In May, the Federal Trade Commission (FTC) required Hikma Pharmaceuticals PLC to divest its 23 percent interest in Unimark Remedies, Ltd. and its US marketing rights to a generic drug under manufacture by Unimark as a condition to allowing Hikma to complete its acquisition of Roxane Laboratories. The FTC was concerned that Hikma’s continued holding of a 23 percent interest in Unimark after consummation of its proposed acquisition of Roxane would create the incentive and ability for Hikma to eliminate future competition between Roxane and Hikma/Unimark in the sale of generic flecainide tablets (a drug used to treat abnormally fast heart rhythms) in the United States.
