title: [Significance of inhibitors of conversion enzymes in elderly subjects. The example of perindopril].
abstract: The effectiveness and safety of perindopril in elderly hypertensive patients has clearly been demonstrated. In a randomized, double-blind drug versus placebo study involving 34 such patients of mean age 84 years, we observed a 10 p. 100 fall in systolic arterial pressure (p less than 0.01) and a 9 p. 100 fall in diastolic arterial pressure (p less than 0.01) in the perindopril group. The corresponding figures in the placebo group were 5 p. 100 and 4 p. 100 respectively, the difference between the two groups not being significant. The drug was well tolerated, both clinically and biochemically. However, a significant (p less than 0.01) increase in blood potassium level (albeit within normal limits) was observed in the treated group. An open trial conducted in 91 patients (mean age 79.1 years) followed up for 6 years confirmed the acceptability of the drug despite a transient decrease of creatinine clearance recorded in one patient. The effectiveness of perindopril, evaluated less unquestionably in this open trial, was excellent, the hypertension being controlled at the end of treatment in 92.5 p. 100 of the patients. In a trial performed on healthy volunteers, Reid found that perindopril had a greater effect of arterial pressure in elderly subjects, probably due in part to their high blood pressure and to an earlier and more prolonged inhibition of the angiotensin-converting enzyme (NS).(ABSTRACT TRUNCATED AT 250 WORDS)
