CHILDREN'S CLARITIN vs CLARITIN HIVES RELIEF
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.
Selective inverse agonist at histamine H1 receptors, blocking histamine-mediated effects in allergic reactions.

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