The US Food and Drug Administration (FDA) has approved a supplemental new drug application for lurasidone (Latuda, Sunovion Pharmaceuticals Inc), a serotonin-dopamine antagonist, for the treatment of major depressive episodes associated with bipolar I disorder (bipolar depression) in children and adolescents aged 10 to 17 years.
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
