LIPIDIL vs TRIGLIDE
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
LIPIDIL (fenofibrate) is a fibric acid derivative that activates peroxisome proliferator-activated receptor-alpha (PPAR-alpha), leading to increased lipolysis and clearance of triglyceride-rich particles, and increased synthesis of apolipoproteins A-I and A-II.
TRIGLIDE (fenofibrate) is a peroxisome proliferator-activated receptor alpha (PPARα) activator. It increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase and reducing production of apolipoprotein C-III.
Primary hypercholesterolemia or mixed dyslipidemia (as adjunct to diet),Severe hypertriglyceridemia,Prevention of pancreatitis in patients with hypertriglyceridemia
Adjunctive therapy to diet for severe hypertriglyceridemia (Fredrickson types IV and V),Primary hypercholesterolemia or mixed dyslipidemia (Fredrickson types IIa and IIb)
130 mg orally once daily.
Initial dose: 60 mg (1 tablet) twice daily, gradually increased over 3-7 days to maintenance dose of 120 mg twice daily.
Terminal elimination half-life of fenofibric acid is approximately 20 hours (range 15-25 hours). This supports once-daily dosing; steady-state is achieved after ~5 days.
22-35 hours; prolonged in renal impairment (up to 50 hours).
Fenofibrate is metabolized primarily by glucuronidation; fenofibric acid is further metabolized via reduction to benzhydrol metabolite. Minor involvement of CYP450 enzymes, predominantly CYP3A4.
Fenofibrate is a prodrug that is rapidly hydrolyzed by esterases to the active metabolite fenofibric acid. Fenofibric acid is conjugated with glucuronic acid and excreted in urine. Major CYP450 involvement is minimal; however, fenofibric acid is a substrate of CYP3A4 and to some extent CYP2C8.
Primarily renal excretion of glucuronide conjugates; approximately 70% of a single oral dose is recovered in urine (mostly as fenofibric acid glucuronide), and about 6% is excreted in feces.
Primarily renal (70% as unchanged drug), 20% fecal, <10% biliary.
Fenofibric acid is highly bound to plasma proteins, primarily albumin, with >99% binding.
>99% to albumin.
Apparent volume of distribution (Vd/F) is approximately 0.9 L/kg, indicating distribution into total body water.
0.11-0.16 L/kg; indicates limited extravascular distribution.
Absolute bioavailability of fenofibrate (prodrug) is not determined; fenofibrate is rapidly converted to fenofibric acid with a relative bioavailability of approximately 81-96% compared to the micronized formulation when taken with food. Absorption is enhanced when taken with meals.
60-70% (oral).
GFR 30-89 m L/min: 130 mg once daily; GFR <30 m L/min: contraindicated.
No specific dose adjustment for GFR >10 m L/min; avoid use in patients with GFR <10 m L/min or on dialysis.
Child-Pugh class A: 130 mg once daily; Child-Pugh class B or C: contraindicated.
Contraindicated in Child-Pugh class B and C; use with caution in Child-Pugh class A with dose reduction (e.g., 60 mg twice daily) and monitor closely.
Not recommended for use in pediatric patients.
Not approved for pediatric patients; safety and efficacy not established.
No dose adjustment required, but monitor renal function due to age-related decline.
Use lowest effective dose; monitor for cardiac and electrolyte disturbances; start at 60 mg twice daily and titrate slowly.
There is no FDA black box warning for LIPIDIL.
None
Hepatotoxicity: elevated liver enzymes reported; monitor liver function,Myopathy/rhabdomyolysis: increased risk when combined with statins or in renal impairment,Renal impairment: dose adjustment required; avoid in severe renal impairment,Cholelithiasis: increased bile cholesterol saturation may lead to gallstones, Pancreatitis: despite triglyceride reduction, pancreatitis can occur
Hepatotoxicity: elevations in serum transaminases, rare reports of hepatitis and cirrhosis; monitor hepatic function,Cholelithiasis: increased cholesterol excretion into bile, risk of gallstone formation,Rhabdomyolysis: increased risk in patients with renal impairment, hypothyroidism, or those taking statins or other fibrates,Pancreatitis: observed in patients with severe hypertriglyceridemia,Renal impairment: contraindicated in severe renal disease; dose adjustment needed in mild-to-moderate impairment
Severe renal impairment (e GFR < 30 m L/min),Active liver disease including primary biliary cirrhosis,Pre-existing gallbladder disease,Hypersensitivity to fenofibrate or any component,Nursing mothers (due to potential for tumorigenicity in animal studies)
Severe renal impairment (e GFR < 30 m L/min/1.73 m²),Active liver disease including primary biliary cirrhosis and unexplained persistent liver function abnormalities,Known gallbladder disease,Hypersensitivity to fenofibrate or any component of the formulation,Nursing mothers (due to potential for tumorigenicity in animal studies)
Take with food to enhance absorption. Avoid high-fat meals that may exacerbate hypertriglyceridemia. Grapefruit juice has minimal interaction but caution is advised with statin combinations. Alcohol should be limited or avoided due to potential for elevated triglycerides and hepatotoxicity.
Take with food to enhance bioavailability. Avoid high-fat meals that may exacerbate hypertriglyceridemia. Limit alcohol intake as it can increase triglyceride levels and hepatotoxicity risk. Grapefruit juice has no significant interaction with fenofibrate.
Lipidil (fenofibrate) is contraindicated in pregnancy. Animal studies show fetal toxicity at high doses. Human data are insufficient, but risk cannot be excluded. First trimester: possible embryotoxicity; second and third trimesters: potential for fetal harm due to interference with lipid metabolism.
TRIGLIDE (fenofibrate) is contraindicated in pregnancy due to potential fetal harm. First trimester: no adequate human data; animal studies show embryotoxicity and delayed ossification at doses below human exposure. Second and third trimesters: risk of fetal skeletal abnormalities and growth retardation; use only if maternal benefit outweighs risk.
Contraindicated during breastfeeding. Fenofibrate is excreted in breast milk in animal studies; M/P ratio unknown in humans. Potential for serious adverse effects in breastfed infants, including interference with fatty acid metabolism.
Fenofibrate is excreted in rat milk; no human data. M/P ratio unknown. Breastfeeding is contraindicated due to potential lipid metabolism disruption in infant and lack of safety data.
Lipidil is contraindicated in pregnancy; no dose adjustment recommended. Therapy should be discontinued upon conception or if pregnancy is planned. There are no established dose adjustments for pregnant women due to lack of safety data.
No dose adjustment guidelines due to contraindication. Pharmacokinetics in pregnancy not studied; no recommended dose changes.
Lipidil (fenofibrate) is a PPARα agonist used primarily for severe hypertriglyceridemia and mixed dyslipidemia. Monitor renal function at baseline and periodically; reduce dose in CKD (e GFR <60 m L/min). Avoid in severe hepatic impairment or gallbladder disease. Combines with statins but increases risk of myopathy; monitor for muscle symptoms. May raise serum creatinine and homocysteine levels. Tablet should be swallowed whole; do not crush or chew.
TRIGLIDE (fenofibrate) is a fibric acid derivative used as adjunctive therapy to diet for severe hypertriglyceridemia (≥500 mg/d L) to reduce risk of pancreatitis. Monitor renal function before initiation; dose adjustment required if e GFR 30-59 m L/min (starting dose: 48 mg/day). Avoid use if e GFR <30 m L/min or active liver disease. Coadministration with statins increases risk of myopathy/rhabdomyolysis; discontinue if unexplained muscle pain or weakness occurs.
