Devazepide (L-364,718, MK-329) is benzodiazepine drug, but with quite different actions from most benzodiazepines, lacking affinity for GABA<sub>A</sub> receptors and instead acting as an CCK<sub>A</sub> receptor antagonist. It increases appetite and accelerates gastric emptying, and has been suggested as a potential treatment for a variety of gastrointestinal problems including dyspepsia, gastroparesis and gastric reflux. It is also widely used in scientific research into the CCK<sub>A</sub> receptor.
Devazepide is synthesised in a similar manner to other benzodiazepines.
