Not applicable for systemic elimination; local retention on hair/scalp lasts until next wash (typically 24-48 hours).
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
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.
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
