Lisinopril. A preliminary review of its pharmacodynamic and pharmacokinetic properties, and therapeutic use in hypertension and congestive heart failure.
Lisinopril is an orally active angiotensin-converting enzyme (ACE) inhibitor which at dosages of 20 to 80 mg once daily is effective in lowering blood pressure in all grades of essential hypertension. It is at least as effective as usual therapeutic dosages of hydrochlorothiazide, atenolol, metoprolol and nifedipine while direct comparisons with other ACE inhibitors have not been reported. Many patients achieve an adequate blood pressure reduction with lisinopril alone, and in those who do not, most will with the addition of hydrochlorothiazide; lisinopril also attenuates hypokalaemia induced by thiazide diuretics. In patients with congestive heart failure resistant to conventional therapy, lisinopril 2.5 to 20 mg once daily improved indices of cardiac function and appeared to produce greater benefit than captopril in one controlled study. Lisinopril is well tolerated, with few serious adverse effects being reported. Thus, lisinopril is a suitable treatment for essential hypertension and shows promise in the treatment of congestive heart failure. If additional studies confirm these preliminary findings, then lisinopril will have a similar profile of indications to other ACE inhibitors, and like some other drugs in this class it offers the convenience of once daily administration.
