Terminal half-life: 8-12 hours (average 10 hours); prolonged in hepatic impairment (up to 24 h) and severe renal impairment (up to 18 h).
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.
Renal: 30-50% unchanged; hepatic metabolism: 50-70% (CYP3A4); biliary/fecal: 10-20%.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
