RxNav Frequently Asked Questions (FAQs)

What are the main differences between the Web version of RxNav and the java version?

In terms of running RxNav, the Web version does not require the user to have java or java web start on the user's system. The web version of RxNav can be run on mobile devices, such as tablets and smart phones.
The web version in many ways tries to emulate the java version. Several new features are notable:
  • Searching. Searching can be done while visiting any tab in RxNav.
  • Search history. A clock icon to the right of the search bar provides the search history of successful searches and allows the user to conveniently revisit those searches.
  • NDC properties. The NDC tab not only contains the list of NDCs associated with the concept, but also properties for each NDC, such as the SPL set identifier, labeler, packaging, and a link to an image if available.
  • Links to DailyMed. The SPL set identifiers in the NDC and RxNorm property tables are linked to the DailyMed package inserts.
  • Simple View. The simple view has been redesigned to show the drug products underneath each ingredient, multiple ingredient or brand name.
  • Class View tab. The NDF-RT graphs (Drug, Disease, Ingredient, Mechanism of Action, Pharmacokinetics and Physiologic Effects) have been moved to the Class View tab. Each node in the graph can be moved around to create a different look to the graph.
  • Links to RxClass. The nodes displayed in the graphs in the Class View tab now are linked to RxClass. Clicking on a class node will bring up RxClass and show the drugs associated to that class.
  • Interactions. The interactions table has added a new column containing a description about the interaction.
  • Retired concepts. When searching for a drug using an RxCUI, RxNav will identify if that RxCUI is retired.
  • RxCUI display. The RxNorm identifier (RxCUI) is shown in the Classic or Simple Views by hovering over an entry.
