Warren, NJ, May 18, 2018 – Aquestive Therapeutics today announced that a settlement agreement has been reached resolving patent litigation related to SUBOXONE® (buprenorphine and naloxone) Sublingual Film. Indivior PLC and its U.S. subsidiary, Indivior Inc., marketers and distributors of SUBOXONE®, joined partner Aquestive in the settlement with Par Pharmaceuticals Inc., an operating company of Endo International PLC and IntelGenx Technologies Corp.
