DrugBank develops a biomedical knowledge platform for pharmaceutical research and clinical decision support. Its curated knowledge graph connects drugs, targets, diseases, clinical trials and commercial information. Biopharma OS lets research and portfolio teams search and analyze these relationships, while APIs, data products and an MCP interface supply structured information to software and AI agents. Its Clinical Intelligence API supports applications such as medication-interaction checking. DrugBank combines scientific curation with AI-assisted data processing; it supplies research and healthcare infrastructure rather than developing its own medicines.
