Abstract
Migraineurs (94F, 24M) with previous experience of subcutaneous sumatriptan and/or sumatriptan tablets were asked their opinion on sumatriptan nasal spray treatment particularly with respect to onset of action, total efficacy, tolerability, and user friendliness. The information was obtained by means of a self-administered questionnaire handed out at the time of prescription of the nasal spray. The results are based on the patients' cumulative experience of having treated at least two migraine attacks with the spray (20 mg). Sumatriptan nasal spray (20 mg) was perceived to have a faster onset of action and, with the exception of a bad taste, to have a better tolerability than the tablets. Compared with subcutaneous sumatriptan, the nasal spray was claimed to be less effective in reducing symptoms of migraine attacks but to cause fewer adverse events. A bitter taste was the most commonly reported side effect of sumatriptan nasal spray--reported by 68% (80 out of 118) of the migraineurs. The user friendliness of sumatriptan nasal spray was rated better than that of subcutaneous sumatriptan and/or sumatriptan tablets. The overall impression of sumatriptan nasal spray was reported to be better or equal to that of the tablet and the injection by 57% and 46%, respectively. It is concluded that the results obtained in clinical practice are very much in line with those obtained in controlled clinical trials. The overall impression of sumatriptan nasal spray is that it is user friendly and useful in the acute treatment of migraine attacks of moderate intensity.
