CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs CLARITIN HIVES RELIEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fexofenadine is a selective peripheral H1-receptor antagonist. It inhibits histamine release from mast cells and basophils, reducing allergic symptoms.
Selective inverse agonist at histamine H1 receptors, blocking histamine-mediated effects in allergic reactions.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
10 mg orally once daily

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
8.4 hours (range 3-20 hours) for loratadine; 28 hours (range 8.8-92 hours) for active metabolite desloratadine, allowing once-daily dosing.
Primarily fecal (80%) and renal (11%) as unchanged drug.
Renal: ~40% as metabolites, <1% unchanged; Fecal: ~40%; Biliary: minor contribution.
