Rep. Young questions PBM merger

Rep. Don Young (R-Alaska) is the latest member of Congress to raise questions about a proposed merger between two pharmacy benefit managers.

Young raised questions about the merger of Express Scripts and Medco in a letter to Federal Trade Commission Chairman Jon Leibowitz.

Merging the two pharmacy benefit managers (PBMs) could have a "devastating" impact on community pharmacies, Young wrote. He said small pharmacies have little power when negotiating drug prices with PBMs.

"The combined 'synergies' of the merged entity may not lower drug costs," Young wrote. "It may simply create greater negotiating leverage to enable this new merged PBM to extract additional savings from other market participants, which has no guarantee of being passed on to plan sponsors and consumers."

Reps. John Conyers Jr. (D-Mich.) and Tom Marino (R-Pa.) have also raised concerns about the merger.
