[Anti-CGRP-based Migraine Medications: A Comprehensive Overview].

Abstract

In the early 1990s, the neuropeptide calcitonin gene-related peptide (CGRP) was identified as a key messenger in the pathophysiology of migraine and emerged as a treatment target, fundamentally transforming our approach to migraine therapy. While previous prophylactic drugs were non-specific and often caused intolerable side effects, the discovery of CGRP marked the advent of a new era in migraine treatment. The two main classes of CGRP-specific migraine treatments are monoclonal antibodies that bind to CGRP or the CGRP receptor, and CGRP receptor antagonists, the so-called gepants. Extensive clinical trials have conclusively demonstrated the safety, tolerability, and efficacy of monoclonal CGRP(-receptor) antibodies in the prophylactic treatment of both episodic and chronic migraine. The same positive results apply to the use of various gepants. They have proven to be not only an effective alternative to triptans in acute migraine therapy but also promising options for continuous use as prophylactic treatments. In this review, we aim to present the current state of research on CGRP-specific migraine therapy and insights in real-world data from the first years after their launch in clinical practice.
