How Haloperidol works
Haloperidol is a first-generation antipsychotic medication.
It works by blocking the action of dopamine, a neurotransmitter in the brain that affects thoughts, feelings and behaviour. By inhibiting the excess activity of dopamine in certain parts of the brain, Haloperidol can help to manage the symptoms of psychosis, such as hallucinations, delusions, and disordered thinking associated with conditions like schizophrenia.
