HIDE SMILES / InChI
Levosimendan (Simdax) is a novel intravenous agent that exerts inotropic effects through sensitization of myofilaments to calcium and vasodilator effects by binding to cardiac troponin C in a calcium-dependent manner. It also has a vasodilatory effect, by opening adenosine triphosphate (ATP)-sensitive potassium channels in vascular smooth muscle to cause smooth muscle relaxation. Unlike other calcium sensitizing compounds, the binding of levosimendan is highly dependent on the intracellular concentration of calcium, such that calcium sensitivity is enhanced only when the calcium level is elevated. Levosimendan is licensed for the treatment of decompensated heart failure in many countries but not in North America. This drug also passed phase III clinical trials for the prevention of low cardiac output syndrome in pediatric patients after open heart surgery.

Sample Use Guides

0.2 micrograms/kg/min is administered intravenously without bolus for 6 hours every two weeks.
Route of Administration: Intravenous
Levosimendan down-regulates the expression of the pro-thrombotic and anti-fibrinolytic biomolecules TF and PAI-1 in activated human endothelial cells. Human heart microvascular endothelial cells (HHMEC) and human umbilical vein endothelial cells (HUVEC) were treated with interleukin-1β (IL-1β) (200U/mL) or thrombin (5U/mL) and co-treated with or without levosimendan (0.1-10μM) for 2-24h. In addition, flow experiments were performed. Effects on plasminogen activator inhibitor-1 (PAI-1) and tissue factor (TF) expression and activity were measured by rt-PCR, specific ELISA and flow cytometry.
