Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents01:17

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

367
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...

Inflammatory Bowel Disease V: Surgical Management

243
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Drugs for Treatment of Constipation-Predominant IBS

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 for Treatment of Diarrhea-Predominant IBS

348
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...

Inflammatory Bowel Disease IV: Pharmacological Management

224
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

207
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...

Area of Science:

  • Gastroenterology
  • Surgical Complications
  • Pharmacology

Background:

  • Postoperative ileus (POI) frequently complicates abdominal surgery, with potentially severe outcomes like renal failure.
  • While peri-operative management, including early rehabilitation, has reduced POI incidence, prolonged POI remains a significant issue, affecting up to 25% of colorectal surgery patients.

Purpose of the Study:

  • To elucidate the pathophysiological phases of postoperative ileus.
  • To analyze current pharmacological treatments for POI based on clinical trials.
  • To explore potential future pharmacological targets for managing POI.

Main Methods:

  • Literature review of published clinical trials.
  • Analysis of pathophysiological mechanisms of POI.
  • Discussion of pharmacological interventions and research avenues.

Main Results:

  • Postoperative ileus involves distinct neurological, inflammatory, and pharmacological phases.
  • Opiate analgesics significantly contribute to the 'pharmacological' phase of POI.
  • Current management strategies have limitations in addressing prolonged POI.

Conclusions:

  • Understanding the multi-phase pathophysiology of POI is crucial for effective management.
  • Further research into novel pharmacological targets is needed to improve patient outcomes and reduce the incidence of prolonged POI.
