Terminal elimination half-life is approximately 50 hours (range 40-70 hours), allowing once-daily dosing.
Terminal elimination half-life approximately 7 hours for quetiapine; for metabolite N-desalkylquetiapine (norquetiapine), approximately 12 hours. Steady-state reached within 2 days.
Fecal (approximately 60%) as unchanged drug and metabolites; renal (approximately 13%) as unchanged drug and metabolites.
Primarily hepatic metabolism; <1% excreted unchanged renally. Metabolites excreted in urine (73%) and feces (20%).
