ORAVIG vs SELSUN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole, an azole antifungal, 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.
ORAVIG (miconazole) 50 mg buccal tablet applied once daily to the upper gum region (canine fossa) for 14 consecutive days. The tablet is placed with the rounded side against the gum and held in place for 30 seconds to ensure adhesion.
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 24 hours, supporting once-daily buccal administration for sustained local oropharyngeal concentrations.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily fecal (approximately 52%) with 39% of the dose recovered in urine; less than 0.5% of the dose is excreted unchanged in urine.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
