Generics The proliferation of brand drug "co-pay coupon" promotions, which lure insured consumers from generics to more expensive brands, will increase costs by $1.1 billion in the state of Michigan, USA, over the next decade for employers, unions and state employee plans, according to new research from Visante and released by the Pharmaceutical Care Management Association (PCMA). The use of these promotions by state and local government workers alone will cost Michigan taxpayers an extra $170 million over 10 years, the report notes. 17 November 2011
