| 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. |
