Pimozide is primarily used in the treatment of chronic schizophrenia and other psychotic disorders. It helps manage symptoms such as hallucinations, delusions, and disorganized thinking by blocking dopamine receptors in the brain. Additionally, it is effective in controlling motor and vocal tics in patients with Tourette syndrome, providing relief from involuntary movements and sounds. In some cases, it is also prescribed for severe behavioral problems in children, particularly those associated with hyperactivity and aggression. Due to its sedative effects, it can help reduce agitation and anxiety in certain psychiatric conditions. However, its use requires careful monitoring due to potential side effects, including extrapyramidal symptoms and cardiac issues.
