目的:探讨手性药物左西替利嗪与西替利嗪对氨茶碱代谢的影响。方法采用反相高效液相色谱法,色谱柱为 Hypersil BDS C18柱(250 mm ×4.6 mm,5μm),流动相为水-甲醇(85:15),流速为1.0 mL / min,柱温为35℃,检测波长为275 nm。SD 大鼠,随机分为单用氨茶碱组(APL 组)、左西替利嗪+氨茶碱组(LCZ + APL 组)和西替利嗪+氨茶碱组(CZ + APL 组),每组8只(雌雄各半)。分别在给药0,2,4,6,8 h 时采血测定氨茶碱的血药浓度,分析药代动力学参数。结果与 LCZ + APL 组比较,APL 组氨茶碱的给药后初始血管浓度( Co)、消除速率常数(Ke)、药物半衰期( t1/2)、清除率( CL)、药时曲线下面积( AUC)、表观分布容积( Vc)有显著性差异( P <0.01或P <0.05)。与 CZ + APL 组比较,APL 组氨茶碱的 Ke,t1/2,CL,AUC 有显著性差异( P <0.05),而 Co 及 Vc 无显著差异( P >0.05)。与LCZ + APL 组比较,CZ + APL 组氨茶碱的 Ke,CL,Co,AUC 有显著性差异( P <0.01或 P <0.05),t1/2无显著性差异( P >0.05)。结论左西替利嗪与西替利嗪均可使氨茶碱的血药浓度升高、代谢率减慢,同时西替利嗪使氨茶碱血药浓度升高的作用比左西替利嗪更明显。

Objective To investigate the effects of chiral drug cetirizine and levocetirizine on the metabolism of aminophylline in rats. Methods The plasma concentration of aminophylline was detected by RP - HPLC with a BDS C18 column(250 mm × 4. 6 mm,5 μm). The mobile phase was water - methanol solution(85 : 15)at a flow rate of 1. 0 mL / min. The column temperature was 35 ℃. The detec-tion wavelength was 275 nm. The SD rats were randomly divided into the aminophylline group(APL group),levocetirizine plus amino-phylline group(LCZ + APL group)and cetirizine plus aminophylline group(CZ + APL group),8 rats in each group. The plasma concentra-tion of the aminophylline in rat was detected at the different timepoints of 0,2,4,6,8 h after administration and the pharmacokinetic parameters were analyzed. Results The initial plasma concentration( C0),elimination rate constant(Ke),half life( t1 / 2),clearance rate ( CL),area under curve( AUC)and apparent volume of distribution( Vc)of aminophylline had statistical differences between the APL group and the LCZ + APL group( P < 0. 01 or P < 0. 05). Ke,t1 / 2,CL and AUC of aminophylline had statistical differences between the APL group and the CZ + APL group( P < 0. 05),but C0 and Vc represented no difference( P > 0. 05). Ke,CL,C0 and AUC of aminophylline had statistical differences between the CZ + APL group and the LCZ + APL group,without including t1 / 2( P > 0. 05). Conclusion Levocetirizine and cetirizine both can elevate the plasma concentration and decrease the metabolic rate of amino-phylline. Furthermore,the effect of cetirizine for elevating blood aminophylline concentration is more significant than that of levocetirizine.
