Excerpt
Levosimendan is used intravenously for the management of heart failure. At the therapeutic dose, levosimendan acts predominantly as a calcium sensitizer and ATP-sensitive K+-channel (KATP-channel) opener. It binds directly to the calcium-dependent site on troponin C, stabilizing the calcium-induced conformational change and enhances the calcium sensitivity of the cardiac myofilaments. The advantages of a calcium sensitizer over dobutamine is the lack of intracellular calcium overload and that it acts without increasing the energy demand for handling intracellular calcium. …
