Mechanism of Action

Lisinopril is an inhibitor of angiotensin-I converting enzyme (ACE inhibitor). The beneficial effects of ACE inhibitors appear to result primarily from the suppression of the plasma renin-angiotensin-aldosterone system. Renin is synthesized by the kidneys and released into the circulation where it converts angiotensinogen to angiotensin-I. Angiotensin-I is then converted by angiotensin converting enzyme to angiotensin-II. Angiotensin-II is a potent vasoconstrictor responsible for arterial vasoconstriction and increased blood pressure, as well as for stimulation of the adrenal gland to secrete aldosterone. Inhibition of ACE results in decreased plasma angiotensin-II, which leads to decreased vasopressor activity and to reduced aldosterone secretion. The latter decrease may result in an increase in serum potassium concentration. Lisinopril is used in the treatment of hypertension and heart failure. It also improves your survival if you are taking it after a recent heart attack of for heart failure. It works by widening your blood vessels and making it easier for your heart to pump blood around your body. It can also be used for diabetic kidney disease, to slow down the disease.

Lisinopril comes as tablet.

Route of Administration

Lisinopril is administered orally in a single daily dose. The absorption of Lisinopril tablet is not affected by food.

Dosage

Hypertension

Adult: initially 10 mg once daily; maintenance 20 mg once daily; maximum 80 mg/day.

Heart failure

Adult: initially 2.5 mg once daily, increased in steps of up to 10 mg at least every 2 weeks; maximum 35 mg per day if tolerated.

Diabetic kidney disease 10 mg to 20 mg once daily

The antihypertensive effects of lisinopril are seen within 1 to 2 hours of a single oral dose and the maximum effect occurs after about 6 hours, although the full effect may not develop for several weeks during chronic dosing.

The haemodynamic action lasts for about 24 hours after once-daily dosing.
