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.
