Acute migraine headache attacks
A recent review in the Journal of Neuro-Ophthalmology by Konstantinos Spingos and colleagues (including me as the senior author) details typical and new treatments for migraine. We all know about the longstanding options, including the 7 triptans and ergots, as well as over-the-counter analgesics, which can be combined with caffeine, nonsteroidal anti-inflammatory drugs; and many use the 2 categories of medication that I no longer use for migraine, butalbital-containing medications, and opioids.
Now 2 gepants are available—small molecule calcitonin gene-related peptide (CGRP) receptor antagonists. These medications are thought to be a useful alternative for those in whom triptans do not work or are relatively contraindicated due to coronary and cerebrovascular problems and other cardiac risk factors like obesity, smoking, lack of exercise, high cholesterol, and diabetes. Ubrogepant was approved by the FDA in 2019, and rimegepant soon followed in 2020.
- Ubrogepant: In the ACHIEVE trials, approximately 1 in 5 participants who received the 50 mg dose were pain-free at 2 hours. Moreover, nearly 40% of individuals who received it said their worst migraine symptom was resolved at 2 hours. Pain relief at 2 hours was 59%
- Rimegepant: Like ubrogepant, about 20% of trial participants who received the 75 mg melt tablet dose of rimegepant were pain-free at 2 hours. Thirty-seven percent reported that their worst migraine symptom was gone at 2 hours. Patients began to return to normal functioning in 15 minutes.
In addition to gepants, there is 1 ditan approved, which stimulates 5-HT1F receptors. Lasmiditan is the first medication in this class to be FDA-approved. It, too, is considered an alternative in patients in whom triptans are ineffective or when patients should not take a vasoconstrictor. In the most recent phase 3 study, the percentage of individuals who received lasmiditan and were pain-free at 2 hours were 28% (50 mg), 31% (100 mg) and 39% (200 mg). Relief from the migraine sufferers’ most bothersome symptom at 2 hours occurred in 41%, 44%, and 49% of patients, respectively. Lasmiditan is a Class V controlled substance. It has 18% dizziness in clinical trials. After administration, patients should not drive for 8 hours, and it should only be used once in a 24-hour period.
Non-pharmaceutical treatment options for acute migraine include nerve stimulation using electrical and magnetic stimulation devices, and behavioral approaches such as biofeedback training and mindfulness. The Nerivio device for the upper arm is controlled by a smart phone app and seems to work as well as a triptan in some patients with almost no adverse events. Just approved in February is the Relivion device which is worn like a tiara on the head and stimulates the frontal branches of the trigeminal nerve as well as the 2 occipital nerves in the back of the head.
Acute care of cluster headache attacks
In 2011, Ashkenazi and Schwedt published a comprehensive table in Headache outlining the treatment options for acute cluster headache. More recently, a review in CNS Drugs by Brandt and colleagues presented the choices with level 1 evidence for efficacy. They include:
- Sumatriptan, 6 mg subcutaneous injection, or 20 mg nasal spray
- Zolmitriptan, 5 or 10 mg nasal spray
- Oxygen, 100%, 7 to 12 liters per minute via a mask over the nose and mouth
The authors recommend subcutaneous sumatriptan 6 mg and/or high-flow oxygen at 9- to 12- liters per minute for 15 minutes. Subcutaneous sumatriptan, they note, has been shown to achieve pain relief within 15 minutes in 75% of patients who receive it. Moreover, one-third report pain freedom. Oxygen’s efficacy has long been established, and relief comes with no adverse events. As for mask type, though no significant differences have been observed in studies, patients appear to express a preference for the demand valve oxygen type, which allows a high flow rate and is dependent on the user’s breathing rate.
Lidocaine intranasally has been found to be effective when triptans or oxygen do not work, according to a review in The Lancet Neurology by Hoffman and May. The medication is dripped or sprayed into the ipsilateral nostril at a concentration of between 4% and 10%. Pain relief is typically achieved within 10 minutes. This review also reports efficacy with percutaneous vagus nerve stimulation with the gammaCore device and neurostimulation of the sphenopalatine ganglion, though the mechanisms of these approaches are poorly understood.
Evolving therapies for acute cluster headache include the aforementioned CGRP receptor-antagonists. Additionally, intranasal ketamine hydrochloride is under investigation in an open-label, proof-of-concept study; and a zolmitriptan patch is being evaluated in a double-blind, placebo-controlled trial.
Attacks of migraine occur in 12% of the adult population, 3 times more in women than men and are painful and debilitating. Cluster attacks are even more painful and occur in about 0.1% of the population, somewhat more in men. Both types of headache have a variety of effective treatment as detailed above.
