New Migraine Treatments: Triptans Outperform Latest Options

In recent developments in migraine treatment, the spotlight has turned to the efficacy of newer migraine medications compared to well-established treatments. A comprehensive meta-analysis featured in the BMJ has captured the attention of healthcare professionals and migraine sufferers alike, as it sheds light on the comparative effectiveness of various oral medications used for acute migraine relief.

The analysis evaluated data from 137 clinical trials encompassing approximately 90,000 adults. The aim was to assess the efficacy of all licensed oral medications available for the acute treatment of migraines in adults. Among the medications reviewed, older-generation oral drugs known as triptans—specifically eletriptan, rizatriptan, sumatriptan, and zolmitriptan—emerged as the frontrunners in terms of efficacy. These triptans demonstrated superior outcomes compared to the newest classes of migraine medications, namely gepants and ditans, represented by drugs like lasmiditan, rimegepant, and ubrogepant.

Karlsson WK, Ostinelli EG, Zhuang ZA, and colleagues, researchers from the UK and Denmark, spearheaded the study published in the BMJ. They highlighted that the newer classes, despite being recent entries into the market, did not markedly outperform commonplace analgesics like acetaminophen, ibuprofen, and aspirin in terms of migraine pain relief. This finding is significant given that the newer drugs command a higher cost and present notable side effects—factors that may lead healthcare providers to consider them as secondary or tertiary options in treatment plans.

The meta-analysis employed widely accepted outcome measures recommended by the International Headache Society. These included the number of participants who were pain-free at two hours post-medication and those who maintained pain freedom for 24 hours. Among their conclusions, researchers found that eletriptan consistently outperformed most others with odds ratios (ORs) for two-hour pain freedom ranging between 1.46 and 3.01. In contrast, ibuprofen showed strong results for sustaining pain freedom over 24 hours with ORs between 3.16 and 4.82.

The researchers called attention to the affordability and comparable efficacy of generic triptans, despite their usage ranging only from 16.8% to 22.7% in the United States. This discrepancy in use is partly attributed to existing contraindications, particularly for patients with vascular diseases. However, the study authors argued for a re-evaluation of these limitations, suggesting that triptans should be viewed as a primary treatment option, potentially to be included in the WHO List of Essential Medicines for their global accessibility and established efficacy.

While the introduction of gepants and ditans expands the therapeutic landscape for individuals with contraindications to triptans, the study authors, including Grace Halsey, emphasized the need for further research into the cost-effectiveness and long-term utility of these new classes of migraine medications. The affordability barrier, alongside the potential for severe side effects such as those noted with lasmiditan, positions these newer drugs as third-line options in the hierarchy of migraine treatment.

In conclusion, the meta-analysis as presented by Karlsson WK and colleagues insists on a strategic deployment of existing and new migraine medications. Both triptans and NSAIDs prove effective; however, selective application based on individual patient profiles and the economic context remains imperative. These findings provide clinicians with a robust evidence base for guiding treatment choices, ultimately aiming for optimized patient outcomes in migraine management.
