New—and surprising—ways to approach migraine pain

Migraine headaches pose a challenge for many patients and their physicians, so new, effective approaches are always welcome. Sometimes new treatments come as total surprises. For example, who would have guessed that timolol eyedrops could be effective for acute migraine?1 Granted, the results (discussed in this issue's PURLs) are from a single randomized trial, but they look very promising.

This is not the only new and innovative treatment for migraine. Everyone knows about the heavily marketed calcium gene-related peptide antagonists, which include monoclonal antibodies and the so-called “gepants.” The monoclonal antibodies and atogepant are approved for migraine prevention, and they do a decent job (although at a high price). In randomized trials, these agents reduced migraine days per month by an average of about 1.5 to 2.5 days compared to placebo.2-5

Ubrogepant and rimegepant are approved for acute migraine treatment. In clinical trials, about 20% of patients taking ubrogepant or rimegepant were pain free at 2 hours post dose, compared to 12% to 14% taking placebo.6,7 Unfortunately, that means 80% of patients still have some pain at 2 hours. By comparison, zolmitriptan performs a bit better, with 34% of patients pain free at 2 hours.8 However, for those who can’t tolerate zolmitriptan, these newer options provide an alternative.

We also now have nonpharmacologic options. The caloric vestibular stimulation device is essentially a headset with ear probes that change temperature, alternating warm and cold. In a randomized controlled trial, it reduced monthly migraine days by 1.1 compared to placebo, from a baseline of 7.7 to 3.9 days.9 It can also be used to treat acute migraine. There is also a vagus nerve–stimulating device that reduced migraine headache severity by 20% on average in 32.2% of patients in 30 minutes. Sham treatment was as effective for 18.5% of patients, giving a number needed to treat of 6 compared to sham.10

And finally, there are complementary and alternative medicine options. Two recent randomized trials demonstrated that ≥ 2000 IU/d of vitamin D reduced monthly migraine days an average of 2 days, which is comparable to the effectiveness of the calcium gene-related peptide antagonists at a fraction of the cost.11,12 In another randomized trial, intranasal 1.5% peppermint oil was as effective as topical 4% lidocaine in providing substantial pain relief for acute migraine; about 42% of patients achieved significant relief with either treatment.13

While we may not have a perfect treatment for our patients with migraine headache, we certainly have many options to choose from.
