The effects on diabetic control of the relative cardioselective beta-blocker metoprolol and the non-selective drug propranolol were compared in 20 hypertensive diabetic patients receiving diet alone or diet and oral hypoglycaemic agents. Each drug was given for one month in a double-blind, cross-over study. Fasting, noon, and mid-afternoon blood sugar concentrations rose by 1.0-1.5 mmol/l (18-27 mg/100 ml). The rise with propranolol was not significantly greater than with metoprolol. In a few patients the rise was clinically important. The small overall change observed in diabetic control should not deter the use of beta-blockers in non-insulin-dependent diabetics, provided control is carefully monitored at the onset of treatment.
在20名仅接受饮食治疗或饮食及口服降糖药治疗的高血压糖尿病患者中,比较了相对心脏选择性β受体阻滞剂美托洛尔和非选择性药物普萘洛尔对糖尿病控制的影响。在一项双盲交叉研究中,每种药物给药一个月。空腹、中午和下午血糖浓度升高1.0 - 1.5 mmol/l(18 - 27 mg/100 ml)。普萘洛尔引起的升高并不显著高于美托洛尔。在少数患者中,这种升高具有临床意义。在糖尿病控制方面观察到的总体变化较小,但只要在治疗开始时仔细监测控制情况,就不应妨碍在非胰岛素依赖型糖尿病患者中使用β受体阻滞剂。
