Most of the older antipsychotic drugs such as chlorpromazine and haloperidol are antagonists for the dopamine D2 receptor, but are, in general, very unselective, at best selective only for the "D2-like family" receptors and so binding to D2, D3 and D4, and often also to many other receptors such as those for serotonin and histamine, resulting in a range of side-effects and making them poor agents for scientific research. In similar manner, older dopamine agonists used for Parkinson's d… WebMar 21, 2011 · Recently, timed-release bromocriptine (Cycloset), a sympatholytic dopamine D 2 receptor agonist, has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of type 2 diabetes.
