Case report of barbiturate-induced enhancement of methadone metabolism and withdrawal syndrome
SJ Liu and RI Wang
A methadone maintenance patient with a decreased plasma methadone level,
possibly due to phenobarbital-induced acceleration of methadone
biotransformation, experienced opioid withdrawal symptoms. This finding
suggests that when phenobarbital is used with methadone the plasma
methadone level must be monitored.
