Abstract
The angiotensin-converting enzyme (ACE) inhibitor trandolapril, a non-sulfhydryl prodrug which is hydrolysed into trandolaprilat, was studied in 322 hypertensives of African–American descent using a double-blind, randomised, placebo-controlled, parallel study design. Following 6 weeks of double-blind treatment with placebo or 0.25 to 16 mg/day trandolapril, an analysis of drug effect on trough blood pressure (BP) stratified by age, gender, weight, pre-treatment plasma renin activity, and trandolaprilat concentration was performed. Two mg was the lowest effective trandolapril dose, whereas doses above 4 mg did not significantly reduce trough BP. Reduction in BP did not correlate with trough plasma trandolaprilat concentration. Pre-treatment plasma renin activity was not a reliable indicator of antihypertensive response, as similar reductions in BP occurred even in patients with the lowest renin levels. There were no observable differences based on age, gender or measurements of the renin-angiotensin- aldosterone axis. In conclusion, neither age, gender or plasma renin activity influenced anti-hypertensive response to angiotensin-converting enzyme inhibition in African–Americans
