    Study Notes

    Gastroesophageal Reflux Disease (GERD)

    • Pathophysiology: Retrograde flow of gastrointestinal (GI) contents into the esophagus, causing inflammation.
    • Results: Hyperemia (increased blood flow), erosion (damage to the tissue), and minor bleeding.
    • Common Cause: Relaxation of the lower esophageal sphincter.
    • Pharmacology: Drugs used to treat GERD include histamine receptor antagonists, proton pump inhibitors, prokinetic medications, antacids, and mucosal protectants.

    Peptic Ulcer Disease

    • Pathophysiology: Corrosive action of gastric acid on vulnerable esophageal lining caused by an imbalance between mucosal defenses and acid/peptic injury.
    • Causes: Acid erosion, H. Pylori bacterial infection, and NSAID use.
    • Pharmacology: Treatments include proton pump inhibitors (e.g., omeprazole), antacids, and antibiotics.

    Histamine Receptor Antagonists

    • Mechanism of Action (MOA): Block H2 receptors, suppressing gastric acid secretion.
    • Therapeutic Effects: Reduced gastric acid production and lower hydrogen ion concentration.
    • Use: Treating and preventing gastric and duodenal ulcers, GERD, and heartburn.
    • Complications/Side Effects: CNS effects (lethargy, hallucinations, restlessness); constipation, diarrhea, nausea, and GI bleeding.
    • Interactions: Antacids, warfarin, smoking, potentially affecting absorption with some medications.

    Proton Pump Inhibitors

    • MOA/Purpose: Inhibit the enzyme that produces gastric acid to reduce acid secretion.
    • Therapeutic Affect and Use: Short-term treatment for ulcers and GERD, prevention of stress ulcers.
    • Side Effects: Reduced acid production, reduction in gastric acid secretion.

    Antacids

    • MOA/Purpose: Neutralize or reduce the acidity, protect the mucosa.
    • Use: Alleviating symptoms of heartburn and peptic ulcers.
    • Side Effects: Constipation, diarrhea, hypercalcemia.
    • Interactions: Can decrease the absorption of other medications, requiring a time gap between taking antacids and other drugs.

    Prokinetics

    • MOA/Purpose: Enhance acetylcholine action, blocking dopamine and serotonin in the CNS to increase gastric emptying and control nausea/vomiting.
    • Therapeutic Effects: Increased gastric emptying; treatment of postoperative nausea, vomiting, and GERD.
    • Side Effects: Tardive dyskinesia, extrapyramidal symptoms (involuntary muscle movements), sedation, and diarrhea.

    Mucosal Protectants (Sucralfate)

    • MOA/Purpose: Acidic environment of the stomach changes medication into a protective barrier on the ulcer walls, acting as a shield to prevent further acid and pepsin breakdown.
    • Use: Acute duodenal ulcers, maintenance therapy.
    • Side Effects: Constipation, digoxin, warfarin, ciprofloxacin interactions (timing).

    Prostaglandin E Analog (Misoprostol)

    • MOA/Purpose: Decreases acid secretion, increases bicarbonate and protective mucus secretion, promoting vasodilation to damaged areas and decreasing acidity.
    • Use: Long-term NSAID use, to prevent ulcers and to induce labor

    Gastroenteritis

    • Pathophysiology: Inflammation of the stomach and small intestine lining, causing increased luminal fluid leading to depletion of intravascular fluid, malabsorption of nutrients, and symptoms like pain, vomiting, and diarrhea.
    • Treatment: Antidiarrheals, antibiotics, and antiemetics.

    Hernia

    • Pathophysiology: Protrusion of intestines through an abnormal opening due to straining, lifting heavy objects, or sudden twists or pulls.

    Hemorrhoids

    • Pathophysiology: Swollen or dilated veins in the anorectal area (internal or external).
    • Treatment: Topical anesthetics (benzocaine, lidocaine), protectants/emollients (mineral oil), astringents (witch hazel), and corticosteroids.

    Muscle Strain

    • Cause: Injury to muscle tissue due to overuse, trauma, or other factors.

    Antidiarrheals

    • MOA/Purpose: Activate opioid receptors in the GI tract to decrease intestinal motility increasing fluid absorption.

    Antiemetics

    • MOA/Purpose: Blocking specific receptors, like serotonin or dopamine, preventing nausea and vomiting, including nausea associated with pregnancy/post-operative cases/and chemotherapy.
