Amrinone (generic: inamrinone) is a prescription medication used to treat congestive heart failure. Amrinone belongs to a group of drugs called cardiac inotropic agents, which help the heart increase its ability to beat. It also relaxes the blood vessels so the heart does not have to pump as hard.

This medication is available in an injectable form to be given directly into a vein (IV) by a healthcare professional.

Common side effects of Amrinone include upset stomach, lowered platelet counts, and a sudden drop in blood pressure.
