Hyperkalemia in Outpatients Using Angiotensin-Converting Enzyme Inhibitors

Abstract
ANGIOTENSIN-converting enzyme (ACE) inhibitors are widely used in the treatment of several common clinical conditions. It has been estimated that ACE inhibitors accounted for 24% of the antihypertensive agents prescribed in 1993.1 In other conditions, such as congestive heart failure2 and diabetic nephropathy,3 they have been shown to improve important clinical outcomes.
