Abstract

Antipyrine clearance was measured before and 1 day after administration of a single intramuscular dose of recombinant human leukocyte alpha A interferon. In the nine patients studied, antipyrine clearance was reduced after interferon from 0.49 (0.21-1.13) ml kg-1 min-1 (median (range)) to 0.41 (0.20-1.07) ml kg-1 min-1, P less than 0.01. In individual patients, the decrement in antipyrine clearance was variable, ranging from 5-47% (median, 16%). This study provides the first direct evidence that interferon inhibits hepatic oxidative drug metabolism in humans and alerts clinicians to the possibility of potentially toxic drug-drug interactions.

摘要

在单次肌肉注射重组人白细胞αA干扰素之前及之后1天,测定安替比林清除率。在研究的9名患者中,干扰素注射后安替比林清除率从0.49(0.21 - 1.13)毫升·千克⁻¹·分钟⁻¹(中位数(范围))降至0.41(0.20 - 1.07)毫升·千克⁻¹·分钟⁻¹,P<0.01。在个体患者中,安替比林清除率的下降幅度各不相同,范围为5% - 47%(中位数为16%)。本研究提供了首个直接证据,表明干扰素会抑制人体肝脏的氧化药物代谢,并提醒临床医生注意潜在的毒性药物相互作用的可能性。
