrate, has a half life of 23 hours. Fenofibrate has a half life of 19-27 hours in healthy subjects and up to 143 hours in patients with renal failure.
Clearance
The oral clearance of fenofibrate is 1.1L/h in young adults and 1.2L/h in the elderly.
Elimination Route
5-25% of a dose of fenofibrate is eliminated in the feces, while 60-88% is eliminated in the urine. 70-75% of the dose recovered in the urine is in the form of fenofibryl glucuronide and 16% as fenofibric acid.
Pregnancy & Breastfeeding use
Pregnancy Category C. Fenofibrate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nursing mothers: Fenofibrate should not be used in nursing mothers. Because of the potential for tumorigenicity seen in animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug.
Contraindication
Fenofibrate is contraindicated in patients with-
- Hypersensitivity to fenofibrate or any component of this medication.
- Known photoallergy or phototoxic reaction during treatment with fibrates or ketoprofen.
- Severe liver dysfunction, gallbladder disease, biliary cirrhosis, severe renal disorders.
- Chronic or acute pancreatitis with the exception of acute pancreatitis due to severe hypertriglyceridemia.
- Pregnancy and lactation.
Special Warning
Geriatrics: This indicates that a similar dosage regimen can be used in the elderly, without increasing accumulation of the drug or metabolites.
Pediatrics: No data are available. Fenofibrate is not indicated for use in the pediatric population.
Gender: No pharmacokinetic difference between male and female has been observed for fenofibrate.
Renal insufficiency: The dosage of fenofibrate should be minimized in patients who have severe renal impairment, while no modification of dosage is required in patients having moderate renal impairment.
Hepatic insufficiency: No pharmacokinetic study has been conducted in patients having hepatic insufficiency.
Storage Condition
Store at cool & dry place. Protect from light and moisture.
