Lisinopril: a new angiotensin-converting enzyme inhibitor.

Abstract

Lisinopril is a synthetic, nonsulfhydryl, angiotensin-converting enzyme inhibitor. Its bioavailability is approximately 25% and is not affected by food. Hepatic metabolism is not required for pharmacologic effect, which occurs 1 hour after administration. Peak serum concentration and effect are delayed, occurring 6-8 hours after a single dose and lasting for at least 24 hours. The drug is eliminated primarily by the kidneys. The elimination half-life is 12.6 hours and is prolonged in renal impairment. Lisinopril 10-80 mg once a day is effective in lowering blood pressure in all grades of essential and renovascular hypertension. It is as effective as hydrochlorothiazide, atenolol, metoprolol, and nifedipine. Combining lisinopril with hydrochlorothiazide produces a greater degree of blood pressure reduction. Patients with congestive heart failure have demonstrated immediate and prolonged beneficial hemodynamic effects and increased exercise tolerance. Lisinopril is well tolerated. Clinically significant drug interactions have not been reported, but caution should be used when lisinopril is administered with diuretics, nifedipine, or agents that may increase concentrations of potassium. The usual initial oral dosage of lisinopril is 10 mg once a day (range 20-40 mg/day). Lower dosages may be necessary in patients with renal impairment or congestive heart failure, elderly persons, and those receiving diuretics.
