Fexofenadine Hydrochloride API
Mechanism of Action
Fexofenadine hydrochloride, the major active metabolite of terfenadine, is an antihistamine with selective H1-receptor antagonist activity. Both enantiomers of fexofenadine hydrochloride displayed approximately equipotent antihistaminic effects. Fexofenadine hydrochloride inhibited antigen-induced bronchospasm in sensitized guinea pigs and histamine release from peritoneal mast cells in rats. The clinical significance of these findings is unknown. In laboratory animals, no anticholinergic or alpha1-adrenergic blocking effects were observed. Moreover, no sedative or other central nervous system effects were observed. Radiolabeled tissue distribution studies in rats indicated that fexofenadine does not cross the blood-brain barrier.
ALLEGRA is an H1-receptor antagonist indicated for:
- Relief of symptoms associated with seasonal allergic rhinitis in patients ≥ 2 years of age
- Treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in patients ≥ 6 months of age
