Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
Loratadine is a selective antagonist of peripheral histamine H1 receptors, reducing allergic response symptoms by inhibiting histamine release from mast cells.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed, up to a maximum of 80 mg/day.
10 mg orally once daily.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life: 8–28 hours (mean ~14 hours for loratadine; active metabolite desloratadine: 14–26 hours). Context: Allows once-daily dosing; half-life extended in hepatic impairment.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Renal (approximately 40% as metabolites) and fecal (approximately 40% as metabolites). Parent drug and active metabolite (desloratadine) are excreted in urine (27% total) and feces (40% total).
