normalizing-rxnorm
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 NER: consume Pharmaceutical/Chemical entities from openmed.analyze_text and map each drug span to an

Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 do I install it?
Run `npx skills add maziyarpanahi/openmed --skill normalizing-rxnorm --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From maziyarpanahi/openmed, a repository with 4,851 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
