What Experts Say

Lisinopril belongs to the ACE inhibitor class and works by blocking the enzyme that converts angiotensin I into angiotensin II. This reduces vascular resistance, lowers blood pressure, and decreases aldosterone secretion, which helps the body eliminate excess sodium and fluid more efficiently.

In heart failure, this same mechanism eases the workload on the heart by reducing both preload and afterload. Multiple clinical trials have shown that ACE inhibitors like lisinopril improve survival and lower hospitalization rates when combined with standard heart failure therapy such as beta blockers and diuretics.

The 5 mg strength is commonly used as a starting dose for elderly patients, those with reduced kidney function, or people beginning ACE inhibitor therapy for the first time. Doctors usually titrate the dose upward gradually while monitoring blood pressure, kidney function, and potassium levels closely during the first few weeks of treatment.

• Kidney Function: May worsen kidney function in patients with existing kidney disease or dehydration
• High Potassium: Can raise blood potassium levels, which may affect heart rhythm
• Angioedema: Rare but serious swelling of the face, lips, tongue, or throat requires immediate medical attention
