Abstract

The cumulative urinary excretion over 24 h of pentazocine, under conditions of acidic urinary pH, has been measured in smokers and non-smokers using both male and female subjects (seventy subjects in total). A restricted urban population was studied. An overall three-fold inter-subject variation in elimination was observed. The cumulative urinary excretion of pentazocine was normally distributed in both smokers and non-smokers. Smokers metabolize 40% more pentazocine than non-smokers. It is concluded that induction is principally responsible for the observed subject variability.

摘要

在酸性尿pH条件下,对吸烟者和非吸烟者(共70名受试者,包括男性和女性)测定了喷他佐辛24小时的累积尿排泄量。研究对象为有限的城市人口。观察到消除过程中受试者间总体存在3倍的差异。喷他佐辛的累积尿排泄量在吸烟者和非吸烟者中均呈正态分布。吸烟者代谢的喷他佐辛比非吸烟者多40%。得出的结论是,诱导作用是观察到的受试者差异的主要原因。
