AUGUSTA –– The Maine Senate narrowly passed a bill Thursday that would lower prescription drug prices by requiring brand-name pharmaceutical producers to provide samples of their drugs to generic producers. The bill, sponsored by Sen. Troy Jackson, D-Allagash, would align with federal law and, hopefully, stimulate the production of generic and less expensive alternatives once a brand-name drug’s patent expires. “The high cost of medicine is a burden on Mainers all over our state, all while Big Pharma makes an obscene fortune on the backs of our families” Jackson said.
