Pharmacology

πŸ”¬

Mechanism of Action

Fenofibrate is a prodrug that is rapidly hydrolyzed to its active metabolite, fenofibric acid. Fenofibric acid activates peroxisome proliferator-activated receptor alpha (PPARΞ±), a nuclear receptor that regulates lipid metabolism. Through activation of PPARΞ±, fenofibric acid increases lipolysis and elimination of triglyceride-rich particles from plasma by activating lipoprotein lipase and reducing production of apolipoprotein C-III (an inhibitor of lipoprotein lipase activity). It also increases the synthesis of apolipoproteins A-I and A-II, leading to increased HDL-C levels. These actions result in reductions in total cholesterol, LDL-C, triglycerides, and apolipoprotein B, and increases in HDL-C.
πŸ“Š

Pharmacokinetics

Absorption:

Bioavailability: Variable, enhanced by food. Fenofibric acid bioavailability is approximately 81% when taken with food.
Tmax: Fenofibric acid: 6 to 8 hours (for 40mg tablets, which are often micronized or nanocrystallized formulations, Tmax can be shorter, e.g., 2-4 hours for some formulations).
FoodEffect: Absorption is increased by approximately 35% when taken with food. Therefore, it should be taken with meals.

Distribution:

Vd: Not readily available for fenofibric acid, but extensive tissue distribution is expected.
ProteinBinding: Fenofibric acid: >99% (primarily to albumin).
CnssPenetration: Limited

Elimination:

HalfLife: Fenofibric acid: Approximately 20 hours.
Clearance: Primarily renal.
ExcretionRoute: Mainly urine (approximately 60% as fenofibric acid and its glucuronide conjugate), some in feces (approximately 25%).
Unchanged: Less than 2% of fenofibric acid is excreted unchanged in urine.
⏱️

Pharmacodynamics

OnsetOfAction: Lipid-lowering effects typically begin within days to weeks.
PeakEffect: Maximal lipid-lowering effects are usually observed within 4 to 8 weeks of therapy initiation.
DurationOfAction: Effects persist as long as therapy is continued.

Overdose Information

Overdose Symptoms:

  • No specific symptoms of overdose have been reported, but potential effects could include increased severity of known adverse reactions such as muscle pain, liver enzyme elevations, or gastrointestinal upset.

What to Do:

In case of suspected overdose, contact a poison control center or emergency room immediately. Treatment is generally supportive and symptomatic. Fenofibric acid is not dialyzable.

Drug Interactions

πŸ”΄

Major Interactions

  • Statins (HMG-CoA reductase inhibitors): Increased risk of myopathy/rhabdomyolysis.
  • Warfarin: Potentiation of anticoagulant effect, increased risk of bleeding.
  • Cyclosporine: Increased risk of renal dysfunction.
🟑

Moderate Interactions

  • Bile acid sequestrants (e.g., cholestyramine, colestipol): May reduce fenofibrate absorption. Administer fenofibrate at least 1 hour before or 4-6 hours after bile acid sequestrants.
  • Colchicine: Possible increased risk of myopathy/rhabdomyolysis (though less established than with statins).
🟒

Minor Interactions

  • Oral contraceptives: May slightly alter lipid profiles, but generally not clinically significant.

Monitoring

πŸ”¬

Baseline Monitoring

Lipid Panel (Total Cholesterol, LDL-C, HDL-C, Triglycerides)

Rationale: To establish baseline lipid levels and confirm indication for therapy.

Timing: Prior to initiation of therapy.

Liver Function Tests (ALT, AST, ALP, Bilirubin)

Rationale: To assess baseline hepatic function and identify pre-existing liver disease, as fenofibrate can cause transaminase elevations.

Timing: Prior to initiation of therapy.

Renal Function (Serum Creatinine, eGFR)

Rationale: To assess baseline renal function, as fenofibrate is primarily renally eliminated and dose adjustments are required in renal impairment.

Timing: Prior to initiation of therapy.

Complete Blood Count (CBC)

Rationale: To assess for baseline hematologic abnormalities, though rare, blood dyscrasias have been reported.

Timing: Prior to initiation of therapy.

πŸ“Š

Routine Monitoring

Lipid Panel (Total Cholesterol, LDL-C, HDL-C, Triglycerides)

Frequency: Every 4-8 weeks initially, then every 6-12 months once stable.

Target: Individualized based on patient risk factors and guidelines (e.g., Triglycerides <150 mg/dL, LDL-C <100 mg/dL or lower depending on risk).

Action Threshold: Failure to achieve target lipid levels, or significant worsening of lipid profile.

Liver Function Tests (ALT, AST)

Frequency: Every 3 months for the first year, then periodically (e.g., every 6-12 months) or as clinically indicated.

Target: Within normal limits (typically <3x Upper Limit of Normal).

Action Threshold: Persistent ALT/AST elevations >3x ULN; consider discontinuation if >5x ULN.

Renal Function (Serum Creatinine, eGFR)

Frequency: Periodically (e.g., every 6-12 months) or as clinically indicated, especially in patients with pre-existing renal impairment or risk factors.

Target: Stable eGFR, within acceptable limits for patient.

Action Threshold: Significant decrease in eGFR (e.g., >20% from baseline) or progression of renal impairment; consider dose adjustment or discontinuation.

Creatine Kinase (CK)

Frequency: As clinically indicated (e.g., if muscle pain, tenderness, or weakness occurs).

Target: Within normal limits.

Action Threshold: Significant elevation of CK (e.g., >5x ULN) or symptoms of myopathy/rhabdomyolysis; discontinue fenofibrate.

πŸ‘οΈ

Symptom Monitoring

  • Unexplained muscle pain, tenderness, or weakness (especially if accompanied by malaise or fever)
  • Dark urine
  • Yellowing of skin or eyes (jaundice)
  • Unusual fatigue or weakness
  • Abdominal pain
  • Nausea or vomiting
  • Signs of bleeding (e.g., unusual bruising, prolonged bleeding from cuts, blood in urine or stool) if on warfarin

Special Patient Groups

🀰

Pregnancy

Category C. There are no adequate and well-controlled studies in pregnant women. Fenofibrate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Lipid levels naturally increase during pregnancy, and the need for lipid-lowering therapy is generally not established.

Trimester-Specific Risks:

First Trimester: Potential for fetal harm based on animal studies (skeletal malformations, reduced fetal weight at high doses).
Second Trimester: Limited human data, animal studies suggest potential for adverse effects at high doses.
Third Trimester: Limited human data, animal studies suggest potential for adverse effects at high doses.
🀱

Lactation

It is not known whether fenofibric acid is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Generally not recommended.

Infant Risk: Risk level L3 (Moderate concern). Potential for unknown adverse effects on the infant.
πŸ‘Ά

Pediatric Use

Safety and efficacy have not been established in pediatric patients. Use is generally not recommended unless the potential benefit clearly outweighs the potential risks, and only under specialist supervision.

πŸ‘΄

Geriatric Use

No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Renal function should be monitored.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Fenofibrate should always be taken with food to optimize absorption and efficacy.
  • Regular monitoring of liver function tests (LFTs) and renal function is crucial, especially during the first year of treatment.
  • Patients should be advised to report any unexplained muscle pain, tenderness, or weakness immediately, as this could indicate myopathy or rhabdomyolysis.
  • Fenofibrate is particularly effective at lowering very high triglyceride levels and can also improve HDL-C and LDL-C.
  • When co-administering with bile acid sequestrants, separate doses by at least 1 hour before or 4-6 hours after the sequestrant to avoid reduced absorption of fenofibrate.
  • Patients on warfarin require close monitoring of INR when initiating or discontinuing fenofibrate, or changing its dose, due to potential for increased anticoagulant effect.
πŸ”„

Alternative Therapies

  • Other fibrates (e.g., Gemfibrozil)
  • Statins (e.g., Atorvastatin, Rosuvastatin, Simvastatin) - primary agents for LDL-C lowering, some also lower triglycerides.
  • Omega-3 fatty acid ethyl esters (e.g., Icosapent ethyl, Omega-3-acid ethyl esters) - for severe hypertriglyceridemia.
  • PCSK9 inhibitors (e.g., Alirocumab, Evolocumab) - for severe hypercholesterolemia.
  • Niacin (Nicotinic acid) - for dyslipidemia (less commonly used due to side effects).
  • Bempedoic acid (Nexletol) - for hypercholesterolemia.
  • Ezetimibe (Zetia) - for hypercholesterolemia.
