Levosimendan is a calcium sensitizer that can cause increased cardiac contractility by binding troponin C, promotes vasodilation by activating ATP-sensitive potassium channels on vascular smooth muscle cells, and performs a cardioprotective function by prompting the opening of mitochondrial potassium channels in cardiomyocytes. It also has been reported to inhibit phosphodiesterases 3 and 4 in left ventricular cardiac tissue.
