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).
8.4 hours (range 3-20 hours) for loratadine; 28 hours (range 8.8-92 hours) for active metabolite desloratadine, allowing once-daily dosing.
Renal: 30-50% unchanged; hepatic metabolism: 50-70% (CYP3A4); biliary/fecal: 10-20%.
Renal: ~40% as metabolites, <1% unchanged; Fecal: ~40%; Biliary: minor contribution.
