EXSEL vs OXISTAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Exsel (selenium sulfide) is an antifungal agent that reduces the production of cutaneous oils and exerts cytostatic effects on epidermal cells. It inhibits the growth of Pityrosporum ovale and other fungi by interfering with oxidative enzyme systems, leading to decreased sebum production and normalization of epidermal turnover.
Oxiconazole is an azole antifungal that inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
1-2 mg orally once daily; maximum dose 2 mg/day.
Apply topically once daily for 2 weeks (tinea pedis, tinea cruris, tinea corporis) or 4 weeks (tinea versicolor).

Terminal half-life: 12-18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 20–30 hours, supporting once-daily topical application.
Renal: ~70% unchanged; biliary/fecal: ~30% as metabolites.
Primarily hepatic metabolism; <1% excreted unchanged in urine; biliary/fecal elimination accounts for ~75% of dose.
