Three major drug middlemen needlessly marked up generic drugs for cancer, HIV, and multiple sclerosis to generate $7.3 billion in revenue, The Federal Trade Commission (FTC) said in a report released today.

The nation's three largest pharmacy benefit managers have significantly marked up the prices of certain medicines, including for heart disease, cancer and HIV, at their affiliated pharmacies, the U.S.

Pharmacy benefit managers, which serve as the middlemen between drug makers, insurers and pharmacies, reaped $7.3 billion in revenue from marking up the prices of dozens of specialty generic drugs between 2017 and 2022,

Optum RX, CVS Caremark and Express Scripts are marking up drugs that treat cancer and multiple sclerosis by more than 1,000-percent.
