One subject withdrew before week 2 due to flu-like
symptoms with no follow-up ratings. Three patients
discontinued their treatment before week 4 and a further
three before week 8 due to akathisia (1), agitation and
anxiety (1), mild hypomanic symptoms (2) and inadequate
efficacy (2). There were no significant differences
in SAS, BAS or AIMS scores from baseline to week 8
either for the whole group or for the bipolar II group
only. Nine patients continued with aripiprazole following
the acute study. Two patients discontinued within the
first 2 months due to relapse, five maintained their improvement
for 6 months, and a further two patients continued
for 11 to 12 months.
