Tiospirone is a 5-HT2 receptor antagonist with affinity for D2, 5-HT1a, and 5-HT7, and sigma receptors. Tiospirone decreases consumption of ethanol while increasing food intake of rats. Tiospirone can also reduce the reinforcing properties of Cocaine exhibited in the conditioned place preference paradigm[1][2].
