title: [Greater reduction of urinary albumin excretion in hypertensive patients with perindopril than nifedipine].
abstract: OBJECTIVE
  To examine the effect of perindopril and nifedipine on renal function in patients with essential hypertension (EH).
  
  
  METHODS
  52 cases with EH were divided randomly into two groups: perindopril group (4mg qd, n = 26); nifedipine group (10 mg tid, n = 26). Treatment period lasted for 24 weeks. Parameters of renal function were measured before and after treatment.
  
  
  RESULTS
  (1) After treatment, the arterial pressure decreased in a similar way in the two groups, urinary albumin excretion was significantly less after treatment in the perindopril group [urinary albumin excretion/24 h (mg/24 h): 66.7 +/- 25.9 vs 104.5 +/- 41.8, P < 0.01; urine protein/24h (g/L): 0.17 +/- 0.039 vs 0.24 +/- 0.064, P < 0.01], GFR (ml/min) was higher in the perindopril group after treatment (125.5 +/- 15.2 vs 112.2 +/- 13.2, P < 0.05). No significant changes were observed with nifedipine (P < 0.05). (2) No significant correlation between the decrement of urinary albumin excretion and of SBP, DBP was found in both groups (P > 0.05).
  
  
  CONCLUSIONS
  It is shown that perindopril, but not nifedipine, is able to reduce urinary excretion of albumin in patients with essential hypertension independently of its effective antihypertensive property. It is probable that the positive effect of perindopril on microalbuminuria is attributable to modification in intrarenal hemodynamics or to change in glomerular permeability.
