Tiapride has a high degree of regional selectivity for limbic areas. One study found that tiapride shows over three times as much affinity for limbic areas than striatal areas as opposed to the near equal selectivity for limbic and striatal regions shown by haloperidol. Another study in rats found tiapride's affinity for the septum, a limbic region, to be over thirty times as high as for the striatum. Efficacy at the D2 receptor is moderate, with 80 percent of receptors occupied even in the presence of excess tiapride concentrations.

Tiapride is a selective dopamine D2 and D3 receptor antagonist, offering an advantage over other neuroleptic drugs, such as haloperidol and risperidone, which bind a range of targets including four of the five known dopamine receptor subtypes (D1-4), serotonin (5-HT2A, 2C), α1- and α2-adrenergic, and histamine H1 receptors. Compared to these drugs, tiapride has a relatively moderate affinity for its target receptors, displacing 50 percent of 3H-raclopride binding at a concentration of 320 nM at D2 receptors and a concentration of 180 nM at D3 receptors.

Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
