Angiotensin-converting enzyme (ACE) inhibition. Therapeutic option for diabetic hypertensive patients.
When choosing antihypertensive agents for the treatment of diabetic patients with hypertension, it is necessary to consider the individual characteristics of these patients. In this respect, angiotensin-converting enzyme (ACE) inhibitors constitute an attractive option for diabetic patients. The effects of enalapril alone for 16 weeks in 23 non-insulin-dependent diabetic (NIDD) patients and in 10 non-diabetic patients with mild to moderate essential hypertension (EH) [diastolic blood pressure greater than 95 mm Hg and less than 115 mm Hg] were evaluated. Similar reductions in both systolic and diastolic blood pressure were observed in 17 NIDD patients (from 155 +/- 18/100 +/-11 mm Hg to 128 +/- 12/82 +/- 8 mm Hg, respectively) and in 6 EH patients (from 155 +/- 21/100 +/- 6 mm Hg to 125 +/- 20/84 +/- 8 mm Hg, respectively) who achieved and maintained blood pressure control (diastolic blood pressure less than 90 mm Hg) for 16 weeks. In 4 NIDD and 4 EH patients blood pressure was not controlled. Two NIDD patients discontinued the medication, one because of symptomatic postural hypotension and the other, who had a plasma creatinine level of 1.8 mg/dl, because of hyperkalaemia (K = 6.1 mEq/L). In the responders, enalapril did not alter glucose tolerance, plasma or urinary excretion of creatinine, potassium, sodium and aldosterone. Plasma renin activity increased in the NIDD group only. In 11 patients (6 NIDD and 5 EH), the elevated protein or albumin excretions decreased. It is concluded that enalapril is a good therapeutic option for NIDD patients with hypertension.
