Biochem/physiol Actions

Pimobendan is an inotropic agent with a dual mechanism of action: it increases myocardial contractility by increasing calcium sensitization to troponin C and it promotes vasodilation by inhibiting phosphodiesterase III (PDE3). Pimobendan has been studied for treating heart failure and cardiomyopathy, primarily for veterinary uses.
