Long-Term Renoprotection of Optimal Antiproteinuric Doses of Benazepril and Losartan in Chronic Renal Insufficiency

• Status: Terminated
• Trial end date: 2006-05-01
• Target enrollment: 0
• Participant gender: All

Summary

The primary goal of the trial was to evaluate whether the optimal antiproteinuric doses of benazepril (an ACE inhibitor) or losartan (an ARB), as compared with their conventional doses, can safely improve the long-term renal outcome in nondiabetic patients with proteinuria and chronic renal insufficiency. The second aim was to compare the long-term renal protection between benazepril and losartan at similar clinical setting.

• Phase: N/A
