experiment example 2
[0083] Experimental example 2 Research on the inhibitory effect of the drug group of the present invention on cytochrome P450 (CYP3A4 and CYP1A2)
[0084] The medicine group of the present invention is an antitussive medicine prepared from various traditional Chinese medicine ingredients such as Huajuhong, Aracea, orange peel, etc., and is widely used clinically because of its good effect of eliminating phlegm and relieving cough. The medicine group of the invention contains various chemical components such as flavonoids hesperidin, citral and monoterpene compounds. CYP3A4 is an important cytochrome P450 that catalyzes the metabolism of 60% of clinical drugs.
[0085] During the experiment, we surprisingly found that the drug group of the present invention has an inhibitory effect on CYP3A4 and CYP1A2, resulting in adverse drug interactions with catalytically metabolized drugs.
