Therapeutic safety of perindopril in the treatment of mild hypertension with concomitant nephropathy.
Angiotensin-converting enzyme (ACE) inhibitors are well established antihypertensives. Their effect on kidney function, however, seems to depend on the pathophysiological mechanisms underlying the clinical symptoms. In one part of the Perindopril and Therapeutic Safety Study (PUTS) the effect of a 6-week treatment with placebo or 4 mg/d of perindopril (Coversum, CAS 82834-16-0) on kidney function and albuminuria was investigated in 56 hypertensives with concomitant nephropathy. The study was performed as multicenter, randomized, placebo-controlled, double-blind study. The results show that perindopril reduced blood pressure effectively. The responder rate determined as a fall in blood pressure at least about 10 mmHg in the perindopril group was 39% vs. 21% in the placebo group. All investigated parameters of kidney function like serum creatinine, creatinine clearance, urinary excretion of albumin and alpha 1-microglobulin remained unchanged during the study. In a subgroup of patients with isolated albuminuria ACE inhibition reduced significantly the urinary albumin excretion (perindopril: -292 +/- 205 mg/g creat. vs. placebo: +61 +/- 48 mg/g creat: p < 0.05). From this study it can be concluded that in hypertension with concomitant nephropathy, except renovascular hypertension and hypertension in renal transplant recipients, ACE inhibition by perindopril will not impair kidney function. In the early phase of nephropathy with isolated albuminuria and normal serum creatinine perindopril improves albuminuria and seems to be even of benefit for the kidney.
