CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs CLARITIN
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.
Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1 receptor antagonistic activity. It inhibits histamine release from mast cells and reduces allergic responses.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
10 mg orally once daily for adults and children ≥6 years.
