In Re: Metoprolol Succinate Direct Purchaser Antitrust Litigation

The plaintiffs were a class of direct purchasers of the brand name prescription drug Toprol XL, a drug used for the treatment of heart disease. They alleged that the defendants violated antitrust laws by improperly delaying the market entry of cheaper generic substitutes to Toprol XL.

Econ One was retained by counsel for the plaintiffs. Dr. Jeffrey Leitzinger submitted an expert report relating to class certification issues. Those issues included the likely impact of a delay in generic competition on the class members, the availability of common, class-wide economic evidence and methodologies that would demonstrate class-wide impact in the form of overcharges, and whether those overcharges could be calculated as a whole on an aggregate basis using reliable methodologies.  The case was settled prior to trial.
