Exploring drug classes and their
RxNorm drug members
The RxClass Browser is a web application for exploring and
navigating through the class hierarchies to find the RxNorm drug
members associated with each class.
links drug classes of several drug sources including ATC, MeSH,
NDF-RT and FDA/SPL to their RxNorm drug members (ingredients,
precise ingredients and multiple ingredients).
RxClass allows users to search by class name or identifier to
find the RxNorm drug members or, conversely, search by RxNorm
drug name or identifier to find the classes that the RxNorm drug
is a member of.
