Da. Marcus, Establishing a standard of speed for assessing the efficacy of the serotonin(1B/1D) agonists (triptans), ARCH NEUROL, 58(7), 2001, pp. 1056-1058
The current International Headache Society guidelines for migraine clinical
trials recommend assessment of pain relief at 2 hours as a primary end poi
nt. Patients, however, express a clear preference for more rapid pain relie
f, with most patients defining rapid relief as occurring within 30 minutes
after drug administration. Thus, consideration should be given to establish
ing clinical trial end points that more accurately reflect the preferences
of patients with migraine. In this case, assessment of pain relief at 1 hou
r would be an appropriate primary end point. Using speed of relief as a cri
terion for migraine drug selection also is appropriate. The migraine-specif
ic serotonin(1B/1D) agonists, or triptans, are able to meet this faster rel
ief end point and are preferred by patients.
