Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Fenofibrate is a peroxisome proliferator-activated receptor alpha (PPARα) agonist. It increases lipolysis and elimination of triglyceride-rich particles from plasma, reduces hepatic production of VLDL, and increases HDL cholesterol.
TRILIPIX (fenofibric acid) is a peroxisome proliferator-activated receptor alpha (PPARα) agonist. It increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase, and reduces production of apoprotein C-III.

Hepatic metabolism via glucuronidation; minor CYP450 involvement (CYP3A4).
Fenofibric acid is primarily metabolized via glucuronidation. It is not metabolized by cytochrome P450 (CYP) enzymes.
Fenoglide (fenofibrate) is primarily excreted in urine as fenofibric acid and its glucuronide conjugate, accounting for approximately 60-70% of the dose. About 20-25% is eliminated in feces via biliary excretion. Renal excretion is the major route.

Fenofibric acid is highly bound to plasma albumin (>99%).
The apparent volume of distribution (Vd) of fenofibric acid is approximately 0.9 L/kg. This suggests distribution into total body water, with some tissue binding.

Take with food to enhance absorption. Avoid high-fat meals immediately before or after dose. Grapefruit juice may increase fenofibrate exposure (moderate interaction, monitor). Statin co-administration: avoid large amounts of grapefruit juice.
Avoid high-fat meals during administration as they can alter fenofibric acid absorption. Avoid grapefruit juice as it may increase drug exposure. Alcohol consumption should be limited (no more than 1 drink per day for women, 2 for men) due to potential hepatotoxicity and worsening of hypertriglyceridemia.
First trimester: No adequate studies; animal data show no major malformations at clinically relevant doses. Second and third trimesters: Associated with adverse maternal and fetal outcomes (e.g., preterm birth, low birth weight) due to β-receptor agonist effects. Avoid use during pregnancy.
Pregnancy category C. First trimester: No adequate studies in humans; animal studies show fetal toxicity at high doses. Second and third trimesters: Use only if benefit outweighs risk; may cause fetal harm due to maternal hypertriglyceridemia or drug effects.
Excreted in breast milk; M/P ratio unknown. Potential for neonatal β-receptor stimulation. Caution advised; manufacturer recommends discontinuing breastfeeding or drug.
Not recommended. M/P ratio unknown; fenofibric acid is excreted in rat milk; potential for serious adverse reactions in nursing infants.
No established dose adjustments for pregnancy; use only if potential benefit outweighs risk. Consideration of lower doses due to altered pharmacokinetics (increased clearance, decreased plasma concentration).
No established dosing adjustments; pharmacokinetics in pregnancy unknown. Use lowest effective dose if necessary; avoid in third trimester unless essential.
Fenofibrate is a fibric acid derivative used primarily for hypertriglyceridemia and mixed dyslipidemia. It activates PPAR-alpha, increasing lipoprotein lipase and reducing apolipoprotein C-III. Monitor renal function; dose adjustment required for Cr Cl 30-60 m L/min. Contraindicated in severe renal impairment (Cr Cl <30) and active liver disease. Can increase serum creatinine, but this is often reversible. Co-administration with statins increases risk of myopathy, especially in elderly or renal impairment. May increase homocysteine levels; monitor if at risk for thrombosis.
TRILIPIX (fenofibric acid) is a fibric acid derivative used as an adjunct to diet for severe hypertriglyceridemia. Monitor renal function prior to initiation and periodically; dose reduction required for e GFR 30-59 m L/min/1.73m². Contraindicated in severe renal impairment (e GR <30) and active liver disease. May increase serum creatinine; typically reversible. Co-administration with statins increases risk of myopathy/rhabdomyolysis; avoid in patients with predisposing factors. Not recommended for primary prevention of coronary heart disease.

FENOGLIDE is a Antilipemic that works by Fenofibrate is a peroxisome proliferator-activated receptor alpha (PPARα) agonist. It increases lipolysis and elimination of triglyceride-rich particles from plasma, reduces hepatic production of VLDL, and increases HDL cholesterol.. TRILIPIX is a Fibrate Antilipemic that works by TRILIPIX (fenofibric acid) is a peroxisome proliferator-activated receptor alpha (PPARα) agonist. It increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase, and reduces production of apoprotein C-III.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between FENOGLIDE and TRILIPIX depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of FENOGLIDE is: 160 mg orally once daily, taken with or without food.. The standard adult dose of TRILIPIX is: 135 mg orally once daily, not to exceed 135 mg/day.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between FENOGLIDE and TRILIPIX in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. FENOGLIDE is classified as Category C. First trimester: No adequate studies; animal data show no major malformations at clinically relevant doses. Second and third trimesters: Associated with adverse maternal and fetal . TRILIPIX is classified as Category C. Pregnancy category C. First trimester: No adequate studies in humans; animal studies show fetal toxicity at high doses. Second and third trimesters: Use only if benefit outweighs r. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
