Abstract

1 The effects of three day courses of propranolol 40 mg three times daily, atenolol 100 mg twice daily and labetalol 100 mg three times daily on antipyrine kinetics were examined in 13 normal subjects. 2 The mean antipyrine clearance initially was 41.3 +/- 12.4 ml/min (mean +/- s.d.) and fell to 35.0 +/- 12.1 ml/min following propranolol (P less than 0.025), 34.5 +/- 9.5 ml/min following atenolol (P less than 0.01), and 35.2 +/- 8.6 ml/min following labetalol (P less than 0.05). 3 The prolongation in antipyrine half-life was significant only following atenolol. Propranolol only caused a significant reduction in the volume of distribution of antipyrine. 4 These adrenoceptor antagonists appear to decrease antipyrine clearance in normal subjects. The reduction in antipyrine clearance was similar with all three drugs and appeared to be independent of the differing lipid solubilities and pharmacological profiles of the adrenoceptor antagonists examined.

摘要
  1. 在13名正常受试者中研究了每日三次服用40毫克普萘洛尔、每日两次服用100毫克阿替洛尔以及每日三次服用100毫克拉贝洛尔的三日疗程对安替比林动力学的影响。2. 安替比林的平均清除率最初为41.3±12.4毫升/分钟(平均值±标准差),服用普萘洛尔后降至35.0±12.1毫升/分钟(P<0.025),服用阿替洛尔后降至34.5±9.5毫升/分钟(P<0.01),服用拉贝洛尔后降至35.2±8.6毫升/分钟(P<0.05)。3. 仅在服用阿替洛尔后,安替比林半衰期的延长具有显著意义。普萘洛尔仅使安替比林的分布容积显著降低。4. 这些肾上腺素能受体拮抗剂似乎会降低正常受试者的安替比林清除率。三种药物对安替比林清除率的降低相似,且似乎与所研究的肾上腺素能受体拮抗剂不同的脂溶性和药理特性无关。
