Terminal elimination half-life: 9–24 hours (mean ~14 hours). Clinical context: Steady-state achieved in 3–5 days; once-daily dosing is effective due to prolonged half-life.
Not applicable for systemic elimination; local retention on hair/scalp lasts until next wash (typically 24-48 hours).
Renal: <1% as intact drug; fecal: >99% as metabolites (mainly 6-demethylgriseofulvin glucuronide) via bile; negligible biliary excretion of parent compound.
Renal (urine): <1% unchanged; biliary/fecal: <1% as parent compound; majority remains on hair/scalp and is removed via washing and shedding. Systemic absorption negligible.
