Tiapride is a dopamine D2 and D3 receptor antagonist indicated in the treatment of chorea in Huntington's disease, as well as agitation and anxiety in the elderly or with acute or chronic alcoholism.
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.
Tiapride is indicated for the treatment of a variety of neurological and psychiatric disorders including dyskinesia, alcohol withdrawal syndrome, negative symptoms of psychosis, and agitation and aggression in the elderly.
