Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life of loratadine is 8.4 hours (range 3–20 hours); for its active metabolite descarboethoxyloratadine, it is 24.9 hours (range 8.8–45 hours). Clinical context: Steady-state concentrations are achieved by day 5.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
