Pimobendan is used in the treatment of Heart Failure.
How Pimobendan works
Pimobendan contains pimobendan, a medicine that works to improve heart performance. It increases the heart’s pumping strength by making the heart muscle more sensitive to calcium, helping it contract more efficiently without increasing oxygen demand. At the same time, it widens blood vessels by inhibiting an enzyme called phosphodiesterase III, reducing the workload on the heart and improving blood flow. This helps ease symptoms of congestive heart failure, enhances circulation, and supports better oxygen delivery to the body’s tissues, allowing dogs to feel more active and comfortable.
