| In vitro | Levosimendan is a calcium sensitizer acting through calcium-dependent binding to cardiac troponin C (cTnC). Levosimendan at 3 μM decreases the value of Ca50 from 2.73μM to 1.19 μM. levosimendan exhibits its calcium sensitizing effect through calcium-dependent binding to the N-terminal domain of cTnC. [1] Levosimendan significantly hyperpolarizes resting potential of rat mesenteric arterial myocytes with an EC50 of 2.9 μM and maximal effect (19.5 mV) at 10 μM, probably through activation of a glibenclamide-sensitive K+ channel. [2] Levosimendan has inotropic and lusitropic actions in failing human myocardium, with average maximum increase in twitch tension of 47% at a levosimendan concentration of 0.8 μM. [3] Levosimendan causes rapid dose-dependent improvement in hemodynamic function in patients with decompensated heart failure. [4] |
|
| In vivo | Levosimendan at low concentrations (0.03 to 0.1 μM) acts preferably as a Ca2+ sensitizer, whereas at higher concentrations (0.1 to 0.3 μmol/L) its action as a phosphodiesterase inhibitor contributes to the positive inotropic effect. [5] |
