Uses for Asenapine
Schizophrenia
Acute and maintenance treatment of schizophrenia in adults.
American Psychiatric Association (APA) considers most atypical antipsychotic agents first-line drugs for management of the acute phase of schizophrenia (including first psychotic episodes).
Patients who do not respond to or tolerate one drug may be successfully treated with an agent from a different class or with a different adverse effect profile.
Bipolar Disorder
Acute treatment as monotherapy or adjunctive therapy with lithium or valproate of manic or mixed episodes associated with bipolar I disorder (with or without psychotic features).
Maintenance treatment as monotherapy of bipolar I disorder.
