For short term treatment of acutely decompensated severe chronic heart failure (CHF). Also being investigated for use/treatment in heart disease.
Levosimendan is a new Ca2+-sensitizing inotropic agent. Ca2+ sensitizers represent a new class of inotropic agents, which overcome the disadvantages associated with currently available inotropic agents in as they are not associated with an increased risk of arrhythmias, cell injury and death due to Ca2+ overload in myocardial cells; they do not increase the activation energy; and they have the potential to reverse contractile dysfunction under pathophysiologic conditions, such as acidosis or myocardial stunning. Levosimendan has not been approved for use in the U.S. or Canada.
Vasodilator Agents
Drugs used to cause dilation of the blood vessels. (See all compounds classified as Vasodilator Agents.)
Cardiotonic Agents
Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE). (See all compounds classified as Cardiotonic Agents.)
Phosphodiesterase 3 Inhibitors
Compounds that specifically inhibit PHOSPHODIESTERASE 3. (See all compounds classified as Phosphodiesterase 3 Inhibitors.)

Absorption
The bioavailability of oral levosimendan is 85 ± 6% in healthy volunteers and 84 ± 4% in patients.
Complete metabolism, with some active metabolites (OR-1855 and OR-1896) possibly extending the drug's haemodynamic effects.
Eliminination half-life is approximately 1 hour.
Levosimendan appears to increase myofilament calcium sensitivity by binding to cardiac troponin C in a calcium-dependent manner. This stabilizes the calcium-induced conformational change of troponin C, thereby (1) changing actin-myosin cross-bridge kinetics apparently without increasing the cycling rate of the cross-bridges or myocardial ATP consumption, (2) increasing the effects of calcium on cardiac myofilaments during systole and (3) improving contraction at low energy cost (inotropic effect). Calcium concentration and, therefore, sensitization decline during diastole, allowing normal or improved diastolic relaxation. Levosimendan also leads to vasodilation through the opening of ATP-sensitive potassium channels. By these inotropic and vasodilatory actions, levosimendan increases cardiac output without increasing myocardial oxygen demand. Levosimendan also has a selective phosphodiesterase (PDE)-III inhibitory action that may contribute to the inotropic effect of this compound under certain experimental conditions. It has been reported that levosimendan may act preferentially as a Ca2+ sensitizer at lower concentrations, whereas at higher concentrations its action as a PDE-III inhibitor becomes more prominent in experimental animals and humans.
