"Over the past year, we've seen far too many examples of drug companies raising prices excessively for long-standing, life-saving treatments with little or no new innovation or R&D," Clinton said in a statement.
The statement cited Mylan's EpiPen price increases as the latest example.
"This is not an isolated problem," the statement said. "Between 2008 and 2015, drug makers increased the prices of almost 400 generic drugs by over 1,000 percent.

Mylan basically has a monopoly on the delivery system, with Sanofi's Auvi-Q exiting the market last year due to a recall, and Teva's generic version failing to receive regulatory approval.
