Acceptability of methadyl acetate (LAAM) as compared with methadone in a treatment program for heroin addicts

Abstract

Heroin addicts who had been maintained for at least three months on LAAM (levo-alpha-acetylmethadol, methadyl acetate) and at least three months on methadone were asked to compare the two drugs on a number of criteria. The responses were highly selective, indicating that a desire to please the investigators was not an important factor. Overwhelmingly, the majority of patients reported that LAAM provided better heroin "blockade", that it was more effective in reducing craving, and that actual use of heroin was less on LAAM than on methadone. In other respects, such as sexual performance, sleep, and appetite, most patients perceived no difference between the drugs. In no respect was methadone preferred by a majority, although methadone was viewed more favorably on some criteria by some patients. These findings indicate that for most heroin addicts LAAM will be an acceptable maintenance drug.
