Used in research to study migraine and neurogenic inflammation. Acts as a potent vasodilator, helping investigate vascular responses and sensory nerve function. Commonly applied in receptor binding assays and functional studies involving the calcitonin gene-related peptide (CGRP) receptor pathway. Valuable in developing and testing anti-migraine therapeutics, especially CGRP receptor antagonists. Also utilized in in vitro and in vivo models to explore pain transmission and neurovascular interactions.
