Lm. Molyneaux et al., INDAPAMIDE IS AS EFFECTIVE AS CAPTOPRIL IN THE CONTROL OF MICROALBUMINURIA IN DIABETES, Journal of cardiovascular pharmacology, 27(3), 1996, pp. 424-427
Microalbuminuria is a predictor of overt diabetic nephropathy and macr
ovascular disease. Thirty-one diabetic patients with persistent urinar
y albumin excretion rate (AER) of 20-200 mu g min(-1) were randomised
to receive indapamide 2.5 mg or captopril 37.5 mg daily for 12 weeks.
After a 4-week washout, patients received the alternate agent for 12 w
eeks. Resting blood pressure (BP), AER, cholesterol, triglycerides, an
d HbA(1c) were measured at baseline, after 6 and 12 weeks of each trea
tment, and after a 4-week washout period following each treatment arm.
Results from patients who completed at least one treatment arm were a
nalysed by repeated measures analysis of variance (ANOVA). AER (median
value and interquartile range) decreased significantly from baseline
after treatment with indapamide and captopril [60(27-106) vs. 40(14-11
2) and 33(17-100); p < 0.005], but there was no difference between the
effects of the two agents. Mean systolic BP (SEP) was also significan
tly reduced with treatment, and no difference was noted between the ef
fects of the two agents. No correlation between changes in AER and SEP
was noted with either agent. Diastolic blood pressure (DBP), choleste
rol, triglycerides, and HbA(1c) did not change during the study. These
results suggest that indapamide is an effective alternative to angiot
ensin-converting enzyme (ACE) inhibitors in the treatment of diabetic
patients with microalbuminuria.
