SELSUN vs TIOCONAZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Inhibition of fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
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.
Topical: Apply 1% cream, lotion, or solution to affected area twice daily for 2-4 weeks. Vaginal: Insert 1 applicatorful of 6.5% ointment intravaginally at bedtime as a single dose.

"The risk or severity of adverse effects can be increased when Tioconazole is combined with Tranilast."

Clinical Note
moderateTioconazole + Nimesulide
"The risk or severity of adverse effects can be increased when Tioconazole is combined with Nimesulide."
Clinical Note

Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Terminal elimination half-life is approximately 24–30 hours after topical application, reflecting slow systemic clearance of absorbed fraction.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
Primarily fecal (minimally absorbed; <5% absorbed dose excreted renally as metabolites); topically applied tioconazole is largely unabsorbed.
