Cite This Study

Lee et al. (2011) conducted an RCT in Chronic kidney disease with non-nephrotic-range proteinuria (n=32). Losartan vs. Control was evaluated on Percentage change in proteinuria (43% reduction, p=<0.0001). Losartan significantly reduced urinary protein excretion by 43% (p<0.0001) and preserved renal function in non-diabetic patients with chronic kidney disease.
