    Study Notes

    Treatment of Gastroesophageal Reflux Disease (GERD)

    • GERD is defined by the reflux of gastric contents into the esophagus due to an incompetent lower esophageal sphincter (LES).
    • Symptoms include heartburn and potential misdiagnosis as angina pectoris.
    • Non-drug therapies focus on lifestyle modifications:
      • Elevate the head of the bed to reduce nocturnal esophageal damage.
      • Promote weight reduction and avoid stress, smoking, spicy foods, and alcohol.
      • Caution with ulcerogenic drugs such as NSAIDs.
    • Drug therapies include:
      • Increasing LES pressure with medications like metoclopramide, domperidone, bethanechol, and erythromycin.
      • Reducing HCl secretion using H2 blockers and proton pump inhibitors.
      • Prokinetic agents to enhance gastric motility.
      • Antacids and combinations, e.g., Gaviscon.
    • Surgical options are available if medical treatments do not provide relief.

    Prokinetic Drugs

    • Prokinetic drugs improve upper gastrointestinal tract motility and gastric emptying.
    • Classes include:
      • Dopamine antagonists (e.g., metoclopramide, domperidone).
      • Serotonin (5-HT4) agonists (e.g., mosapride).
      • Cholinomimetics (e.g., bethanechol).
      • Macrolide antibiotics (e.g., erythromycin).

    Metoclopramide

    • Mechanism: Increases LES tone and enhances gastric emptying.
      • Blocks dopamine receptors, reducing their inhibitory effect on GIT motility.
      • Enhances cholinergic transmission without affecting small intestine or colonic motility.
    • Antiemetic properties are derived from blocking D2 receptors in the chemoreceptor trigger zone of the medulla.
    • Therapeutic uses:
      • Treats gastroesophageal reflux and gastric emptying disorders (e.g., diabetic gastroparesis).
      • Prepares patients for endoscopy by enhancing gastric evacuation.
      • Utilized in emergency surgery to prevent aspiration of gastric contents and manage nausea.
    • Adverse effects:
      • Commonly causes sedation and extrapyramidal side effects.
      • Can counteract nausea related to Parkinson’s drugs by blocking D2 receptors without affecting basal ganglia.

    Domperidone

    • Functions as a dopamine receptor blocker, primarily acting peripherally.
    • Weaker antiemetic properties compared to metoclopramide.
    • Associated with minimal hyperprolactinemia but can have a longer QT interval risk.

    Bethanechol

    • A muscarinic agonist that stimulates gastric smooth muscle and myenteric plexus.
    • Historically used for GERD and gastroparesis, but less favored now due to side effects.

    Macrolide Antibiotics (Erythromycin)

    • Act by stimulating motilin receptors, promoting gastric motility and emptying.
    • Effective in acute upper GI hemorrhage cases for gastric evacuation before endoscopy.
    • Tolerance develops rapidly with prolonged use.

    Antacids and Antacid-Alginic Acid Products

    • Gaviscon contains alginic acid, magnesium trisilicate, aluminum hydroxide, and sodium bicarbonate.
    • Alginic acid forms a viscous foam that acts as a raft on gastric contents, preventing reflux.

    Metoclopramide

    • No effect on small intestine or colonic motility.

    • Antiemetic action via blockade of D2 receptors in the chemoreceptor trigger zone (CTZ) of the medulla.

    • Therapeutic uses include:

      • Gastroesophageal reflux to enhance gastric emptying and increase lower esophageal sphincter (LES) pressure.
      • Disorders of gastric emptying, such as diabetic gastroparesis and postoperative gastric retention.
      • Pre-endoscopy (20 mg IV) to enhance gastric evacuation and peristalsis, preventing vomiting.
      • During emergency surgery and labor to evacuate the stomach and prevent aspiration of gastric contents.
      • Treatment of nausea and vomiting from various causes.

    • Adverse effects include:

      • Most common is sedation.
      • Extrapyramidal effects like dystonia and dyskinesia, especially in elderly patients.
      • Hyperprolactinemia due to D2 receptor blockade in the pituitary gland.

    • Drug interactions:

      • Anticholinergic drugs may antagonize prokinetic action.
      • Other dopamine blockers (e.g., antipsychotics) can precipitate acute extrapyramidal effects.

    Domperidone

    • Blocks peripheral D2 receptors, enhancing gastrointestinal motility without central nervous system (CNS) side effects.

    • Antiemetic effect is less potent than metoclopramide.

    • Therapeutic uses mirror those of metoclopramide, including counteracting nausea and vomiting from levo-dopa and bromocriptine during Parkinson's treatment by blocking D2 receptors in the CTZ.

    • Adverse effects:

      • Growing evidence suggests increased QT interval, posing risks of serious arrhythmia and sudden death.

    Comparison: Metoclopramide vs. Domperidone

    • Metoclopramide: Strong dopamine receptor blockade with central and peripheral effects, notable prokinetic and antiemetic properties, significant extrapyramidal side effects, and hyperprolactinemia.
    • Domperidone: Peripheral-only blockade, weaker antiemetic effect, minimal extrapyramidal side effects, and less hyperprolactinemia.

    Bethanechol

    • Stimulates muscarinic M3 receptors in smooth muscle of the gastrointestinal tract and myenteric plexus.
    • Previously used for gastroesophageal reflux disease (GERD) and gastroparesis, now rarely prescribed due to cholinergic side effects.

    Macrolide Antibiotics (e.g., Erythromycin)

    • Directly stimulate motilin receptors on gastrointestinal smooth muscle, promoting migrating motor complex onset.
    • Intravenous erythromycin (33 mg/kg) may benefit patients with gastroparesis, though tolerance develops rapidly.
    • Can be useful in acute upper gastrointestinal hemorrhage to promote gastric emptying of blood prior to endoscopy.

    Antacids and Antacid-Alginic Acid Products

    • Combination products, such as Gaviscon (alginic acid, Mg-trisilicate, Al-hydroxide, NaHCO3), create a viscous foam in the presence of saliva that floats on gastric contents.
    • This foam acts as a raft, preventing gastric reflux.

    Gastroesophageal Reflux Disease (GERD)

    • Defined as the reflux of gastric contents into the esophagus due to an incompetent lower esophageal sphincter (LES).
    • Common symptoms include heartburn and chest pain, which may be mistaken for angina pectoris.

    Non-Drug Therapies

    • Lifestyle modifications recommended:
      • Elevation of the head of the bed to reduce nighttime acid exposure.
      • Weight loss to alleviate pressure on the LES.
      • Avoiding triggers such as stress, smoking, spicy foods, alcohol, and ulcerogenic medications (e.g., NSAIDs).
