A Data Package which is a database of public and private sources of information on interventions related to clinical trials.
In addition, this README tries to provide some guidance on how one could take info from these multiple resources to create a new, normalized list of drugs.
One way to link at least some of these databases is through the NDC. The NDC, or National Drug Code, is a unique 10-digit, 3-segment number. It is a universal product identifier for human drugs in the United States. This is used by both DrugBank and FDA.
