Potent 5-HT2 antagonist, also active as 5-HT1 antagonist. Differentiates 5-HT1D sub-types. Also displays affinity for rodent 5-HT5B, 5-HT5A, 5-HT7 and 5-HT6 receptors (pK1 values are 6.6, 7.0, 8.4 and 8.7 respectively). It has a role as a serotonergic antagonist, a dopaminergic antagonist and an antipsychotic agent. It contains a methiothepin(2+)."}]
