Candesartan shows beneficial end-organ effects in the kidney. Some of these appear to be related not to the reduction in systemic blood pressure induced by candesartan, but to its blockage of intrarenal angiotensin II type I (AT1) receptors. Initial studies have shown that renal vascular resistance was reduced in patients with hypertension receiving candesartan, and urinary albumin excretion was reduced in patients with type 2 diabetes mellitus and concomitant microalbuminuria or proteinuria. These findings, together with the results of recently published large randomized studies involving diabetic patients with hypertension treated with other angiotensin II receptor blockers, indicate that this class of drugs is beneficial in preventing the development or progression of diabetic nephropathy. This review summarizes the large body of findings related to these renoprotective effects and reported during experimental and clinical research on candesartan for the treatment of diabetic nephropathy.
