SERPALAN vs SERPANRAY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin at the presynaptic terminal.
Serotonin-dopamine activity modulator; partial agonist at 5-HT1A and D2 receptors, antagonist at 5-HT2A receptors.
100 mg orally twice daily

Terminal elimination half-life is 12-14 hours in adults with normal renal function; prolonged to 24-36 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 60 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 62 hours following oral administration, allowing for once-daily dosing.
Primarily renal elimination (60-70% unchanged drug), with 20-30% biliary/fecal excretion as metabolites; less than 10% excreted unchanged in feces.
Primarily hepatic metabolism via CYP1A2 and CYP3A4, with 18% excreted unchanged in urine and 26% in feces as metabolites.
