The first buprenorphine implant for maintenance treatment of opioid dependence has received FDA approval (http://1.usa.gov/1RuiaRi).
Previously, buprenorphine was approved for opioid dependence as a pill or film placed under the tongue or on the inside of the cheek until it dissolves. The pills and films are effective but can be lost, forgotten, or stolen. The 6-month implant may improve adherence for many people in recovery. It is intended for patients with prolonged clinical stability at a daily dose of 8 mg or less of oral buprenorphine.
