The United States Food and Drug Administration has launched a new open data site called openFDA.  The site is currently in Beta testing, and provides API access to over 3 million adverse drug event reports.  The API url can be modified to query a wide variety of data parameters ranging from drug details, to indications, to date ranges.

The video embedded above demonstrates the process by which to pull data into Excel using the openFDA API.  Below are a few links from the video:
