Time to 10%, 50%, 90% and Complete Gastric Empting of the Radioactive Markers Representing Sumatriptan, Naproxen and Eletriptan
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).
