Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole 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 of one applicator (200 mg miconazole nitrate) at bedtime for 3 consecutive 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 20-30 hours for miconazole after systemic absorption, reflecting slow elimination from deep tissue compartments.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Approximately 50% of absorbed dose excreted in feces via biliary elimination; <1% excreted unchanged in urine. Unabsorbed drug from vaginal administration is eliminated in vaginal discharge.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
