Study Notes
Gastric Acid Reducers
- Block basal and nocturnal gastric acid secretion, reducing the production of gastric acid and alleviating symptoms of duodenal ulcers.
- Contraindications and precautions:
- Misoprostol: contraindicated in pregnancy and lactation
- Omeprazole: use with caution in pregnancy and lactation
- Pantoprazole: contraindicated in pregnancy and lactation
- Interactions:
- Digoxin and phenytoin levels may increase when used concurrently with omeprazole
- Ketoconazole, itraconazole, and atazanavir absorption decreased when taken concurrently with proton pump inhibitors
- Clopidogrel effects decreased when used concurrently with proton pump inhibitors
- Nursing actions:
- Monitor digoxin and phenytoin levels carefully
- Avoid concurrent use of ketoconazole, itraconazole, and atazanavir with proton pump inhibitors
- Monitor for thrombotic events with concurrent use of clopidogrel
- Administration:
- Do not crush, chew, or break sustained-release capsules
- Do not open capsule and sprinkle contents over food to facilitate swallowing
Mucosal Protectant
- Sucralfate:
- Forms a protective barrier on the ulcer, protecting it from acid and pepsin
- Minimal systemic absorption, mostly eliminated in feces
- Complications: constipation
- Contraindications and precautions:
- Hypersensitivity to the medication
- Client education:
- Increase dietary fiber and fluid intake to prevent constipation
Antacids
- Neutralize or reduce gastric acid, can reduce pepsin activity
- Therapeutic uses:
- Treatment of peptic ulcer disease
- Prevention of stress-induced ulcers
- Relief of GERD symptoms
- Complications:
- Constipation (aluminum compounds)
- Diarrhea (magnesium compounds)
- Fluid retention (sodium-containing antacids)
- Electrolyte imbalances (aluminum and calcium compounds)
- Client education:
- Alternate use of antacids to offset intestinal effects
- Avoid antacids containing sodium if hypertensive or heart failure
- Report manifestations of hypercalcemia
- Contraindications and precautions:
- Use with caution in clients with abdominal pain, GI perforation, or obstruction
- Interactions:
- Antacids decrease absorption of several medications, including famotidine and cimetidine
- Aluminum compounds bind to warfarin, digoxin, and tetracycline, reducing their effects
- Nursing administration:
- Administer frequently (up to 7 times a day)
- Encourage compliance by reinforcing the intended effect of the antacid
Eradication of H. pylori
- Purpose: eradication of H. pylori bacteria
- Therapeutic uses:
- Combination therapy with antibiotics for 14 days
- Nursing administration:
- Administer metronidazole with food to decrease gastric disturbances
- Client education:
- Take the full course of prescribed medications
- Adverse effects reverse when dosing stops
- Contraindications and precautions:
- Use with caution in pregnancy and lactation
- Older adults may experience adverse CNS effects and may require decreased dosage
