Antihypertensive effectiveness of oxprenolol administered twice daily.

Oxprenolol, a beta-blocker, is an effective antihypertensive when administered 3 or 4 times daily. We evaluated the antihypertensive effect of oxprenololgiven twice daily (bid). The subjects were 15 ambulatory men whose standing diastolic blood pressure (BP) was at least 100 mm Hg after 3 wk of treatment with hydrochlorothiazide and oxprenolol placebo. Oxprenolol 40 mg twice daily was then substituted for the placebo. On subsequent weekly vists oxprenolol was titrated to 80 and 160 mg bid if the standing diastolic BP was greater than 90 mm Hg. BLood pressures on the last visit on placebo were compared to those on the last visit on oxprenolol. Standing BP declined from 145 +/- 4/108 +/- 1 to 130 +/- 4/98 +/- 4 on a mean dose of 256 mg of oxprenolol (p less than 0.001 syst.; p less than 0.01 diast.). Recumbent BP fell from 146 +/- 4/107 +/- 1 to 138 +/- 5/93 +/- 2 (p less than 0.06 syst.; p less than 0.01 diast.). During the final week, 13 of the 15 patients were admitted to the hospital for 24-hr monitoring of BP. The 24-hr BP readings showed a mean coefficient of variation of 6.6% recumbent and 7.2% standing. we conclude that bid oxprenolol will maintain 24 hr BP control in most patients.

Antihypertensive effects of oxprenolol and propranolol.

The antihypertensive effects of the beta blockers oxprenolol and propranolol were compared in a randomized double-blind study of patients with standing diastolic pressures (SDP) exceeding 99 mm Hg when receiving hydrochlorothiazide alone. After 3 wk of hydrochlorthiazide with placebo, the latter was replaced with oxprenolol (n= 12) or propranolol (n = 14), 20 mg three times daily. Beta blocker was increased subsequently to 40 and 80 mg three times daily if SDP exceeded 89 mm Hg. Nine oxprenolol and 7 propranolol subjects were hospitalized for 24-hr monitoring. With oxprenolol, standing pressure declined from 135 +/- 2 (SE)/104 +/- 1 MM Hg to 128 +/- 3/90 +/- 2. SDP declined to under 91 mm Hg in 7 of 12 subjects, and to from 91 to 95 in 3 subjects. With propranolol, findings were 138 +/- 3/106 +/- 2 to 123 +/- 3/89 +/- 3; in 7 of 12 to less than 91 mm Hg and from 91 to 95 in 4 subjects. Decrements in supine and SDP were slightly (4 mm Hg) greater for propranolol than for oxprenolol. Both drugs gave similar 24-hr blood pressure control. We conclude that oxprenolol and propranolol used to supplement hydrochlorothiazide provide comparable reductions in blood pressure and smooth control over a 24-hr period in most patients with hypertension.
