In the patients with chronic kidney disease associated with hypertension, the effects of combination of losartan and low dose of hydrochlorochiazide, combination of losartan and enalapril, and combination of kosartan and amlodipine on blood pressure and urinary excretion of protein or albumin are compared. In addition, achievement rate of goal blood pressure, tolerability, and the effects on metabolism are observed.
Efficacy
Exploratory
Blood pressure changes at 4 months after the start of combination therapy
Changes in systolic blood pressure at 4 months after the start of combination therapy
Rates of systolic blood pressure change and achievement of goal systolic blood pressure at 4 months after the start of combination therapy
Rates of changes in urinary excretion of protein or albumin at 4 months after the start of combination therapy
Rates and values of systolic blood pressure at 12 months after the start of combination therapy
Rates of changes in urinary excretion of protein or albumin at 12 months after the start of combination therapy
Changes in eGFR values at 12 months after the start of combination therapy
Rates of achievement of goal blood pressure 12 months after the start of combination therapy
Changes in HOMA-R
