CHILDREN'S ALLEGRA ALLERGY vs TRIPROLIDINE HYDROCHLORIDE
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.
Competitive antagonist of histamine H1 receptors; inhibits histamine-mediated vasodilation, increased capillary permeability, and bronchoconstriction in allergic reactions.
Fexofenadine 60 mg orally twice daily or 180 mg once daily.
2.5 mg orally every 4-6 hours as needed; maximum 10 mg per 24 hours.

Terminal elimination half-life is approximately 14.4 hours (range 11–17 hours) in healthy adults. In children aged 6–12 years, half-life is similar. Clinical context: allows once-daily dosing.
Terminal elimination half-life approximately 3–4 hours in healthy adults; prolonged in renal impairment (up to 12 hours).
Fexofenadine is excreted primarily unchanged in feces (approximately 80%) and urine (approximately 11%). Biliary excretion accounts for a minor portion.
Renal (primarily as metabolites; ~70% recovered in urine within 24 hours, <5% unchanged). Fecal elimination is minor.
