A group of 35 state attorneys general signed on to an amicus brief supporting Oklahoma's laws regulating pharmacy benefit managers, published Oct. 18.
Led by Minnesota Attorney General Keith Ellison, the brief says that state regulation of PBMs can protect consumers from anti-competitive and abusive business practices.
The Pharmaceutical Care Management Association sued several Oklahoma state officials, alleging that federal laws preempted the state's laws regulating PBMs.
In April, a District Court judge ruled to uphold most of Oklahoma's laws. The Pharmaceutical Care Management Association is appealing the case.
Mr. Ellison led an amicus brief for a similar case challenging North Dakota's PBM regulations.
"The fact that a bipartisan coalition of 34 Republican and Democratic attorneys general came together to support Oklahoma in this fight is another sign that there is broad support across the country for regulating PBMs and bringing down the unconscionably high price of prescription drugs," Mr. Ellison said in a news release.
