Clinical trial of captopril (Aceten) in Indian patients with essential hypertension.
ACE inhibitors are not available in India. Response to captopril in comparison with M-dopa was therefore seen in Indian hypertensive patients. A double blind randomized non-crossover study was carried out on 39 adult patients of either sex suffering from essential hypertension. Twenty-five patients included were resistant to earlier drug therapy. The remaining 14 were freshly detected hypertensive patients. Patients received either 150 mg/day captopril (Aceten) or 750 mg/day M-dopa in 3 equally divided doses every day for 30 days. The mean systolic and diastolic blood pressure in captopril (Aceten) group before starting drug therapy was 171 +/- 4.11 (mean +/- SE) and 111 +/- 0.22, respectively. At the end of therapy the systolic blood pressure was 132 +/- 1.86 and diastolic blood pressure was 84 +/- 1.36 mm of mercury. This fall in the blood pressure within the group was statistically highly significant (p less than 0.001). Similarly patients on M-dopa produced statistically highly significant fall in blood pressure (p less than 0.001) at the end of 4 weeks therapy. Initial systolic and diastolic blood pressure in both groups were comparable and, at the end of 2 and 4 weeks therapy, patients on captopril (Aceten) showed greater fall in both systolic (p less than 0.001) and diastolic (p less than 0.005) blood pressure than patients on M-dopa. None of the patients in the trial demonstrated clinically significant changes in the biochemical parameters. Six of nineteen patients on methyl dopa had side effects which are well known to this drug. None in the captopril showed any side effect.(ABSTRACT TRUNCATED AT 250 WORDS)
