A trial to study the efficacy, safety and tolerability of nitrendipine and enalapril in the treatment of diabetic hypertensive patients with microalbuminuria (MA) was performed to compare the effects of both drugs in the prevention of the renal impairment. Twenty-eight valid patients [13 with nitrendipine (N) and 15 with enalapril (E) with NIDDM, hypertension (diastolic blood pressure between 90 to 114 mm Hg) and MA (urinary albumin between 30 to 300 mg/24 hr) were recruited in a double blind, randomized trial. Following a placebo run-in period of two to four weeks, all eligible patients were randomly allocated to either N or E treatment. Treatment lasted six months, with two different visits at three and six months in which blood pressure (BP), heart rate (HR), renal function and MA were measured. No statistically significant differences on BP and metabolic parameters were found between both treatment groups. The geometric mean of final glomerular filtration rate (GFR) in the N group was 34.5% higher than in the E group, while the reduction on MA was most important in the E group. Eleven patients reported adverse events (AEs) and there were four dropouts, three of them due to AEs. We conclude that both treatments are a good choice for treating diabetic hypertensive patients with early altered renal function, as they reduce BP without altering metabolic parameters, increase GFR and reduce MA with a low frequency of AEs.
