Large intestine motility and gut physiology

Large intestine motility and gut physiology refer to the coordinated muscular and secretory activities of the colon that facilitate the processing and elimination of waste. This system is governed by the enteric nervous system (ENS), which integrates signals from the central nervous system and local mechanical or chemical stimuli to regulate peristalsis and fluid transport, as described by StatPearls [1] and the NIH [5]. Disruptions in these physiological processes lead to common clinical conditions such as chronic idiopathic constipation (CIC), irritable bowel syndrome (IBS), and opioid-induced constipation (OIC), according to the Mayo Clinic [2]. While Large intestine motility and gut physiology is a broad physiological category rather than a single molecular target, it is the therapeutic focus for drugs like prucalopride (a 5-HT4 agonist) and linaclotide (a GC-C agonist), which aim to restore normal function by acting on specific receptors within the gut wall [3][4]. These interventions aim to normalize transit time and improve stool consistency by modulating muscle contraction and epithelial secretion.

Pharmacological agents modulate this system by targeting specific receptors and channels, such as 5-HT4 receptors to stimulate motility, guanylate cyclase-C (GC-C) to increase fluid secretion, or mu-opioid receptors to inhibit or restore transit [1][3][4].
