DIPHENHYDRAMINE HYDROCHLORIDE vs X-TROZINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine H1 receptors, reducing allergic symptoms; also exerts anticholinergic, sedative, and antiemetic effects via central and peripheral receptor blockade.
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.
25-50 mg orally or intramuscularly every 4-6 hours as needed; maximum 300 mg per day.
100 mg orally twice daily

Terminal elimination half-life 4–10 hours (mean ~7 hours); prolonged in elderly, hepatic impairment, and with CYP2D6 poor metabolizers.
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.
Renal elimination of metabolites accounts for ~60% of the dose; <5% excreted unchanged. Fecal excretion ~40% via bile.
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.
