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天时,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.
