The Role of CGRP Monoclonal Antibodies in the Treatment of Acute Cluster Headache

This article discusses the role of Calcitonin Gene-Related Peptide antagonists available on the market in treating cluster headaches. All the treatments discussed in this article focus on either abortive, preventive, or transitional care. These therapies include Monoclonal Antibodies (Galcanezumab, Fremanezumab, Erenumab), high-flow oxygen, triptans (sumatriptan, zolmitriptan), Octreotide, non-invasive vagus nerve stimulation (vagus and sphenopalatine nerves), and other medications like dihydroergotamine, lidocaine, and capsaicin. We reviewed many studies from The United States since 2015; analytical methods were utilized. Moreover, we found that some of the treatment options for CH can vary depending on efficacy and route of administration and according to categories of therapy (acute or preventive). Every treatment has a specific and unique mechanism of action, indications, contraindications, and side effects. Therefore, the recommendation of one particular treatment should be considered in the success of the treatment of Cluster Headaches. Monoclonal Antibodies against CGRP have a unique role and are considered a first alternative in treating acute CH.
