Drugs for Treatment of Constipation-Predominant IBS01:21

Drugs for Treatment of Constipation-Predominant IBS

160
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: Bulk-Forming and Stimulant Laxatives

204
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...

Drugs Affecting GI Tract Motility: Other Laxatives

200
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...

Drugs for Treatment of Diarrhea-Predominant IBS

161
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

77
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

255
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Area of Science:

  • Pediatric Gastroenterology
  • Pharmacology
  • Clinical Trial Methodology

Background:

  • Functional constipation is common in children, often requiring long-term laxative therapy.
  • The potential for weaning laxatives after achieving improved bowel function remains largely unexplored.
  • This study introduces a protocol for stimulant laxative weaning in pediatric patients.

Purpose of the Study:

  • To describe a standardized protocol for stimulant laxative weaning in children with functional constipation.
  • To evaluate the early outcomes of this weaning protocol.

Main Methods:

  • Patients on stable laxative doses for six months were eligible.
  • Laxative doses were reduced by 10-25% every two weeks, with adjustments based on symptom recurrence.
  • Success was defined by sustained daily bowel movements without constipation symptoms.

Main Results:

  • Sixteen children were evaluated, with a median age of 12.7 years and a history of laxative use for 8 years.
  • 56.3% of patients successfully weaned off laxatives within a median of 3.7 months.
  • Patients on higher initial doses showed a higher success rate in weaning.

Conclusions:

  • A structured approach to weaning stimulant laxatives is effective in pediatric functional constipation.
  • The protocol demonstrated success, particularly in children requiring higher laxative doses.
  • Further research is needed to validate these findings in prospective studies.
