Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective histamine H1 receptor antagonist; inhibits histamine-mediated allergic and inflammatory responses.
Selective peripheral H1 receptor antagonist; inhibits histamine release from mast cells.

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 is 8–14 hours (mean ~12 hours) for desloratadine (active metabolite); parent loratadine half-life ~3–20 hours (mean ~8 hours). Clinically, once-daily dosing maintains steady state in 5–7 days.
Renal: 30-50% unchanged; hepatic metabolism: 50-70% (CYP3A4); biliary/fecal: 10-20%.
Renal (approximately 40% as metabolites), biliary/fecal (approximately 60% as metabolites). Less than 1% excreted unchanged in urine.
