Drugmaker Cephalon Inc. said Friday that a U.S. district court judge granted its request for a restraining order barring Mylan Inc. from launching a generic version of the muscle relaxant Amrix.
The temporary restraining order was granted by the U.S. District Court for the District of Delaware.
Cephalon and Mylan Inc. have been involved in a series of lawsuits since 2008 over the rights to market Amrix, an extended-release muscle relaxant. Generic drugmaker Mylan claims its generic version of the drug would not infringe on patents held by Cephalon.
"We remain confident in the strength of the patents protecting Amrix and believe we have a strong case on appeal," said Jerry Pappert, general counsel for Cephalon.
