The mechanism of action of asenapine is not fully understood. However, based on its receptor pharmacology, it is proposed that the efficacy of asenapine is mediated through a combination of antagonist activity at D2 and 5-HT2A receptors. Actions at other receptors e.g. 5-HT1A, 5-HT1B, 5-HT2C, 5-HT6, 5-HT7, D3, and a2-adrenergic receptors, may also contribute to the clinical effects of asenapine.
