General description

Asenapine maleate acts as an antimanic. It belongs to the family of dibenzoxepinopyrrolidines. Asenapine is considered to be a weak inhibitor of cytochrome P450 2D6 (CYP2D6). It increases the level of dopamine, norepinephrine and acetylcholine in brain.

Application

Asenapine maleate has been used as a stressor in studying the Fos expression in forebrain structures of rat models.
Asenapine maleate is a serotonin 5-HT and dopamine D2 receptor antagonist. Asenapine maleate can be used to treat schizophrenia and bipolar mania.

Biochem/physiol Actions

Asenapine maleate is a 5-HT receptor antagonist (5-HT1A,1B, 5-HT2A, 2B, 2C, 5-HT5A, 5-HT6 and 5-HT7), a D2 antagonist, and an antipsychotic.
