Revisiting the effectiveness of standard antidepressants in bipolar disorder: are monoamine oxidase inhibitors superior?
Abstract
Objective: The role of antidepressants in treating bipolar disorder is controversial, and the comparative effectiveness of specific drugs is insufficiently studied.We report here a comparison of monoamine oxidase inhibitors (MAOIs) with the serotonin reuptake inhibitor paroxetine (PAROX).
Experimental design: We conducted a retrospective analysis of data from a larger study, using the first antidepressant trial administered either after entry (n = 46) or after a recurrent episode during study participation (n = 6).Twenty two patients were treated with PAROX and 30 with an MAOI. Durable recovery was determined from Hamilton depression and Young mania scores, based on published criteria.
Principal observations: PAROX treatment led to durable recovery in 27% of patients, a result very similar to the 24% recovery rate found in a recent STEP-BD trial. In contrast, patients treated with an MAOI had a 53% durable recovery rate. Survival analysis showed a significantly faster onset of durable recovery with MAOIs (x2 = 4.77, p = 0.029). Among subjects who were able to complete an adequate treatment trial of at least four weeks duration, durable recovery was attained in a significantly greater proportion of those treated with an MAOI (16 of 23, 70%) as compared to PAROX (6 of 18, 33%)(Fisher's Exact Test, p = 0.023).
Conclusions: In these patients with bipolar depression, the antidepressant effectiveness of PAROX was unacceptably low, but rates of recovery with MAOIs were significantly higher.
