CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs ZADITOR
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 histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
1 drop in each affected eye twice daily, approximately 6-8 hours apart.

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
Primarily fecal (80%) and renal (11%) as unchanged drug.
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
