Friday, the FDA approved a new implant that treats opioid addiction. The implant— called Probuphine — is a system of matchstick-sized rods inserted under the skin that offers controlled release of buprenorphine, a drug already used in the treatment of opioid addiction. Because it’s implanted, this version can’t be sold on the black market. FYI, buprenorphine is the third-most confiscated drug by the DEA. The approval comes in the midst of an opioid epidemic in the U.S., where the rate of overdose deaths involving opioids has quadrupled in the last 15 years. Still TBD, whether the cost of Probuphine can compete with other treatments.
