CLOTRIMAZOLE vs SELENIUM SULFIDE
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.
Selenium sulfide is an antifungal and cytostatic agent. It reduces sebum production and inhibits the growth of Malassezia species by interfering with fungal lipid metabolism and cell wall synthesis. The exact molecular mechanism is not fully elucidated.
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.
Topical: 2.5% lotion or shampoo applied to affected area once daily for 7 days; 1% shampoo used once or twice weekly for maintenance.

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.
Not established; due to negligible systemic absorption, a terminal half-life is not clinically relevant. If absorbed, selenium has a long biological half-life of approximately 65–115 days due to incorporation into selenoproteins.
Primarily fecal (biliary) as unchanged drug and metabolites; minimal renal excretion (<1% unchanged).
Selenium sulfide is minimally absorbed after topical application. The small absorbed fraction is excreted renally as selenite or selenate, with fecal excretion of unabsorbed drug accounting for >90% of the dose.
