Pharmaceutical code

{{Short description|Drug identifier}} '''Pharmaceutical codes''' are used in medical classification to uniquely identify medication. They may uniquely identify an active ingredient, drug system (including inactive ingredients and time-release agents) in general, or a specific pharmaceutical product from a specific manufacturer.

==Examples==

Drug system identifiers (manufacturer-specific including inactive ingredients): * National Drug Code (NDC) — administered by Food and Drug Administration.<ref>{{cite web |date=5 May 2017 |title=National Drug Code Directory |website=U.S. Food and Drug Administration |url=https://www.fda.gov/drugs/drug-approvals-and-databases/national-drug-code-directory?elqTrackId=b2f8af5cd98146b19b56b47feab2f6a0&elq=b28e6c325c6748e1bc1f24989a3eb0d6&elqaid=4255&elqat=1&elqCampaignId=3344 }}</ref> * Drug Identification Number (DIN) — administered by Health Canada under the Food and Drugs Act * Hong Kong Drug Registration — administered by the Pharmaceutical Service of the Department of Health (Hong Kong) * National Pharmaceutical Product Index - South Africa

Proprietary database identifiers include those assigned by First Databank, Micromedex, MediSpan, Gold Standard Drug Database (published by Elsevier), and Cerner Multum MediSource Lexicon; these are cross-indexed by RxNorm, which also assigns a unique identifier (RxCUI) to every combination of active ingredient and dose level.<ref>[https://www.nlm.nih.gov/research/umls/rxnorm/overview.html RxNorm Overview]</ref>
