CAS 141505-33-1: Levosimendan
Description:Levosimendan is a pharmacological agent primarily used in the treatment of acute heart failure. It is classified as a calcium sensitizer, which enhances cardiac contractility without significantly increasing myocardial oxygen demand. This unique mechanism of action distinguishes it from traditional inotropic agents. Levosimendan also possesses vasodilatory properties, which help reduce preload and afterload on the heart, further improving cardiac output. The substance is characterized by its ability to stabilize the troponin complex, leading to increased calcium sensitivity in cardiac myocytes. Its chemical structure includes a chiral center, resulting in the presence of enantiomers, with the (R)-enantiomer being the active form. Levosimendan is typically administered intravenously and has a relatively short half-life, necessitating careful monitoring during treatment. Common side effects may include hypotension, headache, and gastrointestinal disturbances. Overall, Levosimendan represents a valuable therapeutic option in managing acute decompensated heart failure, particularly in patients who may not tolerate conventional therapies.
