Used primarily in scientific research as a selective 5-HT1B and 5-HT1D receptor antagonist. It helps investigate the role of these serotonin receptors in neurological pathways, particularly in studies related to migraine, depression, and anxiety. Commonly applied in in vitro and in vivo models to block receptor activity and assess changes in neurotransmission. Also utilized in pharmacological studies to understand receptor function and drug interactions within the central nervous system.
