The document summarizes key projections about global spending on medicines from 2012 to 2016. It finds that global spending will reach nearly $1.2 trillion by 2016, with developed markets' share declining to 57% as pharmerging markets increase their share to 30% through population and economic growth. There will be an accelerated shift to generics and biosimilars, accounting for $4-6 billion, while off-invoice discounts and rebates are estimated to reach $180-190 billion in 2016, lowering estimated global spending. New medicines are expected to transform treatment for diseases like cancer and Alzheimer's, though some gaps in available treatments will remain.
