Step-down therapy for hypertension. Results in a community-based program.

Overview

The study reported here involved a systematic attempt to withdraw medication from participants in a community-based hypertension treatment program. Sixty-six of 88 patients with well-controlled mild or moderate disease had medication withdrawn after at least six months of treatment; nonpharmacologic intervention was not employed. After one year, 44 (66.6%) remained normotensive and drug free; after two years, 33 (50.0%). Of the 29 patients still available for three-year follow-up, 15 (51.7%) were still normotensive and drug free. Withdrawal of medication was associated with correction of hypokalemia and reversal of impaired glucose tolerance. Thus, nearly one fourth of these patients, who were believed to be reasonably representative of those with mild or moderate hypertension, could discontinue drug therapy and remain normotensive for at least one year. Substantial medical and economic benefits are to be realized from wide replication of this experience.
