Drug coding - Valiance Health

Drug coding runs through POST /api/v1/search/ with domain: "Drug".

Vocabulary	Parameter value	Status
RxNorm	`RxNorm`	Available

Code a drug

curl https://api.v2.healthproximate.com/api/v1/search/ \
  -H "X-API-Key: hpx_..." \
  -H "Content-Type: application/json" \
  -d '{
    "query": "augmentin 625mg",
    "domain": "Drug",
    "vocabulary": "RxNorm",
    "limit": 5
  }'

Brand names resolve toward their ingredient and clinical-drug concepts, so augmentin finds amoxicillin/clavulanate concepts even when the exact brand string is absent.

Practical notes

Granularity: RxNorm carries ingredient, clinical drug, and branded levels. Pick the level your downstream system expects and filter candidates by concept class.
Local products: Malaysian trade names not in RxNorm resolve via ingredient matches. Review low-score candidates before use.
Supply items are not drugs: consumables and implants (stents, dressings) live in the Device/supply space, not RxNorm — a drug search will not find them.
