Randomized, placebo-controlled comparison of early use of frovatriptan in a migraine attack versus dosing after the headache has become moderate or severe.
OBJECTIVE
To evaluate whether frovatriptan would provide greater relief if given early during a migraine attack.


METHODS
Adults with a history of migraine of at least 1 year, and who had 2-8 headaches in the previous month were recruited from 19 US centres for a prospective, placebo-controlled crossover study over 2 migraine attacks. Dose 1 was taken at the onset of mild migraine headache, Dose 2 was taken at least 2 h later if the headache progressed to moderate/severe. Patients were randomized to receive Dose 1 frovatriptan then Dose 2 placebo or Dose 1 placebo followed by Dose 2 frovatriptan. Treatment order was reversed for the second attack. This schedule enabled a comparison of frovatriptan with placebo and a comparison of early and later treatment with frovatriptan.


METHODS
Freedom from pain at 2 h for frovatriptan versus placebo as Dose 1; use of Dose 2 and/or rescue medication, pain severity, functional impairment and headache recurrence.


RESULTS
In 241 patients who each treated 2 migraine attacks, Dose 1 frovatriptan was more effective than placebo in terms of the proportion of patients who were pain free at 2 h (28% vs 20%, p = 0.04). This benefit was sustained up to 4 h post-dose (p = 0.003). Early use of frovatriptan significantly reduced re-medication (p < 0.001). Twenty-four-hour headache recurrence was low in both early (4%) and later use (6%) groups. Sustained pain-free response occurred in 40% of frovatriptan early use patients compared with 31% of later use patients (p < 0.05). Early use prevented headache progression: 69%-78% had mild/no headache 2-4 h after Dose 1 frovatriptan compared with 54%-63% taking Dose 1 placebo (p < 0.001). Early use reduced pain burden and functional disability (p < or = 0.001). More patients rated early use of frovatriptan as excellent or good (57% vs 46%).


CONCLUSIONS
Early use of frovatriptan resulted in a higher, earlier and sustained pain-free response, prevented progression to moderate/severe headache and reduced pain burden and functional disability.
