Comparative pharmacokinetics of (S)-MP3950, a novel 5-HT4 receptor agonist, in normal and atropine-induced gastrointestinal motility disorders rats

1. (S)-MP3950 is the (S)-enantiomer of active metabolite of mosapride, which exhibits higher 5-HT4 receptor agonistic effect than mosapride. It shows promise to become a novel drug candidate for the treatment of gastrointestinal motility disorders (GMDs). However, the pharmacokinetic behavior of (S)-MP3950 in the pathological state of GMDs remains unclear. Herein, we investigated the comparative pharmacokinetics of (S)-MP3950 in normal and GMDs...
