Data from 6 controlled clinical trials of oxprenolol carried out in the United States were reviewed to determine the efficacy and tolerability of oxprenolol in patients aged greater than or equal to 55 years. All study designs but 1 called for dosage to be increased to a maximum of 480 mg/day. In a 10-week trial of oxprenolol versus placebo given twice daily, oxprenolol reduced diastolic pressure by 8 mm Hg, while placebo reduced it by 3 mm Hg. A comparison of once-daily with twice-daily dosing showed similar results for both groups: -12/-6 mm Hg for once-daily and -9/-8 mm Hg for twice-daily. There were 2 short-term studies comparing oxprenolol and placebo, both given in addition to hydrochlorothiazide. In the first, the change in blood pressure with oxprenolol was -18/-14 mm Hg and with placebo was +6/-3 mm Hg; only 3 of 14 patients receiving oxprenolol received a maximal dosage. In the follow-up study, most of the dosages were titrated to maximum; reductions were -9/-9 mm Hg with oxprenolol treatment and 0/-12 mm Hg with placebo. Two long-term studies compared oxprenolol and propranolol, also as combination therapy with hydrochlorothiazide. In the 14-week study, the reduction in blood pressure was slightly better with oxprenolol: -15/-15 versus -12/-11 mm Hg. In the 27-week study, almost half of the patients in the oxprenolol group received the maximal dosage. Blood pressure was reduced 2 or 3 mm Hg less with oxprenolol than with propranolol. Oxprenolol was well tolerated in the elderly; it produced a low incidence of typical beta-blocker side effects even when given in a once-daily regimen.
