Senators were dismayed at a recent report that found extraordinary price hikes for 300 generic drugs, saying the report highlights serious problems with the pharmaceutical industry.

The report, released by the federal watchdog Government Accountability Office, found that 300 of 1,441 generic drugs analyzed had at least one price hike of 100 percent or more from 2010 to the first quarter of 2015. However, generic drug prices overall fell 59 percent from 2010 to 2015.
