Evaluation of Brain Activation in Complete Responders and Partial Responders Following Acute Administration of Treximet (Sumatriptan and Naproxen)
We are looking for volunteers who suffer from acute migraine (<14 episodes per month) to
participate in a 2-visit brain imaging research study. The goal of the study is to observe
the effect of acute administration of Treximet during a migraine episode on the pain
pathways of the migraine brain. Visit 1 will consist of 1 hour, where participants will be
signing the informed consent form, completing questionnaires, meeting with the study
physician, and having QST (sensory testing to determine individual pain thresholds to a heat
stimulus) performed. Visit 2 will occur during a migraine episode. Volunteers will be
asked to contact the study team at the first onset of a migraine. Upon arrival at Visit 2,
individuals will be given an IV for blood draws. Once these the IV is in place, subjects
will enter the MRI and be asked to stay very still. Scanning will occur for about 20
minutes, and then subjects will be given a Treximet tablet to combat their migraine. More
scanning will follow Treximet administration. Some scans will have no stimulation, and
others will apply a heat stimulus that subjects will rate using a pain scale. Seven 5-mL
blood samples will be drawn throughout the duration of the MRI session. Both Visit 1 and
Visit 2 will be compensated.
