Nearly 90 percent of prescription drugs dispensed in the United States are generic drugs. According to FDA, an increasing volume of generic drug applications over the past decades stressed its ability to review applications efficiently. GDUFA granted FDA the authority to collect user fees from the generic drug industry to supplement resources for the generic drug program. In return, FDA committed to meeting certain performance goals related to the timely review of generic drug applications and to implementing review process improvements. GAO was asked to examine FDA's implementation of GDUFA. In this report, GAO (1) examines how user fees supported the generic drug program, (2) describes FDA's improvements to the generic drug application review process, and (3) analyzes changes in generic drug application review times. GAO reviewed laws and regulations; FDA policy, guidance, the GDUFA Commitment Letter, and GDUFA financial reports from fiscal years 2013 through 2016; FDA data on application review times from fiscal years 2012 through 2015; and interviewed officials from FDA, generic drug manufacturers, and trade associations.
