Study Notes
Fluconazole Overview
- Therapeutic class: Antifungal.
- Pharmacologic class: Inhibitor of fungal cell membrane synthesis; belongs to the azole group.
Mechanism of Action
- Interferes with ergosterol synthesis in fungal cell membranes.
- Rapidly and completely absorbed when administered orally.
Efficacy and Uses
- Highly effective against Candida albicans infections.
- Capable of penetrating most body membranes, including the CNS, bone, eye, urinary tract, and respiratory tract.
- Approved for prophylaxis of fungal infections in patients with AIDS, those undergoing bone marrow transplants, and those receiving antineoplastic treatments.
- Limited effectiveness against non-albicans Candida species.
Administration Protocol
- Do not mix intravenous fluconazole with other medications.
- Classified as a pregnancy category C drug.
Adverse Effects
- Generally well tolerated; possible side effects include nausea, vomiting, and diarrhea, especially at high doses.
- Hepatotoxicity is rare, but caution is advised in patients with hepatic impairment.
- Risk of Stevens-Johnson syndrome particularly in immunosuppressed patients.
Contraindications
- Contraindicated in individuals with hypersensitivity to fluconazole.
- Use with caution in patients with chronic kidney disease (CKD) due to renal excretion of the drug.
Drug Interactions
- Strong inhibitor of hepatic CYP450 enzymes, increasing potential for drug interactions.
- Co-administration with warfarin may heighten bleeding risk.
- May cause hypoglycemia when used with certain oral hypoglycemics like glyburide.
- Concurrent use with rifampin or cimetidine may reduce fluconazole levels.
- Prolonged effects of fentanyl, alfentanil, or methadone may occur with simultaneous fluconazole administration.
Lab Considerations
- Monitor liver function tests; may show increased AST, ALT, and alkaline phosphatase values.
- No known interactions with herbal or food substances.
- Dialysis can lower serum levels in the case of overdose; no specific antidote exists for fluconazole overdose.
