Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

989
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...

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 for Treatment of Diarrhea-Predominant IBS

954
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 for Treatment of Ulcerative Colitis in IBD

675
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs Affecting GI Tract Motility: Other Laxatives

1.5K
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...

Inflammatory Bowel Disease V: Surgical Management

905
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:

Summary

Ischaemic colitis, a serious condition, can be induced by loperamide, an anti-diarrheal medication. This case report suggests a link between loperamide use and the development of bowel necrosis.

Area of Science:

  • Gastroenterology
  • Clinical Medicine
  • Pharmacology

Background:

  • Ischaemic colitis is a severe condition often caused by reduced blood flow to the intestines.
  • Loperamide is a common medication for managing diarrhea.
  • The etiology of ischaemic colitis can be multifactorial, including vascular and non-vascular causes.

Observation:

  • A 62-year-old male with no prior abdominal issues presented with severe abdominal pain and distension.
  • The patient had recently been treated with loperamide for diarrhea.
  • Emergency surgery revealed necrotic segments of the colon and terminal ileum.

Findings:

  • Surgical findings indicated extensive bowel necrosis.
  • No evidence of thromboembolic events was identified as the cause.

  • Loperamide was identified as a potential causative agent for the ischaemic colitis.

    • Implications:

    • This case highlights a potential adverse effect of loperamide, suggesting it as an iatrogenic cause of ischaemic colitis.
    • Clinicians should consider loperamide's role in patients presenting with symptoms suggestive of ischaemic colitis, especially after recent use.
    • Further investigation into the mechanism by which loperamide may induce ischaemic colitis is warranted.
