Controlled multicentre comparison of captopril versus lisinopril in the treatment of mild-to-moderate arterial hypertension.
The antihypertensive efficacy and safety of lisinopril (L), a novel ACE inhibitor, were compared to those of captopril (C), the familiar drug of the same class, in a multicentre controlled trial. The study included 91 mild-to-moderate, middle-aged hypertensives of both genders, 46 of which were randomized to C and 45 to L. After a two-week placebo period the examinees were receiving either L o.d. in increasing dosage of 10, 20, or 40 mg per day (amount necessary to achieve normotension), or C b.i.d. in a corresponding daily dose of 25, 50, or 100 mg. During the eight-week formal part of the trial, L decreased the systolic blood pressure from the initial values by an average of 14.9%, and the diastolic pressure by some 15.2%. The same parameters were lowered on C by 11.2%, and 11.7%, respectively. The mean arterial pressure from an initial average of 125.5 mmHg was lowered to 110.9 mmHg on C (11.6% reduction, p < 0.01), and from 125.3 mmHg to 108.2 mmHg on L (13.6% reduction, p < 0.01). Although the L effects were more pronounced, the observed between-group differences did not reach the level of statistical significance, except for the achievement of normotension, which disclosed the superiority of L (p < 0.05). The tolerability of both drugs was good and only one examinee had to be excluded because of side-effects (proteinuria). It is concluded that both ACEIs under study showed comparable efficacy and safety, L being marginally more potent and longer acting.
