GM is involved in substance metabolism, especially the biotransformation of pharmaceuticals. It modulates drug pharmacological activity and bioavailability through various metabolic pathways. Since traditional Chinese medicine (TCM) is primarily administered orally, its active compounds inevitably interact with the GM. This review systematically explores the bidirectional interplay between TCM and GM. GM metabolizes TCM components via enzymatic reactions (e.g. hydrolysis, reduction, and deconjugation) and interactions with metabolites, thereby enhancing bioavailability and sometimes modifying pharmacological properties. Conversely, TCM influences GM composition and function by promoting beneficial taxa, restoring microbial balance, and regulating microbial metabolites such as short-chain fatty acids and bile acids. The TCM-GM interaction shows promise in treating chronic diseases, such as inflammatory bowel disease, mental disorders, and cardiovascular diseases. However, challenges remain in fully understanding these interactions due to the complexity of TCM formulations and individual variations in GM composition. Future research should employ multi-omics approaches to develop personalized TCM therapies based on individual GM profiles.</p>","PeriodicalId":11307,"journal":{"name":"Drug Metabolism Reviews","volume":" ","pages":"1-24"},"PeriodicalIF":3.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Troglitazone metabolism via CYP3A4 and CYP2C8 generates a reactive quinone metabolite, depleting glutathione (GSH), elevating mitochondrial oxidative stress, and inducing hepatotoxicity. Glitazones also undergo GSH conjugation through open-ring formation, influencing detoxification and toxicity. Inflammation downregulates CYP enzymes and transporters, altering drug clearance and increasing drug-drug interaction (DDI) risks. Ketoconazole and troleandomycin inhibit rosiglitazone metabolism by 52% and 40%, respectively, while pioglitazone inhibits CYP2C8-mediated arachidonic acid metabolism, impairing renal function. Gemfibrozil further increases pioglitazone's area under the curve (AUC) threefold by inhibiting CYP2C8. Additionally, rosiglitazone modulates OATP1B1, enhancing pravastatin uptake at low concentrations but inhibiting it at higher levels, affecting plasma levels. Troglitazone inhibits organic anion-transporting polypeptide 1B1 (OATP1B1) mediated rosuvastatin uptake, reducing hepatic delivery and efficacy, necessitating strategic drug combinations. Furthermore, new PPARγ modulators are being developed via selective and partial activation to mitigate toxicity, incorporating non-thiazolidinedione scaffolds and optimizing DMPK properties through nanocarriers such as lipid-based nanoparticles.
