Dopamine, mACh receptor
Substituted benzamides have been shown to possess a number of pharmacological properties most of which are related to their ability to antagonize the central and peripheral effects of dopamine and/or facilitate the release of acetylcholine on to muscarinic receptors in the gastrointestinal smooth muscle. This has led to their successful clinical use as antiemetic and in the treatment of a wide range of gastrointestinal disorders of somatic, psychosomatic and iatrogenic origin.
