The haemodynamic and myocardial effects of dopexamine: a new beta 2‐ adrenoceptor and dopaminergic agonist.

Abstract
Dopexamine increases inotropic state and rate of relaxation independent of changes in heart rate. Dopexamine has a chronotropic effect and results in a decrease in systemic vascular resistance. Dopexamine has a spectrum of action that should be useful in patients with severe heart failure.
