24.Patients considering undergoing elective gastric bypass surgery, or any other bariatric surgical procedures at any time after Study Visit 1.
25.Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of study drugs including, but not limited to, any of the following:
•History of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection.
•Currently active or previously active inflammatory bowel disease during the 12 months prior to Study Visit 1.
