Background
Aripiprazole, structurally considered a third-generation antipsychotic agent, is an effective adjuvant strategy for managing treatment-resistant depression. It has been used successfully as an add-on agent in late-life depression (LLD), but there are no controlled trials on its use as first-line therapy, either alone or in combination with an antidepressant.
Methods
This is a case note review of aripiprazole prescribed to outpatients with LLD as a first-line therapy either in combination with an antidepressant or as a monotherapy. The local ethics committee approved the audit. Case notes of subjects with Hamilton Rating Scale for Depression scores of ≥11 and with at least 1 follow-up visit were included in the review. Remission was defined as the first occurrence of achieving a Hamilton Rating Scale for Depression score of <10.
Results
Case notes of 54 subjects (mean age, 68.6 ± 6.9 years) were included, 52 of whom had unipolar depression. Aripiprazole alone was prescribed in 21 subjects, and with an antidepressant in the remaining subjects. The overall remission rate was 59% over 21 weeks, and in the remitted subjects (n = 32), the cumulative remission rate increased from 22% at week 2 to 82% at week 10. No subject discontinued treatment because of poor tolerability or serious adverse events.
Conclusions
Aripiprazole was found to be an effective first-line antidepressant in LLD. The remission rates in the present study were considerably higher than the published literature on antidepressant monotherapy in fresh episodes of LLD. This warrants controlled trials of aripiprazole as a first-line antidepressant for this disease entity.
