Understanding the efficacy and tolerability of migraine treatment: a deep dive into CGRP antagonists.

Introduction: The discovery of the role of the calcitonin gene-related peptide (CGPR) in migraine pathogenesis ushered in a new era in headache medicine. This evidence led to the development of small-molecule CGRP receptor antagonists and monoclonal antibodies targeting either CGRP or its receptor.

Areas covered: We will present selected aspects of the role of CGRP in the pathogenesis of migraine, the efficacy of CGRP-targeted treatment, and the still-open questions regarding the practical application of CGRP antagonists in headache medicine.

Expert opinion: CGRP-targeting drugs represent a transformative approach to migraine treatment, offering superior efficacy and tolerability compared to traditional therapies, they are a helpful addition to the treatment arsenal but also have their flaws and require further observation. Their availability provides new hope for migraine patients, particularly those who have not responded adequately to conventional treatments. Future directions for migraine care planning, especially for chronic migraine and medication-overuse headache, should include universal access to these specific and effective forms of therapy to prevent complications from the disease and its negative effects in many aspects of a patient's life.
