	Milrinone is a phosphodiesterase III inhibitor, which increases cardiac contractility and induces both peripheral and pulmonary vasodilation. Its primary indication is for short-term treatment of acute decompensated heart failure with reduced ejection fraction. Milrinone is more likely to cause hypotension and less likely to cause arrhythmias when compared to other inotropes, such as dobutamine and dopamine.<ref>{{Cite journal\|last=Jentzer\|first=Jacob C.\|last2=Coons\|first2=James C.\|last3=Link\|first3=Christopher B.\|last4=Schmidhofer\|first4=Mark\|date=2014-11-28\|title=Pharmacotherapy Update on the Use of Vasopressors and Inotropes in the Intensive Care Unit\|url=http://dx.doi.org/10.1177/1074248414559838\|journal=Journal of Cardiovascular Pharmacology and Therapeutics\|volume=20\|issue=3\|pages=249–260\|doi=10.1177/1074248414559838\|issn=1074-2484}}</ref>		'''Milrinone''' is a phosphodiesterase III inhibitor, which increases cardiac contractility and induces both peripheral and pulmonary vasodilation.

	Milrinone is an inotrope and vasodilator without significant chronotropic activity. Milrinone selectively inhibits phosphodiesterase III, preventing the breakdown of cAMP in cardiac myocytes and smooth muscle cells. This preserved cAMP increases protein kinase A activity, leading to phosphorylation of calcium ion channels in the sarcoplasmic reticulum and increasing calcium availability in myocyte sarcomere. The aforementioned increased calcium availability results in enhanced cardiac inotropy and chronotropy. In vascular smooth muscle cells, phosphodiesterase III inhibition promotes vasodilation and reduces systemic vascular resistance. Similarly, it decreases pulmonary vascular resistance. <ref>{{Cite journal\|last=Dobashi\|first=Shintaro\|last2=Watanabe\|first2=Ippei\|last3=Nakanishi\|first3=Rine\|last4=Hisatake\|first4=Shinji\|last5=Kiuchi\|first5=Shunsuke\|last6=Kabuki\|first6=Takayuki\|last7=Oka\|first7=Takashi\|last8=Fujii\|first8=Takahiro\|last9=Ikeda\|first9=Takanori\|date=2019-12-21\|title=Comparing the effects of milrinone and olprinone in patients with congestive heart failure\|url=http://dx.doi.org/10.1007/s00380-019-01543-6\|journal=Heart and Vessels\|volume=35\|issue=6\|pages=776–785\|doi=10.1007/s00380-019-01543-6\|issn=0910-8327}}</ref>		Milrinone is an inotrope and vasodilator without significant chronotropic activity.
