The US spends more on prescription drugs than any other country in the world. It’s easy to blame drugmakers, but they’re by no means the only ones at fault. Lowering costs will also require lawmakers to scrutinize pharmacy benefit managers, the middlemen in a bewilderingly opaque supply chain.

PBMs started in the 1960s as a “back office” for health plans to process claims.
