Use of Rectal Dialysis Technique to Measure Rectal 5-ASA Levels in Healthy Volunteers Receiving Asacol

Summary

The investigators plan to develop a novel method of estimating 5-ASA levels in the rectum at a mucosal level using in vivo rectal dialysis technique towards the eventual goal of determining the optimal dosing of Asacol® that would provide therapeutic levels of 5-ASA in the left colon.
