Alprazolam: an antidepressant? Alprazolam, desipramine, and an alprazolam-desipramine combination in the treatment of adult depressed outpatients.
The antidepressant efficacy of alprazolam (ALP) was tested in a double-blind controlled comparison with desipramine (DMI) and an ALP-DMI combination in outpatients diagnosed with major depressive disorder by Research Diagnostic Criteria (90% met criteria for endogenous subtype). Following a placebo period of at least 1 week, subjects who continued to meet severity criteria defined by Hamilton Depression Rating Scale (HDRS) scores were administered oral doses of the active medication (N = 79), in a dose ratio of 1 mg ALP:50 mg DMI:1 mg ALP + 50 mg DMI. Treatment continued for 6 weeks, and all subjects who completed at least 2 weeks (N = 69) were included in endpoint analyses. Following the placebo baseline, symptoms were rated again at day 5 and at the end of weeks 1, 2, 4, and 6. Final doses averaged 4.6 +/- 1.3 mg for the ALP group, 230 +/- 61 mg for the DMI group, and 4.6 +/- 1.2 mg ALP + 229.5 +/- 1.2 mg DMI for the combination group. The final outcome was a comparable degree of improvement at the endpoint among the three treatment groups on measures of depression (HDRS and Beck Depression Inventory), anxiety (Hamilton Anxiety Rating Scale), and global improvement (Global Assessment Scale, and Physician and Patient Global Impressions). A similar outcome was found for the subgroup of patients who completed all 6 weeks (N = 56). Endpoint analyses also showed that ALP-treated subjects responded sooner and continued to show improvement throughout the course of the study on measures of depression, anxiety, and global status. These results suggest that ALP alone is as effective as a standard tricyclic for the acute treatment of patients with major depressive disorder and that significant improvement may occur within the first week of medication. Side effect profiles were compared among treatment groups and are discussed, as are other clinical studies that have investigated ALP's potential antidepressant efficacy.
