The current definition of Product in the Editorial Guide July 2016: "This hierarchy was introduced as a top-level hierarchy in order to clearly distinguish drug products (products) from their chemical constituents (substances). It contains concepts that represent the multiple levels of granularity required to support a variety of uses cases such as computerized provider order entry (CPOE), e-prescribing, decision support and formulary management. The levels of drug products represented in the International Release include Virtual Medicinal Product (VMP), Virtual Therapeutic Moiety (VTM), and Product Category.” It was determined at the EAG meeting in Wellington, October 2016 that this definition needs to be revised to be in line with the proposed Drug Model and those used by other national drug models.
This discussion page has been set up to allow suggested revisions and comments to the current definition.

Discussion with the NLM has determined that there is not an official definition for products published with RxNorm.
The UMLS definition of product is derived from the NCI BRIDG model:
"A thing produced by or resulting from a process. EXAMPLE(S): drug, device. The FDA list of regulated products: animal and human drugs; therapeutic biologics; allergenics; cell, tissue and gene therapy products; blood components; blood derivative products; devices; and animal (pets and livestock) and human food/feed (medicated and un-medicated); cosmetics; pet treats; and dietary supplements."
