CHILDREN'S ALLEGRA ALLERGY vs FEXOFENADINE HYDROCHLORIDE HIVES
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.
Fexofenadine hydrochloride is a selective peripheral H1-receptor antagonist. It blocks the action of histamine at the H1 receptor, preventing histamine-mediated symptoms such as itching, sneezing, rhinorrhea, and urticaria.
Fexofenadine 60 mg orally twice daily or 180 mg once daily.

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 14.4 hours (range 11–17 hours) in healthy adults. Clinically, this supports twice-daily dosing for symptomatic relief.
Fexofenadine is excreted primarily unchanged in feces (approximately 80%) and urine (approximately 11%). Biliary excretion accounts for a minor portion.
Approximately 95% of the dose is excreted unchanged in feces (80%) and urine (15%). Fexofenadine undergoes minimal hepatic metabolism (<5%).
