Summary

Triptans effectively treat acute migraine by targeting serotonin receptors. However, overuse of triptans can lead to medication overuse headache (MOH) more quickly than other pain relievers.

Area of Science:

  • Neuroscience
  • Pharmacology

Background:

  • Migraine affects 8.4% of Japan's population, with many cases undiagnosed or undertreated.
  • Advances in neuroscience led to triptans, selective serotonin (5-HT) receptor agonists for acute migraine.
  • Triptans offer effective migraine relief through cranial vasoconstriction and trigeminal inhibition.

Purpose of the Study:

  • To evaluate the efficacy and safety of triptans in migraine treatment.
  • To compare the risk of medication overuse headache (MOH) associated with triptans versus other migraine medications.

Main Methods:

  • Review of recent advances in clinical neuroscience and pharmacology.
  • Analysis of a prospective study on medication overuse headache (MOH) in 98 patients.
  • Comparison of critical duration and monthly intake frequencies for triptans, ergots, and analgesics leading to MOH.

Main Results:

  • Triptans are effective for acute migraine and preferred over ergots despite higher cost.
  • The mean critical duration for MOH onset was shortest for triptans (1.7 years).
  • Triptans had the lowest mean critical monthly intake frequency (18 doses) for MOH onset.

Conclusions:

  • Triptans are valuable acute migraine treatments with a strong scientific basis.
  • Overuse of triptans can lead to medication overuse headache (MOH) faster and at lower dosages than ergots or analgesics.
  • Awareness of MOH risk with triptan overuse is crucial for patient management.
