Dopamine receptor D2, also known as D2R, is a protein that, in humans, is encoded by the DRD2 gene.n similar manner, older dopamine agonists used for Parkinson's disease such as bromocriptine and cabergoline are poorly selective for one dopamine receptor over another, and, although most of these agents do act as D 2 agonists, they affect other subtypes as well.
Antagonists of the 5-HT2A receptor are sometimes used as atypical antipsychotics (contrast with typical antipsychotics, which are purely dopamine antagonists). They include: 1  Cyproheptadine blocks 5-HT 2A, H1 and is a mild anticholinergic. 2  Methysergide is a 5-HT 2A antagonist and nonselective 5-HT1 receptor blocker.
