CHILDREN'S CLARITIN vs CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY
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.
Fexofenadine is a selective peripheral H1-receptor antagonist. It inhibits histamine release from mast cells and basophils, reducing allergic symptoms.
10 mg orally once daily
Fexofenadine hydrochloride 60 mg orally twice daily or 180 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.
14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
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.
Primarily fecal (80%) and renal (11%) as unchanged drug.
