Lorglumide sodium salt is primarily used in research settings to study the role of cholecystokinin (CCK) receptors in the body. It acts as a selective antagonist for CCK-A receptors, making it a valuable tool in understanding gastrointestinal and central nervous system functions. Researchers utilize it to investigate appetite regulation, digestion, and pancreatic secretion processes. Additionally, it has been explored in studies related to anxiety and pain management, as CCK receptors are implicated in these pathways. Its application in preclinical studies helps in developing potential therapeutic strategies for conditions like obesity, gastrointestinal disorders, and neurological diseases.
