  • Title: Ketanserin in mild to moderate hypertension in the elderly: a double-blind study versus methyldopa.
    Author: Cattin L, Da Col PG.
    Journal: Clin Ther; 1989; 11(3):363-72. PubMed ID: 2663164.
    Abstract:
    In a double-blind study of 30 elderly patients with mild to moderate essential hypertension, the antihypertensive effects of ketanserin and methyldopa were compared. The patients were randomly assigned to receive 20 mg of ketanserin or 250 mg of methyldopa twice daily for two weeks; the dose was then doubled for the rest of the three-month period. Two of the ketanserin group dropped out of treatment, one because of psychic depression, the other because of epigastric pain. After three months of therapy with ketanserin, systolic blood pressure decreased in a dose-dependent manner from 190 +/- 20 to 175 +/- 20 mmHg (P less than 0.05) and diastolic blood pressure from 106 +/- 8 to 91 +/- 9 mmHg (P less than 0.001). Blood pressure was reduced to 160/90 mmHg or less in eight of the 13 ketanserin patients and in five of the 15 methyldopa patients. In both groups heart rate and body weight remained constant. No orthostatic hypotension or hypertensive rebound after ketanserin withdrawal was recorded. It is concluded that 40 mg of ketanserin twice daily can control hypertension in the elderly.
