Zogenix files lawsuit against Massachusetts over painkiller ban

(Reuters) – Zogenix Inc said it sought a restraining order against an order by Massachusetts officials blocking sales of its FDA-approved painkiller, Zohydro. Massachusetts Governor Deval Patrick announced the Zohydro ban in late March, formally declaring a public health emergency stemming from the abuse of opioids in the state. The lawsuit, filed in the U.S. District Court in Massachusetts, follows an unanswered formal request to the Governor for a meeting to discuss the drug, the company said on Monday.
