LONITEN vs RAPLON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Minoxidil is a potassium channel opener that causes direct vasodilation of peripheral arteries. It reduces peripheral vascular resistance and blood pressure by hyperpolarizing vascular smooth muscle cells via activation of ATP-sensitive potassium channels.
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.
10 mg orally twice daily, titrated to 40 mg twice daily for hypertension; for heart failure, start at 2.5-5 mg orally twice daily, max 20 mg twice daily.
0.2 mg/kg IV bolus over 30 seconds; may repeat once if necessary after 15 minutes.

Terminal elimination half-life: 4.2 hours (range 3.5–5.5); clinically, half-life extends to 14–23 hours after chronic dosing due to drug accumulation.
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: 85% (12% unchanged, 73% as glucuronide conjugates); biliary/fecal: 3%
Primarily renal excretion of unchanged drug (approximately 80-90% of administered dose within 24 hours); minor biliary/fecal elimination (less than 10%).
