Dobutamine is indicated for cardiogenic shock and acute heart failure with low cardiac output. It acts as a β1-agonist, increasing myocardial contractility and cardiac output with rapid onset. This leads to improved tissue perfusion and oxygen delivery in critically ill patients. In ICU and cardiology settings, dobutamine is particularly useful when there is evidence of hypoperfusion despite adequate blood pressure. Its titratable infusion allows precise hemodynamic control, making it a reliable first-line inotropic support in acute settings.
