Two companies that distribute pharmaceutical opiates have filed an emergency petition before an appeals court to vacate a court order that allowed public access to a wide-ranging federal drug distribution database this week.

McKesson Corp. and AmerisourceBergen Drug Corp. filed an emergency petition for writ of mandamus Thursday before the U.S. Court of Appeal for the Sixth Circuit that said U.S. District Judge Dan Polster of the Northern District of Ohio abused his discretion in lifting his protective order over the database, which prompted a firestorm of media publicity.
