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.
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. . Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocar

This in turn may result in fewer effects in the central nervous system as well as a lower risk of neuropsychiatric side effects. [44] Only small amounts of atenolol are said to enter the brain. [ 2 ] [ 3 ] The brain-to-blood ratio of atenolol was 0.2 : 1 in one study, whereas the ratio for propranolol was 33 : 1 in the same study.
