Oxazepam for the Treatment of Substance Abuse and Depression: Is it Appropriate?

Distinguishing itself from other benzodiazepine drugs, oxazepam has an interesting pharmacological and clinical profile, including binding effects on the translocator protein (TSPO) and a relatively favorable safety and abuse liability profile. TSPO is found in the brain (where it is involved in neurosteroid synthesis), but is also expressed in the heart and other peripheral tissues. Oxazepam is potentially useful in the treatment of substance abuse, especially in conjunction with the cortisol synthesis inhibitor metyrapone, and can be considered an appropriate medication to use in the treatment of depression. The oxazepam/metyrapone combination has been piloted in cocaine-dependent patients and should be investigated in patients with depression. Expression of cardiac TSPO is altered by different stress conditions, and drugs binding to TSPO may have cardioprotective effects. The possibility of oxazepam, alone or together with antidepressant drugs, having a positive effect on cardiac function in patients with depression should also be studied.
