KEGG MEDICUS Drug Interaction Checker
Drug Interaction Database
The KEGG drug interaction database contains known adverse drug-drug interactions associated with contraindications (CI) and precautions (P). The interaction data are first extracted from the package inserts (drug labels) of all prescription drug products in Japan and then generalized as interactions between active ingredients using the KEGG DRUG D number identifiers. The database currently contains over 260,000 interactions (D number pairs) involving more than 4,000 drugs (D number entries) together with annotation about CYP enzymes, overlapping targets, etc.Drug Interaction Checker
