According to this illustration, the following statistics can be derived:
Manufacturers increase “wholesale” prices by 36.8% so they can give it to PBM and other middlemen as incentives to push their brands. These are commissions cloaked under politically correct terminology, i.e. “rebates.”
Retail pharmacies = 11%
Wholesalers and PBM’s = 7.3%
Commissions (Rebates) = 20.8%
Mail Order = 2%
PBM = 4.2%
