Abstract

The pharmacokinetics and pharmacodynamics of propranolol (80 mg by mouth) were studied in seven extensive and four poor metabolisers of debrisoquine. Evidence for impairment of the 4'-hydroxylation of propranolol was found in poor metabolisers. However, no significant difference was detected in the oral clearance of unchanged drug between the two groups of debrisoquine oxidation phenotypes. Poor metabolisers of debrisoquine did not experience more intense or more prolonged beta-adrenoceptor blockade than extensive metabolisers of debrisoquine.

摘要

对7名异喹胍广泛代谢者和4名异喹胍代谢不良者研究了普萘洛尔(口服80毫克)的药代动力学和药效学。在代谢不良者中发现了普萘洛尔4'-羟基化受损的证据。然而,两组异喹胍氧化表型之间未观察到未改变药物口服清除率的显著差异。异喹胍代谢不良者与异喹胍广泛代谢者相比,并未经历更强烈或更持久的β-肾上腺素能受体阻滞。
