简介:健康志愿者10名,随机交叉口服硫酸吗啡控释片(CRMS)30mg(30mg×1)和硫酸吗啡普通片(IRMS)20mg(10mg×2),分别于服药前后各时点取静脉血,用GCMS测定血浆中吗啡含量。以药代软件程序处理,分别求得CRMS和IRMS的Cmax为19.38±3.80和21.27±6.21ng/ml;tmax为2.36±0.37h和0.55±0.16h;t1/2β为3.53±0.87h和3.03±0.74h,曲线下面积AUC为145.15±17.65和93.08±16.65ng·h/ml。癌症病人多次口服硫酸吗啡至稳态,CRMS和IRMS的峰浓度分别为27.43±0.33ng/ml,22.68±0.16ng/ml;谷浓度分别为19.45±1.44ng/ml;18.14±0.49ng/ml。
