A Novel Approach for the Administration of Medications and Fluids in Emergency Scenarios and Settings
Published on: November 9, 2016
Summary
Laxatives treat constipation and prepare bowels for procedures but can be dangerous if misused. Proper patient guidance is essential for safe and effective laxative use, especially with over-the-counter options.
Area of Science:
- Pharmacology
- Gastroenterology
Background:
- Laxatives are commonly used for constipation and bowel preparation.
- Many laxatives are available over-the-counter (OTC).
Purpose of the Study:
- To review available laxative types.
- To provide guidance on proper patient use of laxatives.
Main Methods:
- Literature review of laxative classifications.
- Discussion of safe prescribing and patient counseling.
Main Results:
- Overview of different laxative classes and their mechanisms.
- Identification of potential risks associated with laxative misuse.
Conclusions:
- Appropriate patient education is crucial for safe laxative therapy.
- Healthcare providers should ensure proper understanding of laxative use to prevent adverse events.

01:22Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives
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 makes...

01:20Drugs Affecting GI Tract Motility: Other Laxatives
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.

01:17Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents
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.

01:20Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents
Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.

01:17Drugs for Treatment of Diarrhea-Predominant IBS
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...

01:21Drugs 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...
