Normalizes drug mentions extracted by OpenMed to RxNorm RxCUIs using the free public RxNav/RxNorm REST API. Use when the user wants to code, standardize, or de-duplicate medication names, resolve a brand/generic/ingredient to a stable RxCUI, link strength+dose-form to an SCD/SBD, attach NDCs, or build a US Core Medication resource. Trigger keywords: RxNorm, RxCUI, RxNav, drug normalization, medication coding, NDC, ingredient, SCD, SBD, brand vs generic, getApproximateMatch. Pairs after OpenMed…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Normalizing drug mentions to RxNorm
Map free-text medication mentions that OpenMed extracts to **RxNorm** — the U.S.
National Library of Medicine's normalized drug nomenclature. The unit of meaning
is the **RxCUI** (RxNorm Concept Unique Identifier): a stable integer that ties
together brand, generic, ingredient, strength, and dose form.
RxNorm and the **RxNav REST API** are **fully public and free**: no API key, no
license agreement, no rate-limit registration for normal use. Of every skill in
this terminology batch, this one has the highest value-to-friction ratio — start
here when grounding medications.
## When to use
- A clinical note names drugs ("metformin 500 mg", "Lipitor", "amox/clav") and
you need one stable code per drug for storage, analytics, or interoperability.
- You must distinguish **ingredient** ("metformin", `IN`) from a prescribable
product — **SCD** (Semantic Clinical Drug, generic) or **SBD** (Semantic Brand
Drug) — e.g. "metformin 500 MG Oral Tablet".
- You need to de-duplicate brand/generic synonyms onto one concept.
- You need **NDC** codes (package-level) for a product, or a US Core
`Medication`/`MedicationRequest` coded with RxNorm.

How to install
mdr add maziyarpanahi/openmed/normalizing-rxnorm@sha256:c9bef62955c8be9aThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
