CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs KETOTIFEN FUMARATE
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 and mast cell stabilizer; inhibits release of histamine and other mediators from mast cells; also blocks histamine H1 receptors.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
1 mg orally twice daily; ophthalmic: 1 drop in each eye every 8-12 hours.

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
Terminal half-life 12-24 hours (mean 18 hours); requires twice-daily dosing after initial titration.
Primarily fecal (80%) and renal (11%) as unchanged drug.
Renal (50-70% as conjugates, <2% unchanged), fecal (<10%), with enterohepatic circulation.
