Study Notes
Laxatives and Their Proper Use
- Bisacodyl (Dulcolax) should be administered with water only, as interactions with milk or juice can occur.
- All laxative tablets must be swallowed whole to avoid dependence, particularly with stimulant laxatives like bisacodyl.
- The standard for normal bowel movements is not strictly one per day; variability is normal.
Mineral Oil Laxatives
- Oral mineral oil can cause lipid pneumonia if aspirated into the respiratory tract, making aspiration a significant concern.
Bulk-Forming Laxatives
- Bulk-forming laxatives require intake of a full 8-ounce glass of water to prevent esophageal obstruction and fecal impaction.
- They increase water absorption, leading to bulkier intestinal contents and formed stools without significant systemic effects.
Bismuth Subsalicylate (Pepto-Bismol)
- Co-administration of oral hypoglycemic drugs with bismuth subsalicylate can decrease the absorption of the hypoglycemics.
Total Bowel Cleansing
- Polyethylene glycol (GoLYTELY) is the preferred drug for total bowel cleansing before diagnostic or surgical procedures.
Long-Term Laxative Use
- Long-term use of stimulant laxatives like senna (Senokot) can lead to reduced bowel tone and dependency; daily bowel movements are not essential for bowel health.
Antidiarrheal Medications
- Diphenoxylate with atropine (Lomotil) may lead to physical dependence, while loperamide (Imodium) has not been associated with physical dependence.
- Both Lomotil and Imodium are administered orally, and the differentiation in pharmacological action does not imply quicker action for Lomotil.
Constipation Prevention
- Patients seeking to prevent constipation should inquire about safe laxative options appropriate for their needs.
