CHILDREN'S CLARITIN vs DISOMER
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 dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
10 mg orally once daily
Adults: 1 mg orally once daily.

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.
12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
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: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
