Medorinone is an inhibitor of cAMP phosphodiesterase activity. Inhibition of cAMP phosphodiesterase by medorinone in cardiac and vascular smooth muscle is a mechanism by which this agent produces both positive cardiac inotropy and vascular smooth muscle relaxation. It inhibits platelet aggregation.
