title: [Evaluation of the safety and efficacy of the lisinopril + hydrochlorothiazide and captopril + hydrochlorothiazide combinations in the treatment of essential arterial hypertension].
abstract: The aim of this study was to assess the efficacy and tolerability of the combinations of lisinopril (LIS) 20 mg + hydrochlorothiazide (HCTZ) 12.5 mg and captopril (CAP) 50 mg + HCTZ 25 mg in moderately hypertensive patients not adequately controlled by LIS or CAP alone. The study was multicentre (11 centres), open, random and carried out in parallel groups. After two weeks' placebo run in patients were randomly assigned to LIS 10-20 mg/o.d. or CAP 25-50 mg/b.i.d. treatment for 6 weeks. After this, patients with supine diastolic blood pressure (SDBP) greater than 90 mmHg were treated with the combinations LIS 20 mg + HCTZ 12.5 mg/o.d. or CAP 50 mg + HCTZ 25 mg/o.d. for 4 weeks; this dose was doubled if DBP was found to be greater than 90 mmHg after 2 weeks' combined therapy. A total of 175 patients were enrolled (92 females and 83 males) of which 153 completed the study. The LIS + HCTZ association caused a significant reduction of DBP in comparison to the other combined treatment (88.1 +/- 0.7 vs 90.3 +/- 0.7; p = 0.026). The statistical analysis of mean SBP values showed no significant difference between the two groups (144.0 +/- 1.3 vs 146.8 +/- 1.3; p = 0.15). At the end of the study 79.5% of patients treated with LIS + HCTZ presented normal results (DBP less than or equal to 90 mmHg), whereas the percentage of similar results in the comparison group was 72%. The percentage of "responder" patients to therapy (DBP reduced by 10 mmHg or more in relation to basal values) was 96.3% in the LIS + HCTZ group and 86.7% in the CAP + HCTZ group. In the CAP + HCTZ group 0.6% of patients reported adverse reactions, while only 0.3% were observed in the LIS + HCTZ group.
