Action
Description: Levosimendan is a cardiac inotrope and vasodilator w/ Ca-sensitising properties. It is dependent on Ca concentration and sensitises tropin C to Ca. It also opens ATP-sensitive K channels on vascular smooth muscle which causes coronary and systemic vasodilation.
Pharmacokinetics: Absorption: Well absorbed. Bioavailability: 85%. Time to peak plasma concentration: 1-2 days. Distribution: Plasma protein binding: Approx 98% (mainly albumin); approx 40% (active metabolite). Metabolism: Extensively metabolised to its active metabolite (OR-1855 and OR-1896) which are interconverted by acetylation and de-acetylation. Excretion: Via urine and faeces as metabolites and unchanged drug (small amount). Elimination half-life: Approx 1 hr. |
