Orexigenic properties in animals.[3][4] The mechanism for increasing feed intake is not clear and has been subject of investigation.[5] It has been found that elfazepam suppresses gastric acid secretion.[6]

Synthesis

Benzophenone derivative 1 is reacted with a glycine equivalent masked as an oxazolidine-2,5-dione 2 to give the final product 3 Elfazepam.
