Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal cytochrome P450 14α-demethylase, 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.
Intravaginal administration: 100 mg (one applicatorful of 2% cream) once daily for 3 days; or 100 mg (one suppository) once daily for 3 days; or 5 g (one applicatorful of 4% cream) as a single dose.
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 half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
