HALOTEX vs SELSUN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Halotex (haloprogin) is a topical antifungal agent that disrupts fungal cell membrane permeability and inhibits ergosterol synthesis, leading to cell death.
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 topically twice daily for 2-4 weeks; tinea pedis may require up to 6 weeks.
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.

Not well characterized; estimated terminal half-life approximately 24-48 hours based on limited data.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily fecal (biliary) as unchanged drug and metabolites; negligible renal excretion (<1%).
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
