Brief summary:
This is an open label pilot study of 25 subjects with a diagnosis of episodic migraine with or without aura. STOPAIN is an over-the-counter product that is used for the temporary relief of minor aches and pains of muscles and joints associated with simple backache, arthritis, strains, bruises and sprains. We plan to have subjects apply the product during a single migraine attack to see if it will alleviate the headache pain and associated symptoms.

Detailed description:
This is an open label, 2 visit, pilot study of 25 subjects with a diagnosis of episodic migraine with or without aura according to the International Classification of Headache Disorders (2nd Edition-2004).

Subjects will be screened at Visit 1 after being properly consented for participation in the study. Screening procedures will include assessment of the medical history, headache history, current medications, vital signs, height and weight measurements and a urine pregnancy test for women of childbearing potential. Investigators will determine the eligibility of study subjects. Subjects will be instructed on how and when to apply the topical gel to treat a migraine attack. In addition, subjects will be instructed how to complete the take home diary. The study medication will be used at home to treat a single migraine attack.

At the time of at-home treatment the subject will apply the study medication. The gel will be applied to the area below and abutting the back base of the skull to base of neck and span from behind and between both ears. The quantity shall be two pumps from the metered dosing bottle. The best way to apply is to pump once onto the fingertips and apply the gel to one-half of the application area and pump again onto the fingertips and apply the gel to the other half of the application area. Massage in for 5 to 10 seconds to make sure there is reasonably uniform coverage. (Do not cover with cloth or bandage or lie down on a pillow until the gel has completely dried - about 10 minutes or so.) Do not get any of the gel into the eyes or onto mucus membranes. The gel is not toxic but will cause a burning sensation to eyes or mucus membranes. Wash hands with soap and warm water after application. The gel will give rise to a cooling sensation and to it may feel like a mild to moderate stinging or burning sensation. That is normal. Anything more than a mild to moderate stinging or burning sensation is not expected and should be noted in diary. If there has been no reduction in symptoms after 30 minutes repeat the application. If there is no relief after 2 hours the subject may use other rescue medication.

Completed subject diaries will provide data on headache severity and the presence or absence of nausea, vomiting, photophobia and phonophobia. Time of resolution of both the headache and accompanying symptoms will be collected. The subjects will record migraine pain severity and the presence or absence of associated symptoms at 30, 60, 90 minutes and 2, 4, and 24 hours after the administration of study drug.

Subjects will be asked to treat a single migraine attack within 8 weeks of Visit 1. After treating the attack and completing the diary, they will be asked to return to Jefferson Headache Center for a final visit (Visit 2) or to return the diary and other study supplies by mail. Shipping materials will be provided to each participant.
