Trirole®
Fenofibrate
100 & 200 mg capsule
Hypercholesterolemia or mixed dyslipidemia, Hypertriglyceridemia
Mechanism of Action:
Fenofibric acid, an agonist for the nuclear transcription factor peroxisome proliferator-activated receptor-alpha (PPAR-alpha), downregulates apoprotein C-III (an inhibitor of lipoprotein lipase) and upregulates the synthesis of apolipoprotein A-I, fatty acid transport protein, and lipoprotein lipase resulting in an increase in VLDL catabolism, fatty acid oxidation, and elimination of triglyceride-rich particles; as a result of a decrease in VLDL levels, total plasma triglycerides are reduced by 30% to 60%; modest increase in HDL occurs in some hypertriglyceridemic patients.
Method of Administration:
100-200 mg once daily
Notes
Contraindications:
Hypersensitivity to fenofibrate or fenofibric acid or any component of the formulation; active liver disease, including primary biliary cirrhosis and unexplained, persistent liver function abnormality; severe renal impairment or end-stage renal disease, including those receiving dialysis; preexisting gallbladder disease; breastfeeding
Interactions:
Bile Acid Sequestrants: May decrease the absorption of Fibric Acid Derivatives. Management: Separate doses by at least 2 hours to minimize this interaction; fenofibric acid labeling recommends administration one hour prior to or 4-6 hours after a bile acid sequestrant. Risk D: Consider therapy modification
HMG-CoA Reductase Inhibitors (Statins): Fenofibrate and Derivatives may enhance the adverse/toxic effect of HMG-CoA Reductase Inhibitors (Statins). Risk C: Monitor therapy
Sulfonylureas: Fibric Acid Derivatives may enhance the hypoglycemic effect of Sulfonylureas. Risk C: Monitor therapy
Pregnancy and Lactation:
Triglyceride and lipid concentrations increase during pregnancy as required for normal fetal development. When increases are greater than expected, supervised dietary intervention should be initiated. In women who develop very severe hypertriglyceridemia and are at risk for pancreatitis, use of fenofibrate beginning in the second trimester is one intervention that may be considered.
It is not known if fenofibrate is present in breast milk. When treatment for very severe hypertriglyceridemia in breastfeeding women at risk for pancreatitis is needed, therapy with fenofibrate may be considered
Warning and Precaution:
- Cholelithiasis: May cause cholelithiasis; discontinue if gallstones are found upon gallbladder studies.
- HDL cholesterol: A paradoxical, severe, and reversible decrease in HDL-C (as low as 2 mg/dL) with a
simultaneous decrease in apolipoprotein A1 has been reported within 2 weeks to years after initiation
of fibrate therapy; clinical significance unknown. Monitor HDL-C within a few months of initiation of
therapy and discontinue if HDL-C becomes severely depressed; do not restart therapy.
- Hematologic effects: May cause mild-to-moderate decreases in hemoglobin, hematocrit and WBC
upon initiation of therapy which usually stabilizes with long-term therapy. Agranulocytosis and
thrombocytopenia has been reported. Periodic monitoring of blood counts is recommended during
the first year of therapy.
- Hepatic effects: Hepatic transaminases can become significantly elevated (dose related); serious
drug-induced liver injury has been reported after weeks to several months of therapy (some cases
have resulted in death or required liver transplant); may be characterized as hepatocellular, chronic
active, and cholestatic hepatitis, and cirrhosis has occurred in association with chronic active hepatitis.
- Hypersensitivity reactions: Acute hypersensitivity reactions, including anaphylaxis and angioedema,
have been reported. Additionally, delayed hypersensitivity reactions, including severe cutaneous
adverse reactions such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and
drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported, occurring days
two weeks following fenofibrate initiation. Discontinue immediately for severe acute or delayed
hypersensitivity reactions.
- Myopathy/Rhabdomyolysis: Has been associated with rare myositis, myopathy, or rhabdomyolysis;
monitor patients closely. Risk increased in the elderly, those receiving concomitant HMG-CoA
reductase inhibitors or colchicine, and patients with diabetes mellitus, renal insufficiency, or
hypothyroidism. Instruct patients to report unexplained muscle pain, tenderness, weakness, especially
if accompanied with malaise or fever; or brown urine. Discontinue therapy in patients who develop
markedly elevated CPK concentrations or if myopathy/myositis is suspected or diagnosed.
- Pancreatitis: Pancreatitis has been reported with fenofibrate use; may be secondary to a failure of
efficacy in patients with severe hypertriglyceridemia, medication side effect, or due to biliary tract
stone or sludge formation from bile duct obstruction.
- Photosensitivity: Photosensitivity reactions have been reported, sometimes days to months after
therapy was initiated; some patients reported previous photosensitivity to ketoprofen.
- Renal effects: Increases in serum creatinine (>2 mg/dL) have been observed with use; clinical
significance unknown. These elevations tend to return to baseline following discontinuation of
fenofibrate. Fenofibrate has been shown to increase creatinine production (unknown mechanism)
resulting in an equal increase of creatinuria thereby demonstrating that the increase does not reflect a
reduction in creatinine clearance. Monitor renal function in patients with renal
impairment; consider monitoring renal function in patients with increased risk for developing renal
impairment (eg, elderly and patients with diabetes).
Adverse Reactions:
Hepatic: Increased serum alanine aminotransferase (≥3 x ULN: ≤13%), increased serum aspartate aminotransferase (≥3 x ULN: ≤13%), Skin rash, urticaria, Abnormal hepatic function tests,
Storage:
Store below 30 and protect from light and moisture.
