Title: New Treatment Approaches
1- Section 3
- New Treatment Approaches
2Treating Acute Bipolar Depression
- Great need still exists for evidence-based
approaches to this common clinical problem - Limited data support traditional antidepressants
as monotherapy - Positive data in clinical trials for OFC and
quetiapine - Clinicians need effectiveness trials to explore
the common practice of polypharmacy for acute
bipolar depression
3Evidence Based Therapies
- Impact relapse and rehospitalization rates
- Group psychoeducation
- 25 hospitalized vs 35 in unstructured group1
- Cognitive behavioral therapy (CBT)
- 1 year relapse 44 vs 75 usual care2
- Family focused treatment (FFT)
- 2 year relapse 28 with FFT vs 60 unsupportive3
- Perceived criticism may be an indicator4

- RCT, IPSRT vs ICM, n 175 BP1, 2 years
- Effect size of .58
- After controlling marital status, index polarity,
anxiety, medical burden - Mediated by improved social rhythms
- Not adherence
- Better if married
- Best initiated in early maintenance
- ICM better if medically ill and anxious
- Intensive clinical management

21BOLDER II Study
- Quetiapine monotherapy (300 mg and 600 mg)
demonstrated significant improvement from
baseline compared to placebo as early as Week 1
in all depression efficacy measures (MADRS and
HAM-D) - Significant improvements were seen in patients
with bipolar I and bipolar II disorder and in
patients with and without a rapid cycling disease
course - Improvements were seen in a broad range of
depressive symptoms - There were no major differences between the
quetiapine dose groups - Safety and tolerability findings were similar to
BOLDER I - Most common adverse events reported were dry
mouth, sedation, somnolence, dizziness, and
constipation - Incidence of treatment-emergent mania was
comparable to placebo

24Bipolar Depression and Antidepressants General
Guidelines and Risks
?
- Always use mood stabilizer in bipolar I patients,
even while depressed - Promptly wean the antidepressant if evidence of
hypomania or mania emerges - Antidepressants may trigger mania (mood
destabilization) or accelerate mood cycle - Up to 33 of patients with bipolar disorder may
be susceptible to antidepressant-induced manias - Possibly less efficacious in BP than UP
depression - Few standard antidepressants have been studied in
bipolar depression

- Maintenance
- Continue effective acute phase treatment(s) or
- Switch to one with evidence of maintenance
- efficacy
- Varies by polarity of most recent episode
- Simplify medication regimen
- Improve tolerability and adherence
- Little data on combinations in maintenance

45Summary
- Evidence-based treatment for bipolar depression
includes lithium and lamotrigine - Quetiapine and OFC are emerging as viable
alternatives for bipolar depression - Monotherapy standard antidepressants may cause
problems in terms of mood destabilization in
bipolar depression - Using antidepressants in bipolar depression is
better than nothing, but not better than using
lithium or a mood stabilizer - Some novel antipsychotics may have a role in
treating bipolar depression as monotherapy while
stabilizing mania - Goal is to stabilize depression without causing
mania and minimizing side effects
