Study Notes
Mineral Oil Enema and Laxatives
- Mineral oil enema is used to lubricate the pathway for stool passage.
- Magnesium may accumulate, leading to anal leakage as a side effect, especially in renal patients.
- Use caution when administering anything with excess sodium to heart failure patients.
Side Effects and Drug Interactions
- Expected gastrointestinal side effects include bloating, gas, nausea, and stomach cramping.
- A lack of bowel movement after 12 hours and increased abdominal pain may indicate an intestinal blockage, requiring immediate medical attention.
- Antacids, H2 blockers, and PPIs can interact with stimulant laxatives.
- Dairy and antacids can accelerate the dissolution of enteric coatings, so they should be taken separately.
- Dulcolax has an enteric coating to prevent gastric irritation.
Anti-diarrheal Medication
- Loperamide works by binding to mu-opioid receptors in the gut to slow peristalsis, allowing more time for water reabsorption, resulting in more formed stools.
- Side effects of loperamide include dizziness and dry mouth. Diarrhea can worsen dehydration.
- It can cause drowsiness; avoid combining with other CNS depressants like antihistamines.
- Loperamide can cross the blood-brain barrier at higher doses, potentially causing opioid-like responses.
Gastroesophageal Reflux Disease (GERD) Treatment
- Heartburn is a primary symptom; people often start with antacids like calcium carbonate (Tums).
- For persistent symptoms, they may progress to aluminum hydroxide/magnesium hydroxide (Mylanta), H2 blockers, and finally PPIs, minimizing long-term PPI use.
- H. pylori testing is not indicated for GERD treatment.
H2 Receptor Antagonists (H2RAs)
- Common H2RAs include famotidine (Pepcid), ranitidine (Zantac), and cimetidine (Tagamet).
- Famotidine is used OTC for heartburn; prescription doses treat ulcers.
- Ranitidine was removed from the U.S. market due to carcinogenic concerns but returned as generic famotidine.
- Cimetidine can also treat heartburn and should be used cautiously in the elderly due to confusing side effects.
- Potential side effects include liver and kidney monitoring, as drugs can cross the blood-brain barrier.
Proton Pump Inhibitors (PPIs)
- DPIs include omeprazole (Prilosec), esomeprazole (Nexium), pantoprazole (Protonix), and lansoprazole (Prevacid).
- Most preferably taken in delayed-release gel capsules, should not be crushed or split.
- PPIs are more effective than H2RAs in blocking stomach acid but have a higher toxicity potential.
Constipation and Antacid Medications
- Milk of magnesia (magnesium hydroxide) acts as both an antacid and laxative, effective against constipation but may also cause diarrhea.
- Combination of magnesium hydroxide with aluminum hydroxide stabilizes effects between constipation and diarrhea.
- Mylanta (aluminum hydroxide + magnesium hydroxide) needs monitoring for sodium levels, particularly in heart failure patients on sodium-restricted diets.
Other Information
- Sucralfate and bismuth subsalicylate (Pepto-Bismol) coat the stomach and should be taken on an empty stomach for optimal effectiveness in treating ulcers or diarrhea.
- Note the component in Pepto, a salicylate related to aspirin.
- Laxatives should begin with basic fiber or stool softeners for prevention versus treatment of existing constipation.
