Compared with methadone, a Schedule II medication that must be administered at methadone clinics, buprenorphine has a lower risk of diversion and overdose, Petros Levounis, M.D., director of this course, told Psychiatric News. "Based on our experience with buprenorphine so far, 95 percent of patients surveyed [in a recent study] felt buprenorphine was very or extremely helpful, and 60 percent were still in treatment after the first six months," he said.
