brand name
Dopacard (Fisons).
Clinical Use
Inotropic support in exacerbations of heart failure and
heart failure associated with cardiac surgery
Drug interactions
Potentially hazardous interactions with other drugs
Anaesthetics: risk of ventricular arrhythmias with
isoflurane - avoid.
Antidepressants: risk of hypertensive crisis with
MAOIs and moclobemide.
Beta-blockers: risk of severe hypertension
Dopaminergics: avoid with rasagiline.
Sympathomimetics: effects of adrennoradrenaline possibly enhanced.
Metabolism
Dopexamine is rapidly eliminated from blood with a halflife of approximately 6-7 minutes in healthy volunteers
and around 11 minutes in patients with cardiac failure.
Subsequent elimination of the metabolites is by urinary
and biliary excretion.
