Results of a previous study indicated that the opioid effects of methadone were enhanced by the concurrent administration of diazepam in methadone-maintained subjects. To determine whether a pharmacokinetic interaction might account for this methadone-diazepam interaction, the plasma levels of methadone, diazepam and diazepam metabolites were determined in blood samples collected during that study. Five adult male patients on methadone maintenance (50-60 mg/day) were administrated single doses of placebo, diazepam (20 and 40 mg), methadone (100%, 150% and 200% of the maintenance dose), and four diazepam-methadone dose combinations (20 and 40 mg diazepam in combination with 100% and 150% of the maintenance dose). The results showed that the concurrent administration of methadone and diazepam did not significantly change the time-course or areas under the plasma concentration-time curve of methadone, diazepam or N-desmethyl-diazepam compared to the levels following the administration of either drug alone. Thus, plasma drug level analysis does not indicate a pharmacokinetic interaction between diazepam and methadone.

Plasma level of diazepam as a therapeutic predictor in anxiety states

An oral test dose of diazepam was given to 25 anxious neurotics before they received three weeks of treatment with the drug. Blood was taken at 1 h and 2 h.

An oral test dose of diazepam was given to 25 anxious neurotics before they received three weeks of treatment with the drug. Blood was taken at 1 h and 2 h after the test dose (and during subsequent treatment) and the plasma levels of diazepam at these times were assayed. Ratings to assess subsequent clinical response were made in the context of a double-blind trial.

The 1 h plasma diazepam level, in contradistinction, had but negligible correlations with steady-state levels, with clinical response and with diazepam-induced tiredness.

A high 2 h plasma level was found in those patients who reported increased tiredness during the three weeks on diazepam.

The 2 h plasma level correlated positively with the steady-state plasma level of diazepam after one week of treatment.

There was a statistically strong link between a low 2 h plasma diazepam level and improvement after the first week of treatment. This correlation of low pretreatment plasma level with good response suggests either that there may be an avid uptake of diazepam from the blood in those who are going to improve clinically as a result of its administration, or that good responders have a special ability to form active metabolites of diazepam.
