Overview
Pimobendan, commonly known by its brand name Vetmedin, is a veterinary cardiac drug primarily used in dogs to manage heart failure. It is an inodilator, meaning it has both inotropic and vasodilator effects, which help the heart pump more efficiently.
How It Works
Pimobendan works by increasing the heart muscle's ability to contract (positive inotropic effect) and by dilating blood vessels (vasodilation). This dual action reduces the workload on the heart and improves cardiac output.
