摘要: 目的:采用“Cocktail”探针药物法研究参松养心胶囊对大鼠体内4 种细胞色素P450(CYP450)亚型酶(CYP3A1、
CYP2D1、CYP2C11、CYP1A2)的影响。方法:大鼠灌胃给与低、中、高浓度参松养心胶囊,连续15 d,第16天各组大鼠腹腔注射
混合“Cocktail”探针药物(咪达唑仑、美托洛尔、奥美拉唑、咖啡因),测定大鼠给药前后体内4种探针药物的血药浓度并计算
各探针药物的药代动力学参数。结果:与空白组相比,低、中、高浓度参松养心胶囊对奥美拉唑、美托洛尔、咪达唑仑的药代
动力学参数影响显著,但对咖啡因的药代动力学参数无明显影响。结论:参松养心胶囊对CYP2C11、CYP2D1、CYP3A1酶活性
可能存在抑制作用,对CYP1A2酶活性作用不明显。

Abstract: Objective: To study the effects of Shensong-yangxin capsule on four subtypes of CYP450(CYP3A1, CYP2D1, CYP2C11
and CYP1A2)in rats by using the method of "Cocktail" probe drugs. Methods: Low, middle and high concentrations of Shensongyangxin
capsule were orally administered to rats for 15 days, respectively. On the 16th day, rats in each group were intraperitoneally
injected with "Cocktail" probe drugs (midazolam, metoprolol, omeprazole and caffeine), and plasma concentrations and
pharmacokinetic parameters of each probe were determined. Results: Compared with the control group, low, middle and high
concentrations of Shengsong-yangxin capsule had significant effects on the pharmacokinetic parameters of omeprazole, metoprolol and
midazolam decreased, but no significant influence in caffeine. Conclusion: Shensong-yangxin capsule has no obvious effects on the
activity of CYP1A2, and it may have inhibitory effects on the activities of CYP2C11, CYP2D1, and CYP3A1.

Key words: Shensong-yangxin capsule, "Cocktail" probe drugs, cytochrome P450
