β-Calcitonin Gene-Related Peptide (CGRP) is primarily used in medical research and therapeutic applications due to its role in vasodilation and pain modulation. It is extensively studied for its potential in treating migraine headaches, as elevated levels of CGRP are associated with migraine attacks. Pharmaceutical developments have focused on CGRP antagonists and monoclonal antibodies targeting the CGRP pathway to prevent or alleviate migraines. Additionally, it is being explored for its effects in cardiovascular conditions, such as hypertension and heart failure, due to its ability to relax blood vessels and improve blood flow. Research also investigates its role in neuroprotection and inflammation, suggesting potential applications in neurological disorders and tissue repair.
