Background: There is evidence that headache response rates may be higher if triptans are used early when a migraine attack is still mild, as compared to when it is treated after pain has reached moderate or severe intensity., Methods: In this randomized, double blind, placebo controlled, parallel group clinical trial, 361 patients took either placebo, sumatriptan 50 mg, or sumatriptan 100 mg in a single attack study. The primary outcome measure was pain-free status at two hours., Results: In the intention to treat group, two hour pain free rates were 16%, 40%, and 50% in the placebo group, sumatriptan 50 mg group, and the sumatriptan 100 mg group respectively (p < 0.001, active treatment groups vs. placebo)., Conclusions: Both sumatriptan 50 mg and 100 mg were significantly superior to placebo for the pain-free end point at two hours. The pain-free response rates in this trial where sumatriptan was taken while the headache was still mild were generally higher than in older clinical trials where headache was treated after reaching a moderate or severe intensity.

Objective: To compare sumatriptan responders and nonresponders in a migraine population with regard to a number of clinical, psychiatric and psychologic features., Methods: Patients were drawn from a referral headache clinic population, and classified as responders or nonresponders. Clinical features were assessed by a written questionnaire. The lifetime prevalence of several psychiatric disorders was determined by the National Institute of Mental Health diagnostic interview schedule and personality factors were measured by the 16 Personality Factors (16PF) Questionnaire., Results: Nonresponders indicated less influence on their migraine by menstrual factors, had a higher lifetime prevalence of generalized anxiety, and showed 16PF scores indicating greater shyness, self-sufficiency and perfectionism. Nonresponders were also more imaginative and less socially outgoing., Conclusion: Although they must be interpreted with caution due to small sample size and the multiple comparisons made, our results indicate that there may be differences between sumatriptan responders and nonresponders with regard to a number of clinical, psychiatric and psychologic factors. These results suggest that biological differences exist between the two patient groups which likely account for both the differences in their responses to sumatriptan and in the clinical features noted above.

The triptans represent a major advance in migraine therapy but their cost per dose greatly exceeds that of many older treatments. There is evidence that for a significant proportion of migraine patients these new drugs can show a positive cost benefit and also improve quality of life. Cost benefit would be expected to be greatest in patients with more severe migraine attacks.

This multicentre, randomized, double-blind, placebo-controlled, parallel group dose-ranging study compared the efficacy and tolerability of four doses of sumatriptan nasal spray (2.5, 5, 10 and 20 mg) with a placebo, in the acute treatment of a single migraine attack. In total, 544 patients received the study medication as a single spray in one nostril, to treat a single migraine attack in the clinic. Efficacy assessments included the measurement of headache severity, clinical disability, and the presence/absence of associated symptoms. The incidence of headache recurrence was also assessed. The three highest doses of sumatriptan (5 mg 49%, 10 mg 46%, 20 mg 64%) were significantly better than the placebo (25%) at providing headache relief (moderate or severe headache improving to mild or none) 120 min after treatment (P

Objective: To study the clinical features and treatment given to episodic cluster headache patients in the Calgary region., Patients: Fifty-one (51) patients who responded to a media campaign, had previously been diagnosed by their family physicians, and who met International Headache Society (IHS) criteria for episodic cluster headache, formed the population for this study., Methods: The media campaign consisted of newspaper advertisements and radio publicity including physician interviews and talk shows. Patients were required to complete by 200-item questionnaire detailing clinical features and treatment of their cluster headache syndrome. Each patient was also interviewed by our research nurse for clarification and proper completion of questionnaire., Results: Fifty-one percent (51%) of our patients had short headache attacks lasting one hour or less. Almost one-half (45%) had three or four attacks per 24 hour period. Eighty-six percent (86%) had been referred to a neurologist. Sixty-nine percent (69%) had never used oxygen, but of those who had, one-half were still using it. Sumatriptan by injection had been tried by 26% of patients and of these, 93% considered it effective. Subcutaneous dihydroergotamine had been tried by 8%. For prophylaxis, 41% had tried methysergide, 31% prednisone, and 4% verapamil. Many patients had been prescribed migraine prophylactic drugs which are ineffective for cluster headache, and some had also undergone dental procedures or nasal and sinus surgeries., Conclusions: Many cluster headache patients had not, to their knowledge, been prescribed or used the best symptomatic and prophylactic treatments for cluster headache. This should be addressed through educational programs and through making up-to-date information on the treatment of cluster headache readily available to physicians and patients.
