Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inverse agonist at histamine H1 receptors, blocking histamine-mediated effects in allergic reactions.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
10 mg orally once daily
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.

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 approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Renal: ~40% as metabolites, <1% unchanged; Fecal: ~40%; Biliary: minor contribution.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
