Vetmedin® Chewable Tablets is a breakthrough treatment for congestive heart failure in dogs. Since its introduction in 2000, it has been shown to increase both quality of life and length of life in dogs suffering from congestive heart disease, above and beyond previous treatment regimes. Vetmedin® opens up the blood vessels taking blood away from the heart, so reducing the work the heart has to do to pump blood around your dog's body. At the same time, Vetmedin® opens up the blood vessels returning blood to the heart which reduces pressure on the heart. Vetmedin® also differs from other commonly used heart drugs by helping to the heart to pump more efficiently. It is thought that the increase in life expectancy seen in clinical studies is a result of these effects.
