These specialized medications work by targeting the calcitonin gene-related peptide (CGRP), a neuropeptide that plays a crucial role in the pathophysiology of migraine headaches作者：A Nekomoto·2023·被引用次数：22—This study aimed to examine the feasibility ofrimegepant administration, a CGRP receptor antagonist already used in clinical practice for .... By blocking the action of CGRP at its receptors, these antagonists offer a novel approach to alleviating migraine pain and reducing the frequency of attacks.

CGRP is a small protein that is highly prevalent in the sensory nervous system. During a migraine, CGRP is released and is believed to contribute to vasodilation and neurogenic inflammation in the cranial blood vessels, leading to the characteristic pain. CGRP receptor antagonists, commonly referred to as gepants, are the first class of migraine-specific medications that do not have vasoconstrictive action, a common side effect of older migraine treatments. This distinction is crucial, as it avoids potential cardiovascular concerns associated with narrowing blood vessels.Ubrogepant (MK-1602) is an orally active and selective antagonist of calcitonin gene-related peptide receptor (CGRP).

The development of CGRP receptor antagonists has led to the creation of both acute and preventive treatments. For acute migraine attacks, these medications can provide rapid relief. For preventive purposes, they can significantly reduce the number of migraine days experienced by individuals. The effectiveness of CGRP receptor antagonists in treating migraine attacks has been well-documented, with some studies indicating they are effective at aborting acute migraine attacks.

Several specific CGRP receptor antagonists have emerged as important therapeutic options. Ubrogepant (MK-1602) is an example of an orally active and selective antagonist of the CGRP receptorCalcitonin gene-related peptide receptor antagonists. Similarly, rimegepant is another significant gepant that has been studied for its efficacy. Both ubrogepant, rimegepant, and atogepant are now available for treating acute episodes and are delivered orally作者：A Rashid·2023·被引用次数：22—CGRP receptor antagonists ("gepants") are the first class of migraine-specific medication that does not have vasoconstrictive action, shows .... The feasibility of rimegepant administration for migraine management has been a subject of ongoing research.

Beyond small molecule gepants, antibody-based therapies have also been developed.Calcitonin Gene Related Peptide I (8-37), human / CGRP ... While not all antibody therapies are direct CGRP receptor antagonists, some target the CGRP pathway. For instance, Galcanezumab, A calcitonin-gene related peptide antagonist, is used to prevent migraines and treat cluster headaches.Calcitonin Gene Related Peptide I (8-37), human / CGRP ... These CGRP-targeted therapies were specifically developed to address the unmet needs in migraine treatment.

The scientific exploration into CGRP and its role in migraine dates back decades. Early research identified Calcitonin Gene Related Peptide (CGRP) (8-37) as a fragment that could act as an antagonist against CGRP receptors, though not calcitonin receptors. This discovery paved the way for the development of more sophisticated calcitonin gene-related peptide receptor antagonist compounds作者：A Jamaluddin·2022·被引用次数：19—This study aimed to explore the feasibility of developinglipidated CGRP peptide antagoniststhat retain receptor antagonist activity in vitro and attenuate .... The nonpeptide CGRP-receptor antagonist BIBN 4096 BS was one of the earlier examples demonstrating efficacy in treating migraine attacks, even up to six hours after onset.

The mechanism of action for these drugs involves a competitive antagonism at the CGRP receptors. This means they bind to the receptor and prevent CGRP from activating it, thereby interrupting the cascade of events that lead to migraine pain. The development of orally available small molecule calcitonin gene-related peptide (CGRP) receptor antagonists has been a significant breakthrough, offering greater convenience for patients compared to injectable treatments.

While the focus has largely been on migraine, the understanding of CGRP's broader physiological roles is expanding. Research into AT1 receptor-neprilysin inhibition, for example, explores related pathways that might influence cardiovascular health.作者：PJ Goadsby·2008·被引用次数：42—Calcitonin gene-related peptide (CGRP) receptor antagonistBIBN4096BS is effective in the treatment of migraine attacks. N Engl J Med 2004;350:1104–1110. ... 12. However, the primary clinical application of calcitonin gene-related peptide receptor antagonist drugs remains firmly rooted in the management of migraine.

The availability of these advanced therapies has transformed the landscape for individuals suffering from chronic and debilitating migraines. They represent a targeted and effective approach, offering hope for improved quality of life and reduced pain burden. The ongoing research into CGRP receptor antagonists and related calcitonin gene-related peptide (CGRP) inhibitors promises further advancements in the field.作者：AHJ Danser·2017·被引用次数：6—OptimumAT1 receptor-neprilysin inhibitionhas superior cardioprotective effects compared with AT1 receptor blockade alone in hypertensive rats.
