Carpipramine (Defekton) is an antipsychotic agent that belongs to the iminodibenzyl class. Carpipramine is a potent dopamine antagonist which blocks alpha 1- and alpha 2-adrenoceptors. Carpipramine also has antagonist properties with respect to serotonin (5-HT2) receptors. Carpipramine exhibits antipsychotic and anti-depressant effects. Carpipramine can be used for the research of neurological disease, such as post-traumatic stress disorder (PTSD) and depression[1].
