Objective:   To substantiate the long-term safety and tolerability of sumatriptan nasal spray (SNS) in an adolescent population of migraineurs aged 12 -17 years.


  • In this open-label, multicenter, observational study, adolescent migraineurs 12-17 years treated an unlimited number of migraine attacks meeting IHS criteria for up to 12 months with SNS.
  • Eligible subjects must have had an average of at least 2 migraine attacks per month in each of the 2 months prior to study entry and a typical attack duration of approximately 4 hours or more.
  • All subjects started treatment with the 20 mg. dose of SNS; a dosage decrease to 5 mg. may have been made at the investigator’s discretion in order to optimize a subject’s tolerability and efficacy needs.
  • A second dose of study drug was permitted for subjects who attained complete or partial relief 2 hours after initial dosing and then experienced a recurrent or worsening of pain.
  • Adverse events were assessed during monthly phone calls and during study visits, which occurred at 3-month intervals.
  • An ECG, laboratory evaluations, and physical examination were performed at study entry and at the final study visit; an intranasal exam was performed mid-treatment and at the final study visit.
  • Efficacy data, including migraine severity and recurrence, were collected from subjects approximately 24 hours after theintial treatment of every migraine attack.
  • Subjects had not participated in previous long-term safety and/or efficacy studies of SNS.
Conclusions:  Sumatriptan nasal spray 20 mg. was shown to be well-tolerated and efficacious during long-term use by adolescent migraineurs aged 12 to 17 years.
