New Drug Interactions API coming October 1

drug interaction A new drug interactions API will be introduced on October 1. Stay tuned!

At the same time, the NDF-RT data will be updated to the latest release which no longer contains drug interactions. The old NDF-RT drug interactions will not be part of the new interactions API.

The RxClass API is here!

The RxClass API is a web service for accessing drug classes and associated drug members. The RxClass Browser uses the API for exploring and navigating through the class hierarchies to find the RxNorm drug members associated with each class. The RxClass API is available as both a SOAP interface and as RESTful resources.
