Dopamine is a neurotransmitter that helps control the brain's reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them. Dopamine deficiency results in Parkinson's Disease, and people with low dopamine activity may be more prone to addiction.

A dopamine antagonist is a chemical, medication or drug that prevents the actions stimulated by dopamine. Dopamine is a naturally produced chemical in the body that binds to regions in the brain to help regulate emotions and movement. Dopamine antagonists disrupt the activity of dopamine by blocking dopamine binding sites without activating them. These medications are used to treat a variety of disorders.
