Assessment of the Effect of Captopril Versus Combination of Captopril and Pentoxifylline on Reducing Proteinuria in Type 2 Diabetic Nephropathy
April 21, 2008 updated by: Shiraz University of Medical Sciences
Phase 2 Trial of Effect of Combine Pentoxifylline and Captopril on Proteinuria in Diabetic Nephropathy
Diabetic nephropathy is the most common cause of ESRD and has a great impact on mortality and morbidity of diabetic patients.
Despite renoprotective effect of ACE inhibitors in diabetic patients they can not hinder the progression of renal disease completely.
Pentoxifylline as a TNFa blocker may hinder progression of diabetic nephropathy in combination of captopril.

Detailed Description
Diabetic nephropathy is the most common cause of ESRD and has a great impact on mortality and morbidity of diabetic patients.
Despite renoprotective effect of ACE inhibitors in diabetic patients they can not hinder the progression of renal disease completely.
TNFa is a cytokine that is a target for medical therapy in diabetic nephropathy.
In this study the effect of captopril on overt diabetic nephropathy compared to effect of combination of captopril and an antiTNFa drug ( pentoxifylline).
