Milrinone (milrinone) — Uses, Dosage, Side Effects & Safety

Drug class: Phosphodiesterase 3 (PDE3) inhibitor; Inotrope; Vasodilator

Overview

Milrinone is a medication used to treat heart failure, especially in situations where other treatments have not worked or when short-term support is needed, such as after heart surgery or during severe heart failure episodes. It helps the heart pump more effectively and relaxes blood vessels, making it easier for the heart to circulate blood. Milrinone works by increasing the strength of the heart's contractions (positive inotropy) and by widening blood vessels (vasodilation). This dual action helps reduce the workload on the heart and improves blood flow to the body. Key points for patients: Milrinone is usually given in a hospital setting through an intravenous (IV) line. It is not a cure for heart failure but provides temporary support. Your healthcare team will closely monitor your heart rate, blood pressure, and other vital signs while you are receiving this medication.
