The most commonly used psychotropic medication for the treatment of bipolar disorder is c. lithium.
Lithium is a mood stabilizer that helps to control the extreme highs and lows associated with bipolar disorder. It is often prescribed alongside other medications or as a standalone treatment. While other psychotropic medications like anticonvulsants and antipsychotics may also be used in the treatment of bipolar disorder, lithium is considered the first-line treatment.
For example, anticonvulsants like valproate and lamotrigine may be used as an alternative or adjunct to lithium in certain cases. Antipsychotics such as olanzapine and quetiapine may be prescribed for acute manic episodes in bipolar disorder.
