Study Notes

Antiulcer Drugs

  • Antiulcer drugs are used to treat peptic ulcers, GERD, and stress ulcers.
  • Examples of antiulcer drugs include antacids, histamine 2 blockers, proton pump inhibitors, and pepsin inhibitors.

Antacids

  • Examples of antacids include aluminum and magnesium.
  • Side effects of antacids include constipation (aluminum), diarrhea (magnesium), and electrolyte imbalance.
  • Take antacids with a small amount of fluid to ensure the drug reaches the stomach.
  • Do not take antacids within 1 hour before or 2 hours after taking other medications.

Histamine 2 Blockers

  • Examples of histamine 2 blockers include famotidine.
  • Action: reduce gastric acid by blocking histamine at H2 receptors in parietal cells in the stomach.
  • Uses: prevent and treat peptic ulcers, GERD, and stress ulcers.
  • Side effects: confusion, headaches, dizziness, diarrhea, constipation, nausea, rash, blurred vision, malaise, and decreased libido.
  • Adverse reactions: hepatotoxicity, cardiac dysrhythmias, and blood dyscrasias.
  • Contraindications: pregnancy, breastfeeding, and severe renal or liver disease.

Proton Pump Inhibitors

  • Examples of proton pump inhibitors include pantoprazole.
  • Action: reduce gastric acid by inhibiting hydrogen/potassium ATPase enzyme in gastric parietal cells.
  • Uses: used in H. pylori treatment with antibiotics.
  • Side effects: headache, insomnia, dizziness, dry mouth, and GI distress.
  • Contraindications: allergic reactions, pregnancy, and breastfeeding.
  • Interactions: take on an empty stomach as food can decrease effectiveness; take 30 minutes before other medications.

Pepsin Inhibitors

  • Examples of pepsin inhibitors include sucralfate.
  • Action: combines with gastric acid to form a thick paste that covers the ulcer, protecting it from acid and pepsin.
  • Side effects: drowsiness, constipation, GI distress, and hyperglycemia.
  • Contraindications: renal failure.
  • Interactions: other drugs may not be absorbed, give 1-2 hours around other drugs.

Assessment and Interventions

  • Assess pain, GI status, and renal function.
  • Interventions: take medications as directed, avoid smoking, avoid driving until the effect is known, eat food rich in Vitamin B12, and avoid foods that cause irritation.
  • Increase fluids, bulk, and exercise to prevent constipation.
  • Stop smoking and encourage a healthy diet.
