In a randomized crossover study the bioavailability of a single dose of digoxin and of beta-methyl-digoxin tablets was tested in four normal volunteers. No difference was found between the two products in the rate and extent of drug absorption using 6 day cumulative urinary excretion and serial serum concentration measurements.
在一项随机交叉研究中,对4名正常志愿者测试了单剂量地高辛和β-甲基地高辛片剂的生物利用度。通过6天累积尿排泄量和系列血清浓度测定,发现两种产品在药物吸收速率和程度上没有差异。
