Dopamine blockers and depletors are used to treat conditions that arise from the over-production or increased activity of dopamine. Dopamine blockers work by binding to and blocking the action of dopamine receptors.his prevents the receptors from using the dopamine that is present in the brain or elsewhere in the body. Conversely, dopamine depletors work by preventing dopamine from being stored or released by neurons. There are numerous types of dopamine blockers and depletors.
Dopamine production. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area. It is a neurohormone that is released by the hypothalamus.opamine is also used as medication. It acts on the sympathetic nervous system. Application of dopamine leads to increased heart rate and blood pressure. Dopamine cannot cross the blood-brain barrier, so dopamine given as a drug does not directly affect the central nervous system.
