stereoselective pharmacokinetics of the nonsteroidal anti-inflammatory drug, tiaprofenic acid (5-benzoyl-alpha-methyl-2-thiopheneacetic acid), in four arthritic patients receiving 200 mg/8 h of the racemic drug. Synovial concentrations of the enantiomers were also measured following administration of single 200-mg doses of the drug to six other patients. In the analytical procedure, racemic tiaprofenic acid was
气相色谱法用于研究四名接受200 mg / 8 h外消旋药物的关节炎患者中非甾体类抗炎药噻洛芬酸(5-苯甲酰基-α-甲基-2-噻吩乙酸)的立体选择性药代动力学。在向另外六名患者施用单次200 mg剂量的药物后,也测量了对映体的滑液浓度。在分析过程中,将外消旋噻洛芬酸与(S)-(+)-苯异丙胺偶联,并拆分了相应的非对映异构酰胺衍生物。对稳定状态下的一系列血液和尿液样本以及单个滑膜样本的分析显示,噻洛芬酸对映体具有重叠的血浆浓度-时间和尿排泄时间曲线以及等效的滑膜浓度。这些结果表明,
