In a ruling that could pave the way for increased regulations by states such as Ohio, the U.S. Supreme Court on Thursday rejected a challenge of a 2015 Arkansas law putting restrictions on pharmacy benefit managers. We have overwhelming evidence that the PBM marketplace is highly dysfunctional and exceedingly costly, said Antonio Ciaccia, former lobbyist for the Ohio Pharmacists Association who is now with 3 Axis Advisors, a company set up to expose drug-pricing irregularities. With the industry problems growing worse, it is encouraging to see the Supreme Court assert the authority of states to control their own fates, rather than leaving their prescription drug costs and access in the hands of a largely unchecked multibillion-dollar industry.
