(LAAM) Acetylmethadol (also referred to as /-alpha-acetylmethadol, methadyl acetate, LAAM or L-AAM) is structurally related to METHADONE. LAAM is a potent OPIOID agonist with properties similar to methadone, except for its prolonged half-life. This slow elimination can be useful clinically, since 50-80 milligram doses of LAAM given three times a week are equivalent to daily doses of 50-100 milligrams of methadone in preventing the symptoms of opioid WITHDRAWAL. Thus, addicts on maintenance treatment would need to come to a clinic only three times a week for LAAM instead of daily for methadone. Since the early 1970s, methadone has been the only agent approved for use in maintenance-treatment programs for HEROIN addicts, but research has shown that LAAM can be a useful alternative. In 1993, the U.S. Food and Drug Administration (FDA) initiated the legal changes needed to make LAAM available for clinical use.
