Caldaret is primarily used in the field of cardiology as a calcium sensitizer. It enhances the sensitivity of cardiac muscle cells to calcium, which improves myocardial contractility without significantly increasing oxygen demand. This makes it particularly useful in the management of heart failure, where it helps to strengthen the heart's pumping ability. Additionally, Caldaret has shown potential in protecting the heart during cardiac surgery or procedures that may cause ischemia-reperfusion injury, reducing damage to heart tissue. Its mechanism of action also supports its use in stabilizing heart function in critical care settings, offering a therapeutic option for patients with compromised cardiac performance.
