    Abstract:
    Understanding factors influencing patients' preference will improve guidance to make rational choices in expanded symptomatic migraine treatment. The objective of this open-label, cross-over study was to explore patients' preferences for sumatriptan 50 mg vs. zolmitriptan 2.5 mg tablets, focusing on factors influencing this preference. One hundred consecutive migraine patients attending our clinics were asked to treat three attacks with each medication and then fill out a preference questionnaire. Ninety-four migraineurs completed the trial and 42 (44%, 95% CI 34-58%) reported that they preferred zolmitriptan 2.5 mg over sumatriptan 50 mg tablets and 27 (29%, 20-38%) preferred sumatriptan 50 mg. The remaining 25 (27%, 18-36%) did not show any preference. For the initial treatment of the attacks, there were more patients needing just one tablet of zolmitriptan 2.5 mg compared with sumatriptan 50 mg (67 vs. 39%). The reasons for preference among those 69 patients who had shown preference for either of the two triptans were: a faster onset of action (speed of onset) (73%), a longer duration of the effects (39%), fewer adverse events (35%) and lower price (13%). Only one-quarter of the studied migraine population thought that sumatriptan 50 mg and zolmitriptan 2.5 mg were equivalent, which suggests that most migraine patients differentiate between triptans. A faster onset of action (speed of onset) was the most important reason for preference.
