Health Matrix: Journal of Law-Medicine (forthcoming)

Congress has recently created a biosimilars approval pathway that would allow less expensive versions of biologic drugs to reach patients more quickly.

Is More Information Always Better? Mandatory Disclosure Regulations in the Prescription Drug Market
By Joanna Shepherd, Ph.D.

Cornell Law Review Online, Vol. 99, 2013 (March 1, 2013)

Pharmacy benefit managers (PBMs) save Americans billions of dollars each year by lowering the prices of prescription drugs and the costs of prescription drug coverage. However mandatory disclosure regulations recently enacted in several states and under the Affordable Care Act threaten to disrupt the cost savings PBMs currently produce for consumers. These regulations require PBMs to disclose competitively-sensitive financial information to various participants in the prescription drug market. The regulations foster tacit collusion and reduce PBMs’ ability to negotiate discounts with pharmacies and rebates with drug manufacturers. By disrupting competition in the prescription drug market, mandatory disclosure regulations will ultimately increase the prices that consumers pay for prescription drugs.

The regulatory scheme that was adopted by Mississippi in 2011, and is currently under legislative consideration in several other states, shifts regulatory control of PBMs from the neutral Insurance Commissions to the states’ Boards of Pharmacy. The fundamental problem with this structure is that the Boards of Pharmacy are made up of pharmacists, the direct market adversaries of PBMs.
