Objective Guidelines recommend lower threshold and goal blood pressure (BP) for patients with proteinuria. BP reduction could be accompanied by a different fall in proteinuria depending of the antihypertensive drug. The objective was to compare proteinuria reduction when BP is lowered to the same level with different drugs. Design Prospective, randomized, double-blind, controlled trial. Setting 12 Spanish centres. Patients A total of 119 patients with primary renal disease, blood pressure > 130/85 mmHg, proteinuria > 1 g/day, and creatinine clearance ⩾ 50 ml/min. Intervention After a 4-week run-in placebo period, patients were randomized to: atenolol 50 mg/day; trandolapril 2 mg/day; verapamil 240 mg/day or verapamil 180 + trandolapril 2 mg/day combination; forced double-dose titration was carried out at the 4th week. Treatment duration was 6 months. Outcome measures Changes in BP, 24 h proteinuria, serum albumin and calcium. Results BP was significantly reduced with the four treatments [SBP/DBP (mmHg]: atenolol 12.2/9.9; trandolapril 12.9/9.3; verapamil 8.2/7.9 and verapamil + trandolapril 13.6/11.3) without differences between them. A significant fall in proteinuria was seen in the trandolapril, 40.2% [95% confidence interval (CI) 24.3–56.2%], and verapamil + trandolapril groups, 48.5% (95% CI, 31.7–64.3%) accompanied with increases in serum albumin (trandolapril: from 3.86 ± 0.64 to 4.03 ± 0.67 g/dl; verapamil + trandolapril: from 4.15 ± 0.58 to 4.40 ± 0.51 g/dl). Conclusions In patients with proteinuric primary renal disease, adequate dose titration of antihypertensive drugs may provide a substantial BP reduction. Only angiotensin-converting enzyme inhibitor (trandolapril) treatment, alone or better combined with verapamil, reduces proteinuria and increases serum albumin.
