Milrinone is a medication primarily used to treat heart failure. It works by increasing the heart's ability to pump blood and relaxing blood vessels, which helps improve blood flow. This can be particularly beneficial for patients with severe heart conditions who need short-term support. Typically administered through an intravenous (IV) line, Milrinone is often used in hospital settings. It is important for healthcare providers to monitor patients closely while on this medication, as it can have side effects, including low blood pressure and irregular heart rhythms.
