Add-on Pentoxifylline to Losartan Versus Increasing Dose of Losartan on NT-PRO BNP in Type 2 Diabetics With Nephropathy

Comparative Effects of add-on Pentoxifylline to Losartan Versus Increasing Dose of Losartan on Serum NT-PRO BNP and Proteinuria in Type 2 Diabetics With Nephropathy

This study was designed to assess the efficacy of adding pentoxifylline to losartan in comparison with increasing dose of losartan in type 2 diabetes patients with nephropathy. also the effect of pentoxifylline on N terminal brain natriuretic peptide (NT-pro BNP) and C-reactive protein

Addition of pentoxifylline to losartan provides antiproteinuric effects in type 2 diabetes patients with nephropathy that might relate to its effect on N terminal brain natriuretic peptide (NT-pro BNP) and C-reactive protein.

Pentoxifylline is a phosphodiestrase inhibitor with anti-inflammatory effects that was used in type 2 diabetes patients with nephropathy for treatment of diabetes complications.

NT-Pro BNP, which is released from the heart due to wall stress and pressures, is known as a diagnostic and prognostic marker for heart failure and cardiovascular mortality in type 2 diabetes.
