title: Angiotensin-converting enzyme inhibitors in the elderly.
abstract: Although early studies suggested little role for angiotensin-converting enzyme (ACE) inhibitors in older hypertensive patients, more careful evaluation has confirmed their efficacy and good tolerability. Although the elderly tend to have low plasma renin levels, the fall in blood pressure after ACE inhibitors is at least as great (and in several studies greater) than in younger age groups. Because several ACE inhibitors, including captopril and enalaprilat, are eliminated by the kidneys, there are predictable age-related effects on pharmacokinetics. Reduced renal clearance will contribute, at least in part, to the enhanced intensity and duration of action seen in elderly patients. However, not all the effects of age on the kinetics and dynamics of ACE inhibitors are predictable. Studies with perindopril and benazepril in the elderly confirm the efficacy of this group of drugs but highlight other pharmacokinetic differences. ACE inhibitors are effective in reducing blood pressure and can be considered for wider use in elderly hypertensives.
