CHILDREN'S ALLEGRA ALLERGY vs TAVIST
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.
Antihistamine; selective inverse agonist at histamine H1 receptors, blocking histamine-mediated allergic and inflammatory responses.
Fexofenadine 60 mg orally twice daily or 180 mg once daily.
1.34 mg orally twice daily; maximum 8.04 mg/day.

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 is 12-15 hours in healthy adults; prolonged in renal/hepatic impairment.
Fexofenadine is excreted primarily unchanged in feces (approximately 80%) and urine (approximately 11%). Biliary excretion accounts for a minor portion.
Renal excretion of metabolites (approx. 60%) and unchanged drug (<5%); biliary/fecal elimination accounts for about 40%.
