"Methadone, in use since 1964 for the treatment of opioid dependence, may be dispensed only in federally approved Opioid Treatment Programs (OTPs). Treatment protocols require that a client take the medication at the clinic where it is dispensed daily.4 Take-home dosages are allowed only for clients who have been on an established maintenance program for an extended period of time.
"In October 2002, buprenorphine was approved by the Food and Drug Administration (FDA) for the treatment of opioid dependence. Physicians who obtain specialized training may prescribe buprenorphine. Some of these physicians are in private, office-based practices; others are affiliated with substance abuse treatment facilities or programs and may prescribe buprenorphine to clients at those facilities. Additionally, OTPs may also prescribe and/or dispense buprenorphine."
