Used primarily in scientific research as a selective antagonist for 5-HT4 receptors, aiding in the study of serotonin signaling pathways in the gastrointestinal tract and central nervous system. Its ability to block specific serotonin receptors makes it valuable in investigating gastrointestinal motility, cardiac function, and potential cognitive effects linked to serotonergic activity. Due to its research-focused profile, it is not used clinically but supports pharmacological studies aiming to understand receptor-specific effects and develop new therapeutic agents.
