Example prompt: Can you look up the RxNorm profile for metformin — I need its RxCUI identifier, the brand names it's sold under, and what dose forms are available?

## When to prefer this

Choose this endpoint when you need a structured, standardized RxNorm profile for a known drug or ingredient name — specifically when you need the RxCUI identifier, brand name enumeration, ingredient breakdown, or dose form list. Prefer this over the fuzzy-match sibling endpoint when the drug name is already spelled correctly. Use this over general drug databases when RxNorm-compatible identifiers are required for clinical or interoperability workflows.

## Known failure modes

- Drug name not found in RxNorm returns null fields or empty arrays
- Misspelled or unrecognized drug names may return degraded results
- Brand-only names not mapped to ingredients may return incomplete ingredient lists
- Network or upstream RxNorm API unavailability causes request failure
- Missing required 'name' query parameter returns a validation error

## How this service works

RxNorm profile of a drug name: ingredient, brand names and available dose forms, with the RxCUI identifier.

## Output

Returns a structured drug profile including: the drug's RxCUI identifier, normalized name, term type (e.g. ingredient or brand), list of ingredients with their RxCUIs, list of brand names with RxCUIs, available dose forms with RxCUIs, a summary, source URL, brand count, and optional disclaimer. May include a degraded flag if data quality is reduced.
