“Formulated for cats and dogs experiencing these conditions:”
Heart Conditions in Dogs :
Supported by Pimobendan
Mitral Valve Disease (MVD): Helps reduce cardiac workload and supports improved heart function.
Dilated Cardiomyopathy (DCM): Improves contraction strength in enlarged, weakened hearts.
Congestive Heart Failure (CHF): Supports dogs with heart failure by improving circulation and reducing clinical burden, helping maintain quality of life.
Benefits of HeartRx with Pimobendan :
Improves Cardiac Performance: Enhances heart muscle contraction and pumping efficiency.
Reduces Cardiac Workload: Vasodilation helps decrease resistance and strain on the heart.
Supports Longer Survival & Better
Quality of Life: Clinically shown to delay progression of CHF when used as part of veterinary-managed treatment.
HeartRx™
HeartRx™ contains pimobendan, a clinically proven medication used to support dogs with heart disease, especially those with congestive heart failure (CHF) caused by mitral valve disease (MVD) or dilated cardiomyopathy (DCM).
Pimobendan works by improving the strength of heart muscle contractions while also widening blood vessels, helping the heart pump more efficiently and reducing strain on the cardiovascular system. This dual action helps improve circulation, slow disease progression, and support a better quality of life for dogs with heart conditions.
When used under veterinary guidance, HeartRx™ plays an important role in long-term cardiac management and supportive care for affected dogs.
Active Ingredients
Pimobendan – 1.25 mg / 5 mg
A clinically proven cardiac medication that improves heart muscle contraction and widens blood vessels, helping the heart pump more efficiently and reducing cardiac workload.
