[Multicenter comparative study of the effects of benazepril and captopril in mild and moderate systemic hypertension].
OBJECTIVE
To evaluate the efficacy and safety of benazepril versus captopril in patients with mild or moderate systemic arterial hypertension (SAH).


METHODS
A multicenter, double-blind, randomized trial analyzed 174 patients, mean age of 52 +/- 9 years, 68 (39%) men. After 2 weeks under placebo, 90 patients were treated, during 6 weeks, with 10 mg, once a day, of benazepril (BZ) and 50 mg, twice a day, of captopril (CPT). At week 3, 25 mg of hydrochlorothiazide (HCT) was added if diastolic blood pressure (DBP) was greater than 90 mmHg. Side effects were analyzed as a not related, unlikely, possible, probable and definitive regard to treatment.


RESULTS
Systolic (p < 0.001) and DBP (p < 0.0001) reductions were observed in both groups. Additional reduction was observed in both groups when 25 mg of HCT was added in patients with DBP > 90 mmHg at week 3. Heart rate was unchanged. The response to treatment was better at BZ group (74% versus 59% of good and excellent response; p = 0.037). Side effects classified as probable or definitive in relation to the treatment occur in 3 (3%) and 10 (11%), respectively at BZ an CPT groups. Laboratorial changes were not observed during treatment.


CONCLUSIONS
BZ (10 mg) was superior to CPT (50 mg) in patients with discrete and moderate SAH.
