This dataset consists of the pharmaceutical classes used to classify drugs in |
|
the National Drug Code Directory maintained by the Food and Drug |
|
Administration. The original data was downloaded from |
|
https://www.fda.gov/Drugs/InformationOnDrugs/ucm142438.htm. Each simplex |
|
corresponds to an NDC code for a drug, where the nodes are the classes applied |
|
to the drug. Timestamps are in days and represent when the drug was first |
|
marketed. Note that the same drug substance can have more than one NDC code. For |
|
example, different dosages of the same drug may result in multiple NDC codes. |
|
|
|
|
|
The file NDC-classes-node-labels.txt maps the node IDs to the classes. |
|
|
|
The nth line in NDC-classes-simplex-labels.txt is the name of the drug |
|
corresponding to the nth simplex. |
