Definition and Purpose

• Acid suppression therapy aims to reduce stomach acid production to alleviate symptoms and prevent complications of gastroesophageal reflux disease (GERD) and other acid-related disorders.

Types of Acid Suppressants

• Histamine-2 (H2) blockers reduce acid production by blocking histamine receptors in the stomach.
• Examples of H2 blockers include ranitidine, famotidine, and nizatidine.
• Proton pump inhibitors (PPIs) inhibit the hydrogen/potassium ATPase enzyme to reduce acid production.
• Examples of PPIs include omeprazole, lansoprazole, and esomeprazole.
• Antacids neutralize stomach acid but do not reduce acid production.
• Examples of antacids include Tums, Rolaids, and Mylanta.

Indications

• Acid suppression therapy is used to treat gastroesophageal reflux disease (GERD).
• It is also used to treat peptic ulcer disease.
• Additionally, it is used to treat Zollinger-Ellison syndrome.
• Acid suppression therapy is used for stress ulcer prophylaxis in critically ill patients.

Adverse Effects

• Common adverse effects of H2 blockers include headache, diarrhea, and dizziness.
• Rare adverse effects of H2 blockers include thrombocytopenia and hepatotoxicity.
• Common adverse effects of PPIs include diarrhea, headache, and nausea.
• Rare adverse effects of PPIs include Clostridioides difficile infection, osteoporosis, and vitamin deficiencies.
• Common adverse effects of antacids include diarrhea, constipation, and flatulence.
• Rare adverse effects of antacids include milk-alkali syndrome and kidney stones.

Monitoring and Dosage

• Dosage varies depending on the specific medication and indication.
• Regular assessment of symptoms, endoscopy, and laboratory tests (e.g., complete blood count, liver function tests) are used to monitor acid suppression therapy.

Interactions and Contraindications

• Acid suppression therapy may interact with other medications, such as warfarin, phenytoin, and ketoconazole.
• Contraindications for acid suppression therapy include hypersensitivity to the medication, pregnancy, and breastfeeding (for some medications).

Acid Suppression Therapy

• Reduces stomach acid production to alleviate symptoms and prevent complications of acid-related disorders
• Works by inhibiting the proton pump in the stomach, reducing the release of hydrochloric acid and pepsin

Types of Acid Suppression Therapy

• Proton Pump Inhibitors (PPIs):
  • Most effective and widely used acid suppression therapy
  • Examples: omeprazole, lansoprazole, esomeprazole, pantoprazole, and rabeprazole
• Histamine-2 (H2) Receptor Antagonists:
  • Less effective than PPIs but still used for mild to moderate acid reflux
  • Examples: ranitidine, famotidine, nizatidine, and cimetidine
• Antacids:
  • Neutralize stomach acid but have short-term effects and may cause side effects
  • Examples: Tums, Rolaids, and Mylanta

Indications for Acid Suppression Therapy

• Gastroesophageal Reflux Disease (GERD):
  • Alleviate symptoms such as heartburn, regurgitation, and dyspepsia
• Peptic Ulcer Disease (PUD):

  • Reduce excessive gastric acid production
• Stress-Related Mucosal Damage:
  • Prevent bleeding and perforation in critically ill patients

Adverse Effects and Interactions of Acid Suppression Therapy
