Inclusion Criteria
  • Consented males and nonpregnant females using adequate contraception, between 18 and 55 years of age, with at least 1-6 migraines per month for past 6 months. Subjects will be excluded for confirmed or suspected ischemic heart disease, uncontrolled hypertension at screening; a history of epilepsy or structural brain lesions which lowered the convulsive threshold; confirmed or suspected cardiovascular, cerebrovascular, peripheral vascular, congenital heart disease, or ischemic bowel disease; impaired hepatic or renal function; basilar or hemiplegic migraine. Other exclusion criteria included use of a monoamine oxidase inhibitor within 2 weeks before screening; ergot prophylactics in past 3 months; anticoagulants; smoking more than 10 cigarettes/day, evidence of alcohol or substance abuse; GI bleeding disorders, inflammatory bowel disease; or any concurrent medical or psychiatric condition that in the investigator's opinion could affect interpretation of efficacy or safety information or which otherwise contraindicated participation in the study.

Time to 10%, 50%, 90% and Complete Gastric Empting of the Radioactive Markers Representing Sumatriptan, Naproxen and EletriptanDay 1 of each treatment administration (For 30 days)

Scintigraphic images were analyzed in a time-lapse format and regions of interest were drawn to include the stomach and small intestine. Images were recorded in a supine position and a series of 3 to 60 consecutive anterior scintigraphic images, each 1 minute in duration, were recorded using a clinical grade gamma camera. After this initial continuous imaging sequence, additional images were recorded to coincide with pharmacokinetic (PK) blood sampling times as necessary to monitor the tablet disintegration and transit time through the intestines. Prior to ingesting the radiolabeled dosage forms, two external markers (2-3 microcuries of indium-111 or technetium-99m) were placed on each participant to facilitate consistent positioning underneath the gamma camera. The first marker was placed on the right side of the participant's chest (approximately at the fifth intercostal rib) and a second marker was placed on the hip bone (approximately the left anterior superior ileac spine).
