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 and cytostatic agent. It reduces sebum production and inhibits the growth of Malassezia species by interfering with fungal lipid metabolism and cell wall synthesis. The exact molecular mechanism is not fully elucidated.
165 mg orally once daily.
Topical: 2.5% lotion or shampoo applied to affected area once daily for 7 days; 1% shampoo used once or twice 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 established; due to negligible systemic absorption, a terminal half-life is not clinically relevant. If absorbed, selenium has a long biological half-life of approximately 65–115 days due to incorporation into selenoproteins.
Primarily renal excretion of metabolites; <1% excreted unchanged. Biliary/fecal elimination accounts for ~30% of metabolites.
Selenium sulfide is minimally absorbed after topical application. The small absorbed fraction is excreted renally as selenite or selenate, with fecal excretion of unabsorbed drug accounting for >90% of the dose.
