Last week, Senator Claire McCaskill of Missouri released a report showing that some of the most popular brand-name drugs have increased in price by, on average, 12 percent per year from 2012 to 2017 - 10 times faster than the inflation over those five years.
"Can you imagine if you went to an auto dealership and last year's exact model was being sold at a 20 percent mark-up, and then you went back the next year and it had happened again?" McCaskill said. "That's exactly what's happening in the prescription drug industry, where the cost of identical drugs skyrockets year after year."
