What is Haloperidol Decanoate
HaloperidolThe Generic name of this drug
Treatment SummaryHaloperidol is a medication used to treat symptoms of mental disorders such as schizophrenia, Tourette syndrome, and severe behavioural states. It works by blocking dopamine receptors in the brain, reducing the overproduction of dopamine associated with these disorders. Haloperidol is usually effective and well-tolerated, although it can cause side effects such as movement disorders, sedation, weight gain, and prolactin changes. It is less likely to cause these side effects than other first-generation antipsychotic drugs, such as chlorpromazine and thioridazine. While haloperidol is still widely used, it has been

Effectiveness
How Haloperidol Decanoate Affects PatientsHaloperidol is an antipsychotic medication that is used to treat the positive symptoms of schizophrenia, such as hallucinations, aggression, disorganized speech, and psychomotor agitation. It can cause side effects such as movement disorders, sedation, weight gain, and changes in prolactin levels. Compared to other first-generation antipsychotics, haloperidol usually has fewer side effects. However, it can still cause serious health issues including QT-prolongation and torsade de pointes (heart rhythm issues), Neuroleptic Malignant Syndrome (NMS), and a syndrome with potentially irreversible involuntary movement disorders
How Haloperidol Decanoate works in the bodyHaloperidol works by blocking dopamine receptors in the brain, which helps reduce symptoms of psychosis. The drug binds tightly to dopamine D2 receptors, which can lead to the development of side effects like extrapyramidal symptoms. Haloperidol has some effect on other receptors, including 5-HT2 and alpha-1 receptors, and it also works on the chemoreceptive trigger zone to provide antiemetic effects. Newer medications have been developed that work in a similar way but have a lower affinity for dopamine D2 receptors, which decreases the risk of extrapyramidal symptoms. Haloperidol should only be used
