Cheap Migraine Drugs More Effective Than New Expensive Ones

By Pat Anson

Migraine treatment drugs known as triptans are more effective in relieving acute migraine pain than new expensive medications and should be used more widely, according to new study published in The BMJ.

A team of researchers at Oxford University analyzed the results from 137 clinical studies to see which migraine drugs were more effective in helping patients become pain-free after two hours and whether that relief was sustained 24 hours later. Nearly 90,000 people participated in the studies, over 85% of them women.

Four triptans - eletriptan, rizatriptan, sumatriptan, and zolmitriptan – were rated the best overall, ahead of rimegepant (Nurtec), ubrogepant (Ubrelvy) and lasmiditan (Reyvow) in efficacy and tolerability.

“Overall, the results of our network meta-analysis suggest that the best performing triptans should be considered the treatment of choice for migraine episodes owing to their capacity for inducing rapid and sustained pain freedom, which is of key importance for people with migraine,” wrote lead author Andrea Cipriani, MD, a professor of psychiatry and director of the Precision Psychiatry Lab at Oxford.

Triptans work by narrowing blood vessels in the brain and preventing the release of chemicals that cause migraine pain; while rimegepant and ubrogepant inhibit calcitonin gene-related peptides (CGRPs), a protein that triggers pain. Lasmiditan reduces pain by binding to serotonin receptors in the brain.

The drugs’ mechanisms of action are different and so is their cost. A packet of 6 tablets of eletriptan costs about $106, while a similar-sized packet of rimegepant (Nurtec) costs $1,061; ubrogepant (Ubrelvy) costs $1,097; and lasmiditan (Reyvow) is priced at $790. The cost of those three drugs is much higher because they are only available as brand name medications, while triptans are widely available in cheaper generic formulations.

Despite their cost and extensive marketing promoting their use, lasmiditan, rimegepant, and ubrogepant were rated no more effective in treating migraine pain than over-the-counter drugs such as acetaminophen (paracetamol) and non-steroidal anti-inflammatory drugs (NSAIDs). Researchers say those OTC pain relievers should be considered second line options, if triptans are ineffective.  

“While the recent introduction of lasmiditan, rimegepant, and ubrogepant has expanded options for the acute treatment of migraine, the high cost of these newer drugs, along with the substantial adverse effects of lasmiditan (dizziness), suggest their use as third line options, after the less expensive, similarly efficacious, second line options,” researchers said.

“Limited access to triptans and their substantial under-utilization represents missed opportunities to offer more effective treatments and deliver better quality of care to people who experience migraine.”

Some people can’t take triptans due to cardiovascular problems or unwanted side effects, but researchers say the best performing triptans should be included in the World Health Organization’s List of Essential Medicines to help expand their use.

Another recent study also rated triptans as superior to other migraine medications, although that research didn’t include the newer CGRP inhibitors.

Migraine affects about 39 million people in the United States and 1.1 billion worldwide. In addition to headache pain, migraine can cause nausea, blurriness, and sensitivity to light or sound. Women are three times more likely to suffer from migraines than men.  

Migraine Sufferers Rank Triptans as Most Helpful Medication

A large new study that compared the effectiveness of acute migraine medications found that triptans are two to five times more helpful than ibuprofen and acetaminophen in treating migraine attacks. Triptans were also found to be more effective than Excedrin migraine, opioids, and other non-steroidal anti-inflammatory drugs (NSAIDs).

The study used a unique methodology, gathering data on over 3 million migraine attacks reported by over 278,000 people in the US, UK and Canada who used a smartphone app during a six-year period. The Migraine Buddy app allows users to monitor the frequency of their migraine attacks, triggers and symptoms, and rate how “helpful” or “not helpful” their medications are.

“There are many treatment options available to those with migraine. However, there is a lack of head-to-head comparisons of the effectiveness of these treatment options,” said lead author Chia-Chun Chiang, MD, a neurologist who specializes in Headache Medicine and Vascular Neurology at the Mayo Clinic. “These results confirm that triptans should be considered earlier for treating migraine, rather than reserving their use for severe attacks.”

Chiang and his colleagues looked at a total of 25 medications among seven drug classes. Different dosages and medication combinations were combined in their analysis. Newer drugs that inhibit calcitonin gene-related peptides (CGRP) were excluded because they were not in wide enough use during the study period.

How Patients Rated Effectiveness of Acute Migraine Drugs

NEUROLOGY

The study findings, published in the journal Neurology, ranked several triptans (eletriptan, zolmitriptan, sumatriptan, rizatriptan, naratriptan, almotriptan and frovatriptan) as the most helpful medications, with about 75% effectiveness.

By comparison, acetaminophen (paracetamol) was helpful only 37% of the time.

“Our results strongly support the use of triptans, the first class of migraine-specific medication for the acute treatment of migraine,” researchers reported. “In practice, NSAIDs and acetaminophen are generally the first-line medications utilized for mild to moderate headache, and migraine-specific medications are often reserved for moderate to severe migraine attacks, which could potentially result in under-utilization of triptans or delayed treatment during migraine attacks.”

Participants found NSAID’s more effective than acetaminophen, with ketorolac helpful 62% of the time, indomethacin helpful 57% of the time, diclofenac helpful 56% of the time and ibuprofen helpful 42% of the time.

Excedrin migraine was effective only about half the time, about the same as tramadol and codeine. Opioids are usually not recommended for migraine because they’ve been associated with medication overuse headache.

“For people whose acute migraine medication is not working for them, our hope is that this study shows that there are many alternatives that work for migraine, and we encourage people to talk with their doctors about how to treat this painful and debilitating condition,” said Chiang.

Migraine affects about 39 million people in the United States and is the second leading cause of disability worldwide, according to the American Migraine Foundation.  

Another recent study that compared migraine prevention drugs found that two medications usually used to treat depression and high cholesterol are just as effective as the new CGRP inhibitors. Amitriptyline is a tricyclic antidepressant, while simvastatin is a statin. Both drugs are used off-label for migraine prevention and cost substantially less than CGRP drugs.
