摘 要 目的:建立测定大鼠血浆中柳氮磺吡啶(SSZ)代谢产物磺胺吡啶(SP)浓度的方法,并探讨艾司奥美拉唑(ESOM)对SSZ在大鼠体内药动学行为的影响。方法:将雄性SD大鼠随机分为SSZ组和SSZ+ESOM组,每组6只。SSZ+ESOM组大鼠连续灌胃艾司奥美拉唑肠溶片[90 mg/(kg·d)]14天;第15天時,两组大鼠单次灌胃柳氮磺吡啶肠溶片(90 mg/kg),并在给药后0.5、1、1.5、2、3、4、6、8、10、12、24、36、48、72 h时于其眼内眦取血。血浆经甲醇沉淀蛋白后,以地西泮为内标,以Agilent XDR-C18为色谱柱,以甲醇-0.1%甲酸溶液(梯度洗脱)为流动相,采用液相色谱-串联质谱法检测血浆中SSZ代谢产物SP的浓度;采用DAS 3.0.1软件计算药动学参数并进行组间比较。结果:SP检测质量浓度的线性范围为2~1 000 ng/mL,方法学考察结果符合《中国药典》相应要求。SSZ+ESOM组和SSZ组大鼠体内SP的AUC0-t、tmax、t1/2z、cmax、MRT0-t等药动学参数比较,差异均无统计学意义(P>0.05)。结论:所建方法简便、快速、灵敏度高,可用于血浆中SSZ代谢产物SP浓度的检测;ESOM对SSZ在大鼠体内的药动学行为无明显影响。

ABSTRACT   OBJECTIVE: To develop a method for determining the plasma concentration of sulfasalazine (SSZ) metabolite sulfapyridine (SP) in rats, and to investigate the effects of esomeprazole (ESOM) on the pharmacokinetic behavior of SSZ in rats. METHODS: Male SD rats were randomly divided into SSZ group and SSZ+ESOM group, with 6 rats in each group. SSZ+ESOM group were given Esomeprazole enteric-coated tablets [90 mg/(kg·d)] intragastrically for 14 days. On the 15th day, the rats in 2 groups were given Sulfasalazine enteric coated tablets (90 mg/kg) intragastrically, and blood sample was collected from the inner canthus at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72 h after administration. After protein precipitation with methanol, using diazepam as internal standard, Agilent XDR-C18 column was adopted with methanol-0.1% formic acid solution (gradient elution) as mobile phase. The concentration of SSZ metabolite SP in plasma was determined by LC-MS/MS. The pharmacokinetic parameters were calculated by using DAS 3.0.1 software and compared between 2 groups. RESULTS: The linear range of SP were 2-1 000 ng/mL. The methodology met the requirements of Chinese Pharmacopeia. There was no statistical significance in pharmacokinetic parameters of SP between 2 groups, such as AUC0-t, tmax, t1/2z, cmax, MRT0-t (P>0.05). CONCLUSIONS: The established method is simple, rapid and sensitive; it can be used for the concentration determination of SSZ metabolite SP in plasma. ESOM has no significant effect on the pharmacokinetic behavior of SSZ in rats.

质子泵抑制剂(proton pump inhibitors,PPIs)因高效的抑酸作用而被广泛用于胃肠道疾病的临床治疗。目前,PPIs除用于治疗胃食管反流病、胃十二指肠溃疡和幽门螺杆菌感染等疾病外,还被用于预防由非甾体抗炎药(non-steroidal anti-inflammatory drugs,NSAIDs)引发的胃溃疡疾病[1]。类风湿关节炎(aheumatoid arthritis,RA)是一种全身性自身免疫疾病,其特征为多关节的慢性炎症、骨侵蚀和软骨破坏[2]。柳氮磺吡啶(sulfasalazine,SSZ)是传统的合成类抗风湿药物,是治疗RA的基石药物,临床通常在使用SSZ的基础上根据患者的病情联合使用NSAIDs[3]。近年……
