Dobutamine is a direct-acting agent whose primary activity results from stimulation of the β 1-adrenoceptors of the heart, increasing contractility and cardiac output. Since it does not act on dopamine receptors to inhibit the release of norepinephrine (another α 1 agonist), dobutamine is less prone to induce hypertension than is dopamine.
The inotropic agent dobutamine is advised only in the short-term use of acutely decompensated heart failure, and has no other uses. [13] Phosphodiesterase inhibitors such as milrinone are sometimes utilized in severe cardiomyopathy.
Some substances do both (e.g. dopamine, dobutamine).

As of 2010 dopexamine was not often administered in cardiac care because other, more well established drugs can accomplish the same effect, other such drugs include epinephrine, dopamine, dobutamine, norepinephrine, and levosimendan. [4]
