Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole nitrate, an imidazole antifungal, 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.
One vaginal suppository (200 mg miconazole nitrate) intravaginally at bedtime for 3 consecutive days; or one applicatorful (5 g) of 4% vaginal cream intravaginally at bedtime for 7 days.
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 30 hours after topical vaginal application; prolonged in hepatic impairment.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily fecal (97%) via biliary excretion; renal excretion of unchanged drug is negligible (<1%).
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
