Zestril (Lisinopril) 5 mg is a lower-dose version of the ACE inhibitor Lisinopril, used to manage high blood pressure and heart failure. This medication helps relax blood vessels, improving blood flow and reducing the workload on the heart. It is often prescribed as part of a comprehensive treatment plan that may include lifestyle changes such as a healthy diet and regular exercise. Zestril 5 mg is suitable for patients who require a lower starting dose or have specific medical conditions that necessitate reduced dosage. Always consult your healthcare provider to determine the appropriate strength for your needs.
