These antagonists can block dopamine receptors and can help with addiction to drugs and alcohol. But the prize goes to the D2 receptor. Dopamine (DA) is one of the major neurotransmitters and participates in a number of functions such as motor coordination, emotions, memory, reward mechanism, neuroendocrine regulation etc. In Jul 3, 2015 · Most antipsychotics primarily function by acting as dopamine receptor (D2) antagonists. It will up-regulate dopamine and increase receptor density. This means they bind to the dopamine receptors and prevent stimulation from misfiring or abnormally high dopamine concentrations. DA exerts its effects through five DA receptors that are subdivided in 2 families: D1-like DA receptors (D 1 and D 5) and the D2-like (D 2, D 3 and D 4). This amount of dopamine is higher than what is endogenously (inside the body) produced. While the dopamine neural pathway may be a final common route to many of the clinical symptoms, the components of this pathway, such as Dopamine receptor expression changes in TBI.
