How to Choose

Understanding ACE Inhibitors and Cardiac Medications for Dogs

ACE inhibitors represent a fundamental advancement in managing canine heart disease. By inhibiting the angiotensin-converting enzyme, these medications prevent the formation of angiotensin II, a hormone that constricts blood vessels and increases blood pressure. This pharmacological action reduces afterload on the heart, meaning the organ doesn't have to work as hard to pump blood throughout your dog's body. Veterinary cardiologists in the United Kingdom frequently prescribe these medications alongside other treatments such as diuretics for fluid management or pimobendan (Vetmedin) for additional inotropic support. Understanding how these medications complement each other helps dog owners appreciate their vet's treatment recommendations and recognise the importance of medication compliance.
