What does dopamine antagonist do?

Dopamine antagonists are medications that block dopamine receptors in the brain, reducing the effects of dopamine, a neurotransmitter associated with pleasure and reward. These drugs are commonly used to treat conditions like schizophrenia, Bipolar disorder, and severe nausea, as they can help alleviate symptoms like hallucinations or manic episodes. By inhibiting dopamine activity, they can also help prevent the side effects of excessive dopamine, such as those seen in certain movement disorders.
