Tiapride hydrochloride is a selective dopamine D2 and D3 receptor antagonist primarily used in the treatment of psychiatric and neurological disorders. It is effective in managing symptoms of anxiety, agitation, and behavioral disturbances, particularly in elderly patients with dementia or Parkinson's disease. Additionally, it is prescribed for conditions such as Tourette syndrome and chorea, where it helps reduce involuntary movements and tics. The compound is also utilized in alcohol withdrawal therapy to alleviate symptoms like restlessness and tremors. Its application extends to pediatric psychiatry for treating hyperactivity and aggression in children. By adjusting the balance of neurotransmitters in the brain, it plays a significant role in improving the quality of life for patients with these conditions.
