PITTSBURGH - A federal judge in Pennsylvania on June 28 dismissed claims made by pharmacies and pharmacy trade groups that the consummated $29 billion merger of pharmaceutical benefit management (PBM) companies Express Scripts Inc. (ESI) and Medco Health Solutions Inc. gave the merged PBMs monopsony power as purchasers of retail community pharmacy services in state markets (National Association of Chain Drug Stores, et al. v. Express Scripts, Inc., et al., No. 2:12-cv-00395-CB, W.D. Pa.; 2013 U.S. Dist. LEXIS 90763).
