CHILDREN'S ALLEGRA ALLERGY vs POLARAMINE
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, blocking the effects of histamine in the respiratory tract, vasculature, and gastrointestinal tract.
Fexofenadine 60 mg orally twice daily or 180 mg once daily.
4-8 mg orally every 6-8 hours; maximum 24 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: 20-25 hours (range 14-36 hours). Clinical context: Supports once-daily dosing for chronic allergic symptoms; accumulation possible with hepatic impairment.
Fexofenadine is excreted primarily unchanged in feces (approximately 80%) and urine (approximately 11%). Biliary excretion accounts for a minor portion.
Primarily renal (40-60% as unchanged drug and metabolites), with minor biliary/fecal elimination
