Abstract

1 The effect of single oral doses of six beta-receptor antagonists on exercise-induced changes in double product (systolic blood pressure x heart rate) were studied in 25 human volunteers. 2 Three doses of propranolol, nadolol, oxprenolol, pindolol, timolol and atenolol were selected for study on the basis of in vivo beta-blocking potency. 3 Although all beta-blockers studied reduced the double product response to exercise, the pharmacodynamics of this effect differed markedly. 4 Pharmacodynamic half-lives, estimated for the drug tested, were 39 h for nadolol, atenolol 21 h, timolol 15 h, oxprenolol 13 h, propranolol 11 and pindolol 8 h. 5 These results suggest that the clinical choice of a beta-blocker with the least problems of compliance can be made on the basis of pharmacodynamics as well as pharmacological profile.

摘要
  1. 研究了25名人类志愿者单次口服六种β受体拮抗剂对运动诱导的双乘积(收缩压×心率)变化的影响。2. 根据体内β受体阻断效能,选择了三种剂量的普萘洛尔、纳多洛尔、氧烯洛尔、吲哚洛尔、噻吗洛尔和阿替洛尔进行研究。3. 虽然所研究的所有β受体阻滞剂都降低了运动时的双乘积反应,但这种效应的药效学有显著差异。4. 所测药物的药效学半衰期,纳多洛尔为39小时,阿替洛尔为21小时,噻吗洛尔为15小时,氧烯洛尔为13小时,普萘洛尔为11小时,吲哚洛尔为8小时。5. 这些结果表明,可根据药效学以及药理学特征来选择临床应用中依从性问题最少的β受体阻滞剂。
