Overview
The investigators designed a randomized parallel controlled clinical study, selected 98 cases of diabetic nephropathy patients with urinary protein > 1g, randomly assigned into the Kunxian capsule + irbesartan group or irbesartan group, 48 weeks of treatment and follow-up, reduced levels of urinary protein and effective relief time, remission rate as the main end point, estimated glomerular filtration rate (eGFR) drop rate slope for secondary end points, safety events were also collected. To evaluate the efficacy and safety of Kunxian capsule combined with irbesartan in treatment of diabetic nephropathy compared with irbesartan alone.
