Used primarily to treat high blood pressure (hypertension), Lisinopril Dihydrate helps reduce the risk of heart attack, stroke, and kidney problems. It is also prescribed for patients with heart failure or those recovering from a heart attack to improve survival and prevent further cardiac damage. As an ACE inhibitor, it works by relaxing blood vessels, allowing blood to flow more easily. This medication is often favored for its once-daily dosing and effectiveness in both lowering blood pressure and protecting kidney function, especially in diabetic patients.
