@pharmatools/drug-data

Shared drug-data engine behind Pharmonym and PubCrawl. Deterministic, sourced, no AI.

• Name resolution — brand ⇄ generic, drug class and indications via RxNorm/RxNav, with openFDA fallback.
• Labels — dosage, warnings, contraindications, indications and adverse reactions from the US FDA label (openFDA, cited to DailyMed) and the UK/EU SmPC (eMC / medicines.org.uk).
• Comparison — equivalent US ↔ UK label sections mapped side by side.

Pure fetch + parse: no caching, no secrets. Wraps public government APIs. Dual-built (ESM + CJS), global fetch, Node ≥18.

Install

npm install @pharmatools/drug-data

Usage

import { resolveName, getLabels, compareLabels } from "@pharmatools/drug-data";

await resolveName("Lipitor");
// { inputType: "brand", genericName: "Atorvastatin", drugClass: "...", ... }

await getLabels("atorvastatin");
// { us: { dosage, warnings, ... , sourceUrl }, uk: { ... } }

await compareLabels("atorvastatin");
// { drug, comparisons: [{ topic, us, uk }], usSource, ukSource }

CommonJS consumers use require("@pharmatools/drug-data") — same API.

General (all-section) access

getLabels returns a compact 5-field view (uses, dosing, contraindications, warnings, adverse). For every available label section, use the general API:

import { getUsLabel, getUkSmpc } from "@pharmatools/drug-data";

await getUsLabel("atorvastatin");          // { drugName, setId, publishedDate, sections[], dailymedUrl }
await getUsLabel("atorvastatin", ["drug interactions"]); // filter to specific sections
await getUkSmpc("atorvastatin");           // { drugName, productId, sections[], url } — all SmPC sections
await getUkSmpc("atorvastatin", ["4.5"]);  // filter by section number or name

Each section is { code, title, content }.
