Tarazepide is primarily used in medical research and therapeutic applications due to its pharmacological properties. It functions as a cholecystokinin (CCK) receptor antagonist, which makes it valuable in studying gastrointestinal and central nervous system disorders. Researchers utilize it to explore its potential in managing conditions like anxiety, panic disorders, and appetite regulation. Additionally, its role in modulating CCK activity has implications for understanding and treating digestive issues, such as irritable bowel syndrome (IBS) and other motility-related disorders. Its application extends to experimental studies aimed at developing targeted therapies for neurological and gastrointestinal diseases.
