Once Daily Versus Conventional Dosing of Asacol in the Maintenance of Quiescent Ulcerative Colitis

The purpose of this study is to determine if taking Asacol once a day is as effective as taking Asacol twice or three times a day in keeping ulcerative colitis inactive, and to determine which dosing regimen is easiest to follow. Once daily dosing of Asacol is experimental, and has not been approved by the FDA. Dosing as three times daily is FDA approved. This research is being done because the researchers want to learn what the best methods are for keeping ulcerative colitis inactive, and which way of taking Asacol is most helpful to subjects in continuing to take a medication to control their ulcerative colitis.
