CHILDREN'S FEXOFENADINE HYDROCHLORIDE ALLERGY vs X-TROZINE
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 acts as a selective serotonin reuptake inhibitor (SSRI) by binding to the serotonin transporter (SERT) and blocking reuptake of serotonin, thereby increasing serotonergic neurotransmission.
Fexofenadine hydrochloride 60 mg orally twice daily or 180 mg orally once daily.
100 mg orally twice daily

14.4 hours (range 11-16 hours) in healthy adults; prolonged in renal impairment.
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged to 24-36 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Primarily fecal (80%) and renal (11%) as unchanged drug.
Renal excretion accounts for 60-70% of total clearance, predominantly as unchanged drug. Biliary/fecal elimination constitutes 20-30% via P-glycoprotein-mediated transport. Minor metabolism (<10%) via CYP3A4.
