CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs PHENETRON
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.
Phenetron is an antihistamine that competes with histamine for H1-receptor sites, blocking histamine-mediated effects in the respiratory tract, vascular system, and gastrointestinal tract. It also exhibits anticholinergic and sedative properties.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
Adults: 50 mg intramuscularly every 6 hours as needed.
