Kidney disease

According to a 2006 article in the New England Journal of Medicine, patients with advanced renal insufficiency taking benazepril showed "substantial" kidney benefits. A long term study of patients' kidney disease revealed that patients who took benazepril had better kidney function and a slower progression of kidney disease. Kidney function was much better in the group of patients taking the drug than their peers who took a placebo drug. This is notable because this category of pharmaceuticals have long been thought to cause further kidney damage or increase the rate of progression for kidney disease.

ACE inhibitors can pose a potential threat to kidneys as well. The key question was whether damaged kidneys would worsen if patients took ACE inhibitors. In a nutshell, concerns centered on blood levels of potassium and creatinine, waste products that are excreted by the kidneys. Testing creatinine levels in the blood is used as a way to monitor kidney function (. . . ) kidney problems worsened more slowly in those taking Lotensin. Overall, there were no major differences in side effects between patients taking Lotensin or the placebo.
