FDA Drug Database

Project description

travis pypi codecov requiresio

A Django wrapper for fda.gov National Drug Code (NDC) database. fdadb stores each row under one name MedicationName object instead of having multiple drugs with the same name next to each other, for example: In the NDC database there are around 21 Viagras (with different strengths) so in such case we save the MedicationName: Viagra and under this name we store all the 21 instances. This allows for better user experience when searching through the list of drugs.

Setting Up

  • pip install fdadb
  • Add fdadb to your INSTALLED_APPS
  • ./manage.py migrate fdadb
  • ./manage.py fetch_ndc_database - might take 15-30 minutes (the command will fetch all items from FDA database and save it in your project)

API:

All APIs are searchable with ?q=term query param.

medications/

Returns list of MedicationName objects (pass ?q=termtosearch to filter the results), this API supports ElasticSearch for fast querying. Pagination does not work yet when ElasticSearch is enabled (in most cases this does not cause any issues, as this API is generally used for drug autocomplete). You can change the autocomplete limit by setting FDADB_AUTOCOMPLETE_LIMIT in your Django configuration (default: 10).

The ElasticSearch uses ngram for the query parameter.

medications/(?P<medication_name>[w-]+)/strengths

Returns list of medication strengths

medications/(?P<medication_name>[w-]+)/strengths/(?P<strength_id>[d-]+)/ndcs

Returns list of Medication NDCs

ElasticSearch

To enable support of ElasticSearch in autocomplete, set:

  • ELASTICSEARCH_URL in project configuration
  • Run ./manage.py fdadb_es_index` after fetching the NDC database (use ``--drop_indexes in case you want to cleanup the medications index)

Manage.py commands

  • ./manage.py fdadb_es_index - indexes the products into ElasticSearch
  • ./manage.py fetch_ndc_database - fetches products data from NDS DB and saves in the database

Support

  • Django 1.11, 2.1, 2.2
  • Python 3.4-3.6
