CHILDREN'S CLARITIN vs TRIPROLIDINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loratadine is a long-acting second-generation antihistamine that selectively antagonizes peripheral histamine H1 receptors, thereby inhibiting the effects of histamine released from mast cells and basophils, reducing allergic symptoms.
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.

The terminal elimination half-life of loratadine is 8-14 hours (mean 11 hours) in healthy adults; for the active metabolite descarboethoxyloratadine, half-life is 17-24 hours (mean 20 hours). This supports once-daily dosing.
Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Loratadine is primarily eliminated via hepatic metabolism, with approximately 80% of the dose excreted as metabolites in urine (40%) and feces (40%). Less than 1% is excreted unchanged in urine.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
