Drugs for Treatment of Constipation-Predominant IBS

1.4K
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs Affecting GI Tract Motility: Other Laxatives

1.6K
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Irritable Bowel Syndrome

DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility...

Drugs for Treatment of Diarrhea-Predominant IBS

970
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives

877
Laxatives enhance bowel movements and alleviate constipation. They augment the stool's bulk, stimulate intestinal muscle contractions, draw water into the intestines, or soften the stool. There are five key types of laxatives: bulk laxatives, stimulant laxatives, osmotic laxatives, stool softeners, and lubricant laxatives.
Bulk-forming laxatives, such as psyllium, methylcellulose, and polycarbophil, absorb water in the intestine, increasing stool bulk and promoting bowel movement. This...

Area of Science:

  • Gastroenterology
  • Pharmacology

Background:

  • Chronic constipation is a prevalent disorder with evolving treatment landscapes.
  • Poorly responsive constipation may stem from medication side effects (e.g., opioids), defecation disorders, or colonic dysmotility.

Purpose of the Study:

  • To review advancements in characterizing pancolonic motility.
  • To summarize evidence on established and novel drug efficacy for idiopathic and opioid-induced constipation.
  • To present a new algorithm for evaluating chronic idiopathic constipation refractory to laxatives.

Main Methods:

  • Literature review focusing on recent developments in chronic constipation evaluation and treatment.
  • Analysis of studies on pancolonic motility assessment.
  • Synthesis of clinical trial data for pharmacological interventions.

Main Results:

  • Enhanced characterization of pancolonic motility provides deeper pathophysiological insights.
  • Established and novel drugs demonstrate efficacy in treating both idiopathic and opioid-induced constipation.
  • A novel algorithm is proposed for managing patients with chronic idiopathic constipation inadequately responding to laxatives.

Conclusions:

  • Recent developments offer improved methods for evaluating and treating chronic constipation.
  • Understanding pancolonic motility is key to advancing therapeutic strategies.
  • New treatment algorithms and pharmacological options enhance patient care for refractory constipation.
