HIWOLFIA vs RAPLON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective agonist at central nervous system GABA-A receptors, enhancing inhibitory neurotransmission.
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.
Not established; investigational agent.
0.2 mg/kg IV bolus over 30 seconds; may repeat once if necessary after 15 minutes.

Terminal elimination half-life is 18 hours (range 14-22 hours). Clinically, this supports once-daily dosing in most patients; however, in renal impairment (CrCl <30 mL/min), half-life extends to 40 hours, requiring dose adjustment.
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).
Renal excretion accounts for 70% of elimination, with 30% via biliary/fecal routes. Of the renal component, 90% is eliminated unchanged, 10% as metabolites.
Primarily renal excretion of unchanged drug (approximately 80-90% of administered dose within 24 hours); minor biliary/fecal elimination (less than 10%).
