Haloperidol works primarily by blocking dopamine receptors in the brain. Dopamine is a neurotransmitter that influences mood, perception, and movement. Excess dopamine activity is associated with psychosis and other psychiatric disorders. By interfering with dopamine transmission, haloperidol can reduce psychotic symptoms, improve thinking and behavior, and provide a calming effect.
