Dihydrocodeine: a useful tool in the detoxification of methadone-maintained patients.

ABSTRACT

We investigated the merit of dihydrocodeine tartrate for withdrawal in detoxifying 20 methadone-maintained patients presenting for treatment at the Leeds Addiction Unit (LAU). Thirteen patients (65%) successfully completed methadone detoxification and were abstinent from both methadone and opiate-type drugs at the end of the 2-week program. On completion, three patients began treatment with Naltrexone and another was abstinent at a follow-up appointment, 1 week later. A further patient relapsed back to heroin use but remained in contact with the LAU. The remaining six patients dropped out of the 2-week detoxification program between days 3 and 11 of the dihydrocodeine cross-over period. We believe dihydrocodeine may have advantages in detoxifying methadone-maintained patients.
