摘要：目的研究2种国产氨酚伪麻美芬片Ⅱ在健康人体内的药动学及生物等效性。方法20名健康男性受试者按2制剂双周期交叉试验设计口服受试制剂和参比制剂各2片,采用高效液相色谱-紫外法测定血浆中对乙酰氨基酚的浓度,高效液相色谱-质谱联用法测定血浆中伪麻黄碱和右啡烷的浓度,使用DAS软件计算药动学参数并进行生物等效性统计分析。结果参比制剂和受试制剂中对乙酰氨基酚的c_(max)分别为(6 600±s 1200),(7600±2100)μg·L^(-1);t_(max)分别为(1.1±0.6),(0.9±0.6)h;A4 UC_(0～16)分别为(27 900±4700),(28 700±4 400)μg·h·L^(-1);t(1/2)分别为(4.0±1.0),(4.2±1.4)h;伪麻黄碱的C_(max)分别为(213±33),(222±34)μg·L^(-1);t_(max)分别为(1.8±0.5),(1.6±0.6)h;AUC_(0～24)分别为(1 676±261),(1 659±282)μg·h·L^(-1);t_(1/2)分别为(4.6±0.5),(4.6±0.5)h;右啡烷的c_(max)分别为(7±4),(7.5±2.9)μg·L^(-1);t_(max)分别为(2.1±0.6),(1.9±0.7)h;AUC_(0～24)分别为(38±15),(39±12)μg·h·L^(-1);t_(1/2)分别为(6±3),(5.1±2.7)h。以AUC_(0～t)计算,受试制剂中对乙酰氡基酚、伪麻黄碱和右美沙芬的相对生物利用度分别为(103±8)%,(100±18)%,(109±27)%,2种制剂的主要药动学参数经统计学检验,差异无显著意义(P>0.05)。结论2种制剂具有生物等效性。

摘要：Ethaselen, an organoselenium compound designed and synthesized in the School of Pharmaceutical Sciences, Peking University, has been entitled to independent intellectual property rights both at home and abroad. As one of the novel antitumor drugs, ethaselen has been extensively studied in Phase I clinical trial, and its biological target is thioredoxin reductase. In this review, we focus on the ethaselen＇s efficacy and pharmacological actions, including antitumor effects both in vitro and in vivo, and immunologic functions. These research findings not only provide the theoretical basis for the anticancer study of ethaselen, but also guide the clinical trial of ethaselen.
