Novel synthetic treatment options for migraine

Introduction: Migraine is one of the most common neurological disorders. Nowadays, the 5-HT1B/1D receptor agonists, namely triptans, are considered as the standard of care for migraine acute treatment. However, triptans have limitations in some patients, such as incomplete pain relief, headache recurrence, and cardiovascular contraindications. New 5-HT1F receptor agonists, namely ditans, and calcitonin gene-related peptide receptor antagonists, namely gepants, have been developed as migraine-specific treatments. Areas covered: This paper reviews the available data from RCTs to assess the clinical efficacy, safety, and tolerability profile of lasmiditan, rimegepant, and ubrogepant for the acute treatment of migraine and atogepant for the prevention of migraine. Expert opinion: Available data suggest that lasmiditan, rimegepant, and ubrogepant might not have a clinical efficacy similar to triptans. Lasmiditan did not cause the typical triptan side effects but was associated with central nervous system side effects, causing temporary driving impairment. On the contrary, the new generation of gepants showed a placebo-like tolerability profile and the absence of a specific pattern of side effects. Future studies on lasmiditan and gepants with respect to established effective comparators are mandatory to support phase III results and to help clinicians to balance the benefit/risk profiles of the various acute and preventive medications.
