CLOTRIMAZOLE vs LAMISIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clotrimazole inhibits fungal cytochrome P450 14α-demethylase, disrupting ergosterol biosynthesis and increasing membrane permeability.
Allylamine antifungal that inhibits squalene epoxidase, an enzyme in the ergosterol biosynthesis pathway, leading to accumulation of squalene and disruption of fungal cell membrane function.
Topical: Apply thin layer to affected area twice daily for 2-4 weeks. Oral troche: 10 mg troche dissolved slowly in mouth 5 times daily for 14 days. Vaginal: One 100 mg suppository intravaginally at bedtime for 7 days, or 200 mg suppository for 3 days, or 500 mg single dose.
250 mg orally once daily for 2-6 weeks for dermatophyte infections; 250 mg orally once daily for 12 weeks for onychomycosis.

Clinical Note
moderateClotrimazole + Tranilast
"The risk or severity of adverse effects can be increased when Clotrimazole is combined with Tranilast."
Clinical Note
moderateClotrimazole + Tolfenamic acid
"The risk or severity of adverse effects can be increased when Clotrimazole is combined with Tolfenamic acid."
Clinical Note
moderateClotrimazole + Nimesulide
"The risk or severity of adverse effects can be increased when Clotrimazole is combined with Nimesulide."
Clinical Note
moderateTerminal half-life is approximately 3-6 hours; due to rapid hepatic metabolism and extensive tissue distribution, clinical effects persist longer than plasma levels suggest.
Terminal elimination half-life is approximately 17-24 hours in healthy adults. However, it can prolong to about 36-40 hours in patients with renal or hepatic impairment. The prolonged half-life allows for once-daily dosing. Due to extensive tissue distribution, the functional half-life (terminal phase from tissues) may be longer.
Primarily fecal (biliary) as unchanged drug and metabolites; minimal renal excretion (<1% unchanged).
Approximately 70% of the administered dose is excreted in the urine as metabolites, with less than 5% as unchanged drug. About 20% is eliminated via feces. Terbinafine undergoes extensive hepatic metabolism; renal elimination of metabolites is the primary route.
