DA-9701 is a new prokinetic agent formulated with Pharbitis Seed and Corydalis Tuber. These plants have been used in oriental traditional medicine for the treatment of gastrointestinal maladies. In a stage 3 trial, its' efficacy has been compared to that of itopride in functional dyspepsia patients and proved to have comparable safety and efficacy. However, its' exact effect on the gastrointestinal motility has not been completely elucidated. This study will study the effects of DA-9701 on the healthy adult gastrointestinal tract.
