Dose Response Studies of Bevantolol in Hypertensive Patients

This multicenter study, conducted to determine the antihypertensive efficacy of bevantolol at different fixed doses compared with placebo was carried out at four separate institutions using a common protocol. One hundred thirty-nine patients with mild to moderate essential hypertension were enrolled. At doses of 200 to 400 mg/day bevantolol was clearly effective in lowering diastolic blood pressure and in maintaining this effect over the eight weeks of this double-blind study. Twice a day dosing is indicated since efficacy was evident 12 hours post- dosing. Bevantolol was well tolerated.
