Gamma Scintigraphy: a Useful Tool for Colon Targeted Drug Delivery: a Recent Non-invasive Approach of Determining Drug-transit Profile in Colon

Gamma Scintigraphy is a recent approach of determining transit profile and and target specificity of specific drug in colon and other body part. With this novel non-invasive approach,drug localization can be visualized in animal or human being under gamma camera after tagging with radio active substance. In this book a functional method of Gamma Scintigrapgy, process of tagging the radio active substance and a experimental study was discussed with a model drug. A detail process and method of preparing samples for this in-vivo study was demonstrated in details.
