Antidepressants were superior to placebo in reducing new depressive episodes in bipolar disorders without increasing risk of new manic/hypomanic episodes either used as monotherapy or in combination with MS .
Subgroup analyses revealed that greater benefit and lower risk may be achieved in BD II than in BD I. However , compared with MS monotherapy , AD monotherapy significantly increased the risk of affective switch with no improvement in prophylaxis of new depressive episodes .
CONCLUSIONS Reduced new depressive episodes may be achieved by long-term AD treatment with no significantly increased risk of new manic/hypomanic episodes in BD , particularly in BD II .
The elevated risk of affective switch  of AD monotherapy compared with MS monotherapy may be contributed to the protective effect of MS in diminishing manic/hypomanic episodes .
OBJECTIVE Efficacy and safety of long-term use of antidepressants ( AD ) in bipolar disorder ( BD ) patients remains highly controversial .
Here we performed a meta- analysis of r and omized controlled trials ( RCTs ) exploring the efficacy and safety of long-term AD use in BD patients .
The Bipolar Interactive Psychoeducation (BIPED) study: trial design and protocol
Background Bipolar disorders affect between 3–5 % of the population and are associated with considerable lifelong impairment . Since much of the morbidity associated with bipolar disorder is caused by recurrent depressive symptoms , which are often only poorly responsive to antidepressants , there is a need to develop alternative , non-pharmacological interventions . Psychoeducational interventions have emerged as promising long-term therapeutic options for bipolar disorder . Methods / design The study is an exploratory , individually r and omised controlled trial . The intervention known as ' Beating Bipolar ' is a psychoeducational programme which is delivered via a novel web-based system . We will recruit 100 patients with a diagnosis of DSM-IV bipolar disorder ( including type I and type II ) currently in clinical remission . The primary outcome is quality of life . This will be compared for those patients who have participated in the psychoeducational programme with those who received treatment as usual . Quality of life will be assessed immediately following the intervention as well as 10 months after r and omisation . Secondary outcomes include current depressive and manic symptoms , number of episodes of depression and mania/hypomania experienced during the follow-up period , global functioning , functional impairment and insight . An assessment of costs and a process evaluation will also be conducted which will explore the feasibility and acceptability of the intervention as well as potential barriers to effectiveness . Discussion Bipolar disorder is common , under-recognised and often poorly managed . It is a chronic , life-long , relapsing condition which has an enormous impact on the individual and the economy . This trial will be the first to explore the effectiveness of a novel web-based psychoeducational intervention for patients with bipolar disorder which has potential to be easily rolled out to patients .Trial registration Current Controlled Trials IS RCT
