mood stabilizer
A class of psychiatric medications used to treat bipolar disorder and other mood disorders by reducing mood fluctuations.
Full Definition
Mood stabilizers are a diverse group of medications primarily used to treat bipolar disorder by reducing the frequency and severity of manic and depressive episodes. The category includes lithium, anticonvulsants such as valproate and lamotrigine, and some atypical antipsychotics. These medications work through various mechanisms to stabilize mood and prevent mood cycling. Lithium, the prototype mood stabilizer, requires regular blood monitoring due to its narrow therapeutic window and potential for toxicity. Mood stabilizers may also be used as adjunctive treatment in unipolar depression and other psychiatric conditions.
