MedKoo CAT#: 326667

CAS#: 81840-15-5

Description: Vesnarinone is a cardiotonic agent, mixed phosphodiesterase 3 inhibitor and ion-channel modifier that has modest, dose-dependent, positive inotropic activity, but minimal negative chronotropic activity. Vesnarinone improves ventricular performance most in patients with the worst degree of heart failure.
