MICONAZOLE 7 vs SELSUN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby 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.
Apply 200 mg (one full applicator) intravaginally once daily 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 half-life 24-30 hours; prolonged in hepatic impairment
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily fecal (~50%) and renal (~<1% unchanged)
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
