What types of biomedical data can I find on DrugBank?
DrugBank (go.drugbank.com) organizes its content around a single biomedical knowledge base that links drugs, targets, diseases, and trials. If you need to check whether a specific compound, protein target, disease area, or clinical trial is covered, the four categories below are where that information lives. The site is positioned as a "trusted intelligence operating system" for drug discovery and clinical decision-making, so the data is structured for cross-referencing rather than as isolated lists.
Drug data
This is the core of the knowledge base. Drug entries typically connect a compound to its identity, mechanism, and relationships to other biomedical entities. In practice, this means you can look up a drug and follow links outward to what it acts on and what conditions it is associated with, rather than reading a standalone monograph.
Targets
Target information covers the biological molecules drugs act on. Because targets are linked to drug entries, this category is most useful when you want to move in the reverse direction: start from a target and see which drugs are associated with it. This supports questions like "what compounds interact with this protein" rather than only "what does this drug do."
Diseases
Disease data connects conditions to the drugs and targets associated with them. This is the category to check when your question is indication-driven — for example, whether a particular disease area is represented and which drugs or targets map to it.
Clinical trials
Trial data is included alongside the drug, target, and disease content. This matters if you need to connect a compound or condition to trial-level information within the same knowledge base, instead of switching to a separate registry.
How the categories work together
The value of DrugBank is the integration, not any single category. The table below summarizes what each category answers and how it links to the others.
| Data type | Question it answers | Links to |
|---|---|---|
| Drugs | What is this compound and what is it associated with? | Targets, diseases, trials |
| Targets | Which drugs act on this molecule? | Drugs, diseases |
| Diseases | Which drugs and targets relate to this condition? | Drugs, targets |
| Trials | What trial information connects to this drug or disease? | Drugs, diseases |
Before you rely on it
Coverage and access terms are not fully specified in the available site information. The site references a pricing page, so some content or features may sit behind a subscription rather than being openly available. If your decision depends on a specific drug, target, disease, or trial being present, verify that entry directly on the site and confirm whether your access level includes it.
