Abstract

The levels of dihydrocodeine found in impaired individuals and in fatalities show a wide overlap in the ranges. Among other factors, the genetically controlled metabolism of dihydrocodeine should play an important role in dihydrocodeine toxicity. For the first time, the most important metabolites of dihydrocodeine were investigated in femoral blood from three fatal cases by simultaneous determination using HPLC and native fluorescence for detection. The amount of parent drug always exceeded dihydrocodeine-glucuronide formation and dihydromorphine concentrations ranged from 0.16-0.21 mg/L. The similar binding affinities of dihydromorphine and morphine to mu-opioid receptors suggest similar pharmacological effects and adverse reactions. The determination of the pharmacologically active metabolites should help to clarify the cause of death in fatal cases especially if a relatively low concentration of the parent drug is found.
