Long-term tolerability of sumatriptan nasal spray in adolescent patients with migraine
Abstract
OBJECTIVE: This 1-year, open-label, multicenter study was designed to assess the long-term tolerability and efficacy of sumatriptan nasal spray 20 mg in adolescent patients with migraine.
METHODS: A prospective, multicenter, open-label study was conducted in patients aged 12 to 17 years who were allowed to treat an unlimited number of migraines at severe, moderate, or mild pain intensity with sumatriptan nasal spray for up to 1 year. All patients started the study at the 20-mg dose of sumatriptan nasal spray. Dose could be adjusted downward to 5 mg at the discretion of the investigator to optimize therapy.
RESULTS: A total of 484 adolescent migraineurs treated 4676 migraines with sumatriptan nasal spray 20 mg (3593 during the first 6 months and 1083 during the second 6 months). A total of 3940 migraines and 699 migraines were treated with one and two 20-mg doses of sumatriptan nasal spray, respectively. Only 10 patients (treating 42 migraines) took the 5-mg dose of sumatriptan nasal spray. The overall percentage of migraines treated with either one 20-mg dose or one, two, or three 20-mg doses with at least 1 drug-related adverse event was 19%. The most common specific drug-related adverse event was unpleasant taste, reported in 17% of migraines. No other single drug-related adverse event was reported in more than 1% of migraines over the 1-year treatment period. When unpleasant taste was excluded from the adverse-event tabulations, the percentages of migraines with at least…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 4,334 participants or records.
