    Background
    
    Milrinone is a selective inhibitor of phosphodiesterase 3 (PDE-3) with a IC50 value of 56±12nM [1]Milrinone has been noted to inhibit both members of the PDE3 family, PDE3A, which is prominent in heart, vascular smooth muscle, and platelets, as well as PDE3B, which is prominent in fat, liver, and pancreatic islets. Milrinone has shown the effect of concentration-dependent inhibition of PDE3 on the photolabelling with a IC50 value of 56±12nM. In addition, Milrinone has been reported to increase the accumulation of [3H]cAMP with a EC50 value of 5329±970nM in platelets. Apart from these, Milrinone has been revealed to have positive inotropic and vasodilatiry activities and thus used in clinical practice for short-trem treatment of patients who have the acute decompensated heart failure [1, 2].
