Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits squalene epoxidase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Selenium sulfide is an antifungal agent that inhibits the growth of Malassezia species by reducing selenium to elemental selenium, which is toxic to the fungus. It also reduces sebum production via unknown mechanisms.
1% cream applied topically once daily for 2 weeks for tinea pedis, 1 week for tinea corporis/cruris.
Apply 5-10 mL of 2.5% selenium sulfide lotion to affected areas of scalp, lather with water, leave on for 2-3 minutes, then rinse thoroughly. Use twice weekly for 2 weeks, then once weekly for maintenance.

Terminal elimination half-life is approximately 35–40 hours following topical application; long half-life supports once-daily dosing.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily metabolized in the liver; minimal excretion of unchanged drug. Less than 5% of a topical dose is absorbed systemically; excreted in urine and feces as metabolites.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
