# Search EU authorised medicines

`GET /v1/sources/ema-article-57/search`

## Request

- Base URL: `https://api.assyro.com`
- URL: `https://api.assyro.com/v1/sources/ema-article-57/search`
- Auth: none declared

Search every medicine authorised in the EU/EEA and Northern Ireland, centrally AND nationally, from EMA's Article 57 product data (Assyro's weekly copy): product name, active substance, route of administration, authorisation country and marketing authorisation holder, one row per product, route and country. Use it for whether or where a medicine or substance is authorised in a member state, which companies hold national authorisations for a substance, or the national brand names of a generic. Country "European Union" means centrally authorised (its EPAR is in search_ema). The file has no authorisation numbers, dates, strengths or forms. Call read_eu_authorised_medicine for a row and every other row of the same product name.
