`fda_drug_approvals`

Pack: openfda · Endpoint: https://gateway.pipeworx.io/openfda/mcp

Find FDA-approved drugs by brand name, active ingredient, or application number. To find generic versions of a drug, search by active ingredient using products.active_ingredients.name (NOT openfda.generic_name — that field only works in the label endpoint). IMPORTANT: drug names in the FDA database are stored in UPPERCASE — always pass ingredient and brand names in uppercase (e.g. “APIXABAN” not “apixaban”) or you will get 0 results. Returns approval status, sponsor, application number (ANDA = generic, NDA = brand), and application details. There is NO queryable “application_type” field — never add application_type:“ANDA” (it returns 0 results). To limit to generics, search by active ingredient and read the ANDA/NDA prefix on application_number in the results. This endpoint has NO indication/disease field — for “drugs approved to treat ” use fda_drug_labels (which searches indications_and_usage); an indication phrase passed here is silently ignored and matches by drug name only.

Parameters

Name	Type	Required	Description
`query`	string	yes	OpenFDA drugsfda search query. Drug names MUST be UPPERCASE in quotes. To find all generics for a drug: ‘products.active_ingredients.name:“APIXABAN”’ (returns all ANDA + NDA approvals). By brand: ‘openfda.brand_name:“KEYTRUDA”’. By original submission: ‘submissions.submission_type:“ORIG”’. Do NOT use application_type (no such field — returns 0); ANDA vs NDA is read from the application_number prefix in the results, not filtered in the query. NOTE: use products.active_ingredients.name (not openfda.generic_name which is a label-API field and returns 0 here).
`limit`	number	no	Number of results (1-100, default 10)
