DescriptionA positive inotropic cardiotonic agent with vasodilator properties. It inhibits cAMP phosphodiesterase activity in myocardium and vascular smooth muscle. Milrinone is a derivative of amrinone and has 20-30 times the ionotropic potency of amrinone. [PubChem]
  • 1,6-Dihydro-2-methyl-6-oxo(3,4'-bipyridine)-5-carbonitrile
  • Milrinona
  • Milrinone
  • Milrinonum
SaltsMilrinone Lactate
Brand Names
  • Apo-milrinone Injectable
  • Milrinone Injection
  • Milrinone Lactate
  • Milrinone Lactate In Dextrose
  • Milrinone Lactate Injection
Affected OrganismHumans and other mammals
IndicationIndicated for the treatment of congestive heart failure.
PharmacologyMilrinone, a synthetic dimethylxanthine derivative structurally related to theophylline and caffeine, is used in the treatment of peripheral vascular diseases and in the management of cerebrovascular insufficiency, sickle cell disease, and diabetic neuropathy.
Mechanism of actionMilrinone inhibits erythrocyte phosphodiesterase, resulting in an increase in erythrocyte cAMP activity. Subsequently, the erythrocyte membrane becomes more resistant to deformity. Along with erythrocyte activity, Milrinone also decreases blood viscosity by reducing plasma fibrinogen concentrations and increasing fibrinolytic activity.
Route of administrationIntravenous
