Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Griseofulvin binds to and disrupts microtubule function by inhibiting spindle formation and mitosis in dermatophytes, leading to inhibition of fungal cell division.
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.
165 mg orally once daily.
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 9-24 hours; dependent on formulation and absorption rate. Steady-state achieved within 4-5 days.
Not well defined due to minimal systemic absorption; topical application yields negligible plasma levels.
Primarily renal excretion of metabolites; <1% excreted unchanged. Biliary/fecal elimination accounts for ~30% of metabolites.
Selenium sulfide is minimally absorbed; absorbed portions are excreted renally (approx. 80-90%) and fecally (10-20%).
