1 Following a single oral dose of amylobarbitone sodium it has been shown that a group of young subjects convert a higher proportion of the dose to 3'-hydroxyamylobarbitone than a group of elderly subjects. 2 Twenty-four hours after the administration of the drug, the mean plasma level of amylobarbitone in the elderly group is significantly higher than in the group of young subjects. 3 It is concluded that the rate of hydroxylation of amylobarbitone sodium decreases with age.
给一组年轻受试者单口服一剂氨基丁二酰脲钠后发现,与另一组老年受试者相比,该组年轻受试者将更高比例的剂量转化为 3'-羟基氨基丁二酰脲。
给药 24 小时后,老年组的氨基丁二酰脲平均血浆水平明显高于年轻组。
结论是,氨基丁二酰脲钠的羟化率随年龄增长而降低。
