Pharmaceutical US legislation that requires manufacturers of brand-name drugs to provide new discounts and rebates for drugs purchased through Medicare and Medicaid, with the amount of those discounts and rebates based on the prices of the drugs, will see overall prices rise, according to estimates by the USA' Congressional Budget Office (CBO). Manufacturers thus have an incentive to raise those prices to offset the costs of providing the new discounts and rebates, although other forces will limit their ability to do so, it states. 10 November 2010
