Enalapril is a prescription medication that may be used to help manage certain heart conditions in pets, such as heart failure, dilated cardiomyopathy, or high blood pressure. It may also be considered in some cases involving chronic kidney disease. Enalapril is thought to support cardiovascular function by helping to lower blood pressure and reduce strain on the heart. Use and dosage should always be determined by a veterinarian based on the individual needs of the pet.
