Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clotrimazole inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Ketoconazole, an imidazole antifungal agent, inhibits fungal cytochrome P450 14α-demethylase (CYP51), preventing the conversion of lanosterol to ergosterol, an essential component of fungal cell membranes. This disrupts membrane integrity and function.
Clotrimazole 1% cream or solution applied topically to affected area twice daily for 2-4 weeks. For vaginal tablets: 100 mg intravaginally once daily for 7 days or 500 mg single dose. For troches: 10 mg troche dissolved slowly in mouth five times daily for 14 days.
Apply to wet hair, lather, and leave on for 3-5 minutes before rinsing. Use twice weekly for 4 weeks, then as needed to control dandruff.

Terminal elimination half-life is approximately 20-50 hours. Dose adjustments not required in renal impairment, but caution in hepatic impairment.
Terminal elimination half-life is biphasic: initial 2 hours, terminal 8 hours (range 6-10 hours). After topical application, systemic absorption is minimal, resulting in an effective half-life of 72-96 hours in skin.
Approximately 70% of absorbed dose is excreted in feces as unchanged drug and metabolites; about 20% is excreted renally as metabolites with less than 1% unchanged. Biliary excretion is a minor route.
Primarily fecal (57%) via biliary excretion as unchanged drug and metabolites; renal excretion accounts for approximately 13% (2-4% unchanged).
