Alacepril is primarily used in veterinary medicine as an angiotensin-converting enzyme (ACE) inhibitor. It is commonly prescribed to manage heart failure and hypertension in dogs and cats. By inhibiting ACE, it helps relax blood vessels, reduce blood pressure, and decrease the workload on the heart, improving overall cardiac function. It is often administered orally and is valued for its efficacy in improving the quality of life in pets with cardiovascular conditions. Regular monitoring by a veterinarian is essential to ensure proper dosage and to manage potential side effects.
