8.4 hours (range 3-20 hours) for loratadine; 28 hours (range 8.8-92 hours) for active metabolite desloratadine, allowing once-daily dosing.
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: ~40% as metabolites, <1% unchanged; Fecal: ~40%; Biliary: minor contribution.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
