The open-label study included 10 women who had failed to respond adequately to treatment with antidepressant. Aripiprazole was added to the antidepressant at 2 mg/day at the second visit and increased weekly in 1- to 2-mg increments as needed to a maximum of 10 mg/day.
Eight of ten women completed the trial. Six of the women (75%) experienced remission, defined as a MADRS score of less than 10. Seven of the women (88 %) showed a positive response, defined as having 50% or greater reduction in MADRS score. Aripiprazole was well tolerated; patients reported mild side effects such as sleeplessness (n=3), headaches (n=2), and nausea (n=2). There were no switches to hypomania or mania during treatment with aripiprazole. All participants remaining in the study at week 8 were receiving a dose of 2 mg aripiprazole at their final visit.
While this is a very small study and needs to be replicated in a larger sample, the results are promising. The response and remission rates observed in this study were higher than those observed in open-label studies of antidepressants for PPD. In addition, the women responded to low doses of aripiprazole and experienced no serious side effects.
