WebRole of dopamine in congestive heart failure: a contemporary appraisal The pharmacodynamic effects of dopamine, an endogenous catecholamine, are complex and mediated through selective activation of specific dopaminergic and adrenergic receptors in a dose dependent manner. WebAs doses of dobutamine increase, β2‐ and α1adrenergic receptors are similar to dopamine. It does not generate the same degree of vasoconstriction that is created by dopamine. Unlike dopamine, dobutamine does not have any effect on the α2‐adrenergic receptors. Dobutamine is preferred when there is a need to improve low cardiac output.
