Les avancees dans les traitements de crise et de fond de la maladie migraineuse

摘要

The current treatment of migraine attacks is triptans and NSAIDs, but the calcitonin gene-related peptide (CGRP) has emerged as a key neuropeptide target for migraine therapy. Despite an off target class effect on liver enzymes, two CGRP receptor antagonists, ubrogepant and rimegepant, remain in development, together with a 5-HT_1F receptor agonist (lasmiditan), for which cardiovascular contraindications that limit the utility of triptans do not exist. Importantly, to avoid an excessive use of acute medication with the risk of medication overuse, prophylactic therapeutics are the best choice. To date, monoclonal antibodies which block CGRP actions are on the market all over the world but not yet in France. The research is very active in different directions and targets notably hypothalamic neuropeptides because the hypothalamus hosts many key neuropeptide systems that seem to play a role in migraine physiopathology. These neuropeptides include orexins, oxytocin, neuropeptide Y (NPY) and pituitary adenylate cyclase-activating polypeptide (PACAP). In addition, other promising drugs for the treatment of migraine are nitric oxide synthase inhibitors and acid-sensing ion channel (ASIC) blockers.
