Lurasidone is already approved for Bipolar Depression as Monotherapy and is Indicated as monotherapy for adults with major depressive episode associated with bipolar I disorder (bipolar depression).It is given in 20 mg per day initially; may increase the dose if needed, not to exceed 120 mg/day.However, in monotherapy study, higher dose range (80-120 mg/day) did not provide additional efficacy compared to the lower dose range (20-60 mg/day).
Lurasidone is an atypical antipsychotic indicated for the treatment of:
- Schizophrenia in adults and adolescents (13 to 17 years)
- Depressive episode associated with Bipolar I Disorder (bipolar depression) in adults and pediatric patients (10 to 17 years) as monotherapy
- Depressive episode associated with Bipolar I Disorder (bipolar depression) in adults as adjunctive therapy with lithium or valproate
