Evidence-based symptomatic treatment of migraine.

Symptomatic treatment of migraine includes patient education, mainly to avoid medication overuse and known trigger factors, as well as pharmaceutical and nonpharmaceutical interventions. Disease-specific and mechanism-based agents include ergotamine and dihydroergotamine targeting the adrenergic, dopaminergic, and serotoninergic systems followed by triptans, specific agonists for 5-HT1B/1D/1F receptors, the latest being more favorable in terms of safety and documentation of efficacy. Recently, antagonists of calcitonin gene-related peptide (gepants) and selective agonists of the 5-HT1F receptor (ditans) have been added, with promising efficacy and safety. Triptans stay as the first option treatment when attacks are moderate to severe, followed by nonspecific agents, including aspirin and paracetamol/acetaminophen and nonsteroidal antiinflammatory drugs (NSAIDs, ibuprofen and naproxen share the best documentation) for mild-to-moderate migraine attacks. Combinations with caffeine are effective as well, but barbiturates and opioids alone or in combinations should be avoided. Simple analgesics and NSAIDs attenuate cephalic pain via prostaglandin mediated mechanisms and may induce peptic, renal and hepatic adverse effects. Neuromodulation techniques include single-pulse transcranial magnetic stimulation (s-TMS), external trigeminal nerve stimulation (e-TNS), remote electrical neuromodulation (REN) and noninvasive vagus nerve stimulation (nVNS). All share good documentation and safety profile and are worthy of alternative treatment options along with physical therapy when medicines are contradicted or not well tolerated or unwanted by the patients.
