CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs ZERVIATE
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.
ZERVIATE (cetirizine ophthalmic solution) contains cetirizine, a selective histamine H1 receptor antagonist. It inhibits histamine-induced vasodilation and increased vascular permeability, leading to reduction of ocular itching associated with allergic conjunctivitis.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
1 drop in each affected eye twice daily (approximately 8 hours apart).

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
Terminal elimination half-life is approximately 3 hours; clinical context: supports twice-daily topical ocular dosing for allergic conjunctivitis.
Primarily fecal (80%) and renal (11%) as unchanged drug.
Primarily renal excretion of unchanged drug (approximately 70%) and metabolites; biliary/fecal elimination accounts for less than 20%.
