Yes. In DIDB you can find if a drug is classified as an NTI drug. This information is available in the drug characteristics table by selecting “clinically significant NTI” in the Effect column. This list of NTI drugs is primarily classified based on information from regulatory agencies, including the EMA, FDA, PMDA, and Health Canada. Additionally, in the DDI Marker Studies Knowledgebase, NTI status is noted for substrate drugs, with references provided from both regulatory agencies and DrugBank.
