RAPLON vs SERPALAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
RAPLON (levosimendan) is a calcium sensitizer that increases myocardial contractility by sensitizing troponin C to calcium, and it also opens ATP-sensitive potassium channels, causing vasodilation.
Selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin at the presynaptic terminal.
0.2 mg/kg IV bolus over 30 seconds; may repeat once if necessary after 15 minutes.
100 mg orally twice daily

Terminal elimination half-life is approximately 1.5-2.5 hours in patients with normal renal function; prolonged in renal impairment (up to 6-8 hours in end-stage renal disease).
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).
Primarily renal excretion of unchanged drug (approximately 80-90% of administered dose within 24 hours); minor biliary/fecal elimination (less than 10%).
Primarily renal elimination (60-70% unchanged drug), with 20-30% biliary/fecal excretion as metabolites; less than 10% excreted unchanged in feces.
