LOTRIMIN vs LOTRIMIN AF
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.
Inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
Topical: Apply twice daily (morning and evening) to affected area for 2-4 weeks. Intravaginal: One 200 mg suppository vaginally at bedtime for 3 days, or one 500 mg vaginal tablet as a single dose.

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 of absorbed clotrimazole is approximately 3.5–4 hours, but this is clinically irrelevant due to negligible systemic absorption after topical application.
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.
Less than 1% of topical clotrimazole is absorbed; absorbed drug is metabolized in the liver to inactive metabolites and excreted primarily in feces (approximately 69%) and urine (approximately 21%) via biliary and renal routes.
