Abstract
Primary headache disorders in particular migraine are one of the most common causes of disability worldwide. Given the high burden of migraine in terms of disability, there has been an effort to develop migraine specific therapies that has led to the availability of new drugs including 5HT1F receptor agonists-ditans (lasmiditan), small molecule calcitonin gene-related peptide (CGRP) receptor antagonists-gepants: (ubrogepant, rimegepant, atogepant) and anti-CGRP monoclonal antibodies (erenumab, fremanezumab, galcanezumab and eptinezumab). However, some of these treatments incur a high cost and may not be a feasible option for most patients in resource limited settings. Lasmiditan and the gepants are a good option for patients with moderate-severe migraine attacks who cannot use triptans due variously to poor tolerability, or cardio- or cerebrovascular disease. For practical purposes, the new anti-CGRP monoclonal antibodies are best reserved for patients who have failed to have efficacy or had intolerable side effects from multiple traditional oral preventives.
