Temocapril is primarily used in the treatment of hypertension (high blood pressure) and heart failure. It works by inhibiting the angiotensin-converting enzyme (ACE), which helps relax blood vessels, reducing the workload on the heart and improving blood flow. This medication is often prescribed to manage chronic conditions, preventing complications such as strokes, heart attacks, and kidney problems. It is typically administered orally and is part of a comprehensive treatment plan that may include lifestyle changes and other medications. Patients are usually monitored for side effects like dizziness or kidney function changes during treatment.
