Subtype classification of functional constipation in children: polyethylene glycol versus lactulose
1Department of Pediatrics, Konkuk University Medical Center, Konkuk University School of Medicine, Seoul, Korea.
Summary
Classifying childhood constipation subtypes using a colon transit time (CTT) test guides initial drug selection. This approach improves therapeutic outcomes for pediatric functional constipation.
Area of Science:
- Pediatric Gastroenterology
- Clinical Therapeutics
- Diagnostic Imaging
Background:
- Functional constipation is a common pediatric issue.
- Accurate classification of constipation subtypes is crucial for effective treatment.
- Colon transit time (CTT) testing offers a method to subtype functional constipation.
Purpose of the Study:
- To assess the therapeutic value of classifying functional childhood constipation subtypes.
- To determine if CTT test-based classification aids in initial drug selection for pediatric constipation.
Main Methods:
- Study involved 190 children with functional constipation.
- Data collected via defecation diaries, CTT tests, and medical records.
- Analysis focused on prescription patterns of polyethylene glycol (PEG) 4000 based on CTT subtypes.
Main Results:
- PEG 4000 was more frequently prescribed for abnormal transit constipation (91.8%) than normal transit (51.1%).
- Prescription rates for PEG 4000 varied significantly across CTT subtypes (NT, OT, ST) and fecal incontinence status.
- Higher PEG 4000 use was observed in outlet obstruction and slow transit subtypes, and in children with fecal incontinence.
Conclusions:
- CTT test-based classification of functional constipation provides valuable therapeutic insights.
- This classification aids in the initial selection of pharmacologic agents for pediatric constipation.
- Tailoring treatment based on CTT subtypes can optimize management strategies.

01:21Drugs for Treatment of Constipation-Predominant IBS
608
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...

01:22Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives
471
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...

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 for Treatment of Diarrhea-Predominant IBS
534
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...

01:17Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents
551
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.

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.
