Overview

Dopexamine is a synthetic analogue of dopamine. Despite this, it is a β1 and β2-adrenergic receptor agonist.[1] Its action at dopamine receptor D1 mediates relaxation of vascular smooth muscle in renal, mesenteric, cerebral and coronary arteries. Mild action at D2 receptors decreases noradrenaline release.[2]

Use in sepsis has been proposed.[3]

It is used as an inotropic agent in cardiac failure.[4] Side effects include arrhythmia, tremor, angina and flushing.
