Dobutamine is a medication primarily used to treat heart failure and improve heart function. It works by stimulating the heart's beta-1 adrenergic receptors, which increases the strength of heart contractions and helps the heart pump more effectively. This can be particularly beneficial for patients with weakened heart muscles. Typically administered through an intravenous (IV) line in a hospital setting, dobutamine can help improve blood flow and reduce symptoms of heart failure. It is often used in emergency situations or during diagnostic tests to assess heart function. However, it may have side effects, including increased heart rate and blood pressure.
