Conditions

Hypertensive patients with albuminuria under the treatment of the inhibitor of the renin-angiotension system (RAS)

Interventions

Benidipine (4 to 8 mg/day) is added in patients with the treatment of the RAS inhibitor. If BP does not reach to lower than 130/80 mmHg, other antihypertensive drug than CCB, diuretic and RAS inhibit

Design outcomes

Primary

MeasureTime frame
Changes in urinary albumin/ creatinine(Cr) ratio in spot urine from pretreatment period (average of 2 measured value) to 12 months of treatment

Secondary

MeasureTime frame
1. Urinary albumin/Cr ratio in fspot urine: Percent changes from pretreatment period to each period of treatment, etc. 2. Estimated glomerular filtration rate (eGFR) calculated using the modified MDRD formula in the Japanese Society of Nephrology: eGFR (ml/min/1.73 m2) = 194 x age -0.287 x serum Cr - 1.094 (multiply by 0.739 in female) 3. Urinary liver-type free fatty acid-binding protein (L-FABP) 4. Serum Cr 5. Blood urea nitrogen (BUN) 6. Office blood pressure (BP) 7. Pulse rate 8. Renal events: Start of dialysis, renal transplantation 9. Cerebro-cardio-vascular events: Cerebro-cardio-vascular death (fatal myocardial infarction, fatal heart failure, sudden death, fatal stroke, other cardiovascular death) and hospitalization due to cerebro-cardio-vascular disease (nonfatal myocardial infarction, angina, heart failure, cerebral bleeding, cerebral infarction, transient cerebral ischemic attack)
