To date, dual and triple blockade of the RAAS has been evaluated. The aim of this study was comparing three (ACEI+ARB+ ß blocker) and two (ACEI+ARB) directional inhibitions of RAAS in treatment of diabetic nephropathy.   Materials & Methods : In an experimental interventional study, 103 diabetic patients without ESRD were recruited in Tabriz Sina Hospital during a one-year period. The patients were randomized in two groups: group A received triple blockade of RAAS with ACEI+ARB+ß blocker, and group B received dual blockade with ACEI+ARB (and placebo). Basal and post treatment parameters including blood pressure, urine albumin, serum BUN, Cr, Na, K , HbA1C, and GFR were compared.   Results : Both study groups were matched for age, sex and duration of diabetes mellitus. Decrease of blood pressure, albuminuria, BUN, and Cr was more significant in group A compared with group B. The GFR rose more significantly in group A compared with group B. The frequency of hyperkalemia was significantly higher in group A.   Conclusion : Triple blockade of RAAS is more efficient that dual blockade in prevention of diabetic nephropathy however, meticulous selection of patients should be considered because of higher risk of hyperkalemia.     Address : Nephrology Department, Tabriz University of Medical Sciences, Tabriz, Iran   Tel : (+98)9143115927     Email : hamidnoshad1@yahoo.com     Source: Urmia Med J 2010: 21(3): 278 ISSN: 1027-3727 LA eng UL http://umj.umsu.ac.ir/article-1-735-en.html M3 ER -
