Minesapride is a partial agonist with a highly selective serotonin 4 (5-HT4) receptor. Minesapride enhances gastrointestinal peristalsis and colon transport by activating the 5-HT4 receptor. Minesapride increases bowel movements and suppresses visceral allergic reactions. Minesapride can be used in the study of constipation-type irritable bowel syndrome (IBS-C) [1].
