NDC-classes

Overview

This dataset consists of the pharmaceutical classes used to classify drugs in the National Drug Code Directory maintained by the Food and Drug Administration between 1946 and 2017. The original data was downloaded from the FDA.

This is a temporal hypergraph dataset, which here means a sequence of timestamped hyperedges where each hyperedge is a set of nodes. Timestamps are in ISO8601 format. In the original dataset, 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.
