CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs X-TROZINE L.A.
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.
X-TROZINE L.A. is a piperazine derivative that acts as a centrally acting alpha-2 adrenergic agonist, reducing sympathetic outflow from the brainstem, leading to decreased peripheral vascular resistance and lowered blood pressure.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
250 mg orally once daily. May be increased to 500 mg once daily if needed.
