Use | Acenapine maleate is a drug suitable for the treatment of schizophrenia, suitable for the acute treatment of bipolar disorder type I mania or mixed episodes. |
In vitro study | Asenapine shows high affinity and differential rank order (pKi) for serotonin receptor binding affinity (5-HT1A[8.6],5-HT1B[8.4],5-HT 2A[10.2],5-HT 2B[9.8],5-HT 2C[10.5],5-HT5[8.8],5-HT 6[9.6] and 5-HT 7[9.9]), adrenergic receptor (α1[8.9],alpha2A[8.9],alpha2B[9.5] and alpha2C[8.9]), dopamine receptors (D1[8.9],D2[8.9],D3 [9.4] and D4[9.0]) and histamine receptors (H1 [9.0] and H2[8.2]). Asenapine has higher affinity with 5-HT 2C,5-HT 2A,5-HT 2B,5-HT 7,5-HT 6,alpha2B and D3 receptors, indicating that these target molecules are involved in therapy. Asenapine appears to be a potent antagonist (pKB),5-HT 1A(7.4),5-HT1B(8.1),5-HT 2A(9.0),5-HT 2B(9.3),5-HT 2C(9.0),5-HT 6(8.0 ),5-HT 7(8.5),D 2(9.1),D3(9.1),alpha2A(7.3),alpha2B(8.3),alpha2C(6.8) and H 1 receptor (8.4). |
In vivo study | In free-moving rats, Asenapine(0.05-0.2 mg/kg, S.C.) induced dose-dependent CAR inhibition (no escape failure recording) and did not induce catalepsy. In rats, Asenapine(0.05-0.2 mg/kg, S.C.) simultaneously increased dopamine efflux in the medial prefrontal cortex (mPFC) and nucleus accumbens. Asenapine(0.01 mg/kg, iv) increased dopamine efflux preferentially compared to volt-septum core, whereas at higher doses (0.05 mg/kg, I. v.), the difference disappeared. In pyramidal cells of the medial prefrontal cortex, Asenapine significantly enhanced NMDA-induced responses. |
