Mood stabilisers • At least: • A treatment that is effective in augmenting the management of mania and/or depression without causing switching into the opposite pole • Not toxic • Ideally: • Effective in preventing both mania and depression • Useful in both the acute situation and in relapse prevention • Well tolerated to increase compliance
Olanzapine 1 • Has a bipolar license • Strongly anti-manic • Found to have mood elevating effects • Less potent than SSRI’s1, though Olanzapine plus fluoxetine demonstrated superior efficacy for treating resistant depression compared to either agent alone • Shelton RC et al. Am J Psych 158: 131-134
Olanzapine 2 • Further studies (open label, retrospective case note reviews and case reports) show the benefit of olanzapine in the treatment of depression1,2,3,4,5,6, both as monotherapy and in combination with SSRI’s • Conflicting evidence regarding metabolic effects: • Weight gain • Abnormal glucose metabolism • Raised cholesterol levels • Dube S et al.

Lamotrigine (1) • Inhibition of Na channels, inhibit glutamate release • Clear evidence for efficacy in bipolar depression1 (licensed in 24 countries) • Studies underway suggestive of and seeking clarity for benefit in rapid cycling bipolar disorder1. Less evidence for efficacy in mania • Open studies & anecdotal reports of benefit in unipolar and treatment resistant depression2 • No risk of manic switching (highest with tricyclics) – a true mood stabiliser3 • Caution with dose escalation – rash • Macdonald KJ & Young LT.

Lamotigine – Depressive Episode1 • Calabrese et al 2002
Olanzapine • Therapeutic indications • Olanzapine is indicated for treatment of moderate to severe manic episode1 • In patients whose manic episode has responded to olanzapine treatment, olanzapine is indicated for the prevention of recurrence in patients with bipolar disorder1 • If a new manic, mixed, or depressive episode occurs, olanzapine treatment should be continued (with dose optimisation as needed), with supplementary therapy to treat mood symptoms, as clinically indicated 1.
