| Name | Levosimendan |
| Description | Levosimendan (OR1259) is a calcium sensitizer used in the management of acutely decompensated congestive heart failure. It increases the sensitivity of the heart to calcium, thus increasing cardiac contractility without a rise in intracellular calcium. Levosimendan exerts its effect by increasing calcium sensitivity of myocytes by binding to cardiac troponin C in a calcium-dependent manner. |
| In vitro | Levosimendan caused contraction and relaxation of failing human cardiomyocytes, with a mean maximum increase in twitch tension of 47% at 0.8 μM Levosimendan.Levosimendan induced a rapid dose-dependent increase in hemodynamic functions in patients with compensated heart failure.Levosimendan caused a significant hyperpolarization (EPS) of resting potential (EPS) in rat mesenteric artery myocytes. The resting potential of rat mesenteric artery myocytes was markedly hyperpolarized by Levosimendan (EC50: 2.9 μM), with a maximal effect at 10 μM (19.5 mV), which may be produced by activation of glibenclamide-sensitive K+ channels.Levosimendan (3 μM) reduced the Ca50 from 2.73 μM to 1.19 μM. |
