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 is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the human brain and body, as well as elsewhere in biology.Its name derives from its chemical structure: it is an amine formed by removing a carboxyl group from a molecule of L-DOPA.In the brain, dopamine functions as a neurotransmitter âa chemical released by nerve cells to send signals to other nerve cells.-DOPA, the metabolic precursor of dopamine, does reach the brain and is the most widely used treatment for Parkinson's disease. Dopaminergic stimulants can be addictive in high doses, but some are used at lower doses to treat ADHD.
