Why should PPI tablets not be chewed or crushed?

Enteric coatings protect medication from the acidic environment of the stomach, ensuring it breaks down and releases its active ingredients in the small intestine where it is needed.

What are H2RAs and how do they work?

H2RAs (Histamine type 2 receptor antagonists) like cimetidine, ranitidine, famotidine, and nizatidine work by blocking histamine receptors in the stomach, reducing acid production, and alleviating heartburn symptoms.

What is the difference between Antacids and H2RAs regarding their action on heartburn?

While both can effectively address heartburn, antacids work faster by directly neutralizing stomach acid, while H2RAs offer longer-lasting relief by reducing acid production in the stomach.

What are the recommended doses of OTC H2RAs for different severity of heartburn?

Individuals with mild and infrequent heartburn may find lower-dose OTC H2RA products like famotidine 10 mg sufficient, while higher-dose options like famotidine 20 mg are recommended for moderate symptoms.

What dosage adjustment is needed for H2RAs in patients with impaired renal function?

In individuals with impaired renal function (creatinine clearance < 50 mL/minutes), a reduced daily dose of H2RAs is recommended to avoid potential complications.

What are the general recommendations for OTC heartburn medications?

Antacids and H2RAs are recommended for mild to moderate heartburn and dyspepsia, and should not be taken at the same time as other medications as interaction could affect medication absorption or damage enteric coatings.

What is a potentially serious side effect associated with H2RAs?

Thrombocytopenia - a rare adverse effect related to H2RAs - involves a decrease in platelets leading to potential bleeding risks. This effect, however, is reversible upon stopping the medication.

Study Notes

Heartburn, Dyspepsia & Intestinal Gas

  • Heartburn is a form of indigestion (dyspepsia), often called gastro-esophageal reflux disease (GERD).
  • GERD occurs when stomach acid flows back into the esophagus, irritating the lining.
  • Symptoms often include a burning sensation behind the breastbone (retrosternal).
  • Heartburn is more common in older adults but can affect younger adults and pregnant women.
  • Similar symptoms can be caused by other conditions like peptic ulcers, delayed gastric emptying, gallbladder disease, or other GI disorders.

Signs and Symptoms of Heartburn

  • Typical symptoms include heartburn (burning chest pain), regurgitation (acid or food coming back up), and trouble swallowing.
  • Burning discomfort often starts in the upper stomach area and moves upward towards the breastbone.
  • Pain may be localized to the lower retrosternal area or extend to the throat, sometimes with an acidic taste in the mouth.
  • Heartburn frequently occurs within one hour of eating, especially after large meals or consuming trigger foods.
  • Atypical (extraesophageal) symptoms include stomach upset, flatulence, chest pain, unexplained cough/wheezing, hoarseness/sore throat, nausea, and vomiting.

Signs and Symptoms Severity

  • Mild symptoms bother the patient slightly without interfering with daily activities.
  • Moderate symptoms are more bothersome and interfere with normal activities.
  • Heartburn occurring two or more times a week suggests GERD.
  • "Alarm features" (severe pain, sudden onset, radiating pain, difficulty swallowing, regurgitation, worsening over time, persistent symptoms, or response to antacids failing) indicate a need for medical evaluation.

Precipitating Factors for Heartburn

  • Lifestyle factors: Obesity, pregnancy, large or late meals before bed, certain trigger foods (coffee, chocolate, peppermint, tomatoes, garlic, onion, citrus fruits, fried, fatty, spicy foods), smoking, alcohol consumption, stress, and anxiety.
  • Medications: Calcium channel blockers, antidepressants with antimuscarinic effects, theophylline, nitrates, iron supplements, phosphodiesterase inhibitors, NSAIDs, aspirin, oral corticosteroids, and bisphosphonates.

Exclusions for Self-Management

  • Children and individuals aged 55+ with alarm features. Severe pain, sudden onset, radiating pain, difficulty swallowing, or severe or worsening symptoms require a doctor's evaluation.
  • Regurgitation or difficulty swallowing (dysphagia) that is severe, persistent, or worsening. This could suggest obstruction or a more serious condition.
  • Symptoms persisting despite treatment or worsening over time. This warrants a doctor's consult.
  • Other concerns: Unexplained weight loss, difficulty swallowing (dysphagia), blood in vomit or stool, unexplained abdominal pain for more than 5 days, symptoms related to medications, or a lump/mass in the stomach.

Questions for Self-Management

  • Patient's age and previous history
  • Duration of symptoms and specifics, like location and character
  • Associated factors: pregnancy, diet, medications, stress, etc
  • Relieving or aggravating factors
  • Symptoms related to medications

Dyspepsia (Indigestion)

  • Indigestion is upper abdominal discomfort or pain, often self-diagnosed.
  • Many patients use indigestion and heartburn interchangeably though symptoms can overlap.
  • Indigestion is often mild and infrequent and rarely requires medical advice.

Signs and Symptoms of Dyspepsia

  • Poorly localized upper abdominal pain between the navel (umbilicus) and ribs.
  • Burning sensation (heartburn), heaviness, or aching in the upper abdomen related to eating, excess food, alcohol, or medications (e.g., NSAIDs or aspirin).
  • Symptoms like nausea, fullness in the upper abdomen, or belching can accompany indigestion.

Precipitating Factors for Dyspepsia

  • Diet: fatty foods, excessive consumption of spicy or acidic foods, or large meals
  • Smoking and alcohol consumption (especially in large amounts)
  • Medications: NSAIDs, aspirin, clopidogrel
  • Underlying conditions: gall bladder abnormalities if excessive consumption of oily or fatty food

Management of Heartburn & Dyspepsia

  • The treatment aims for complete symptom relief, reduction in recurrence, and medication side effect management.

Non-pharmacological Management

  • Weight loss for overweight/obese individuals
  • Avoid trigger foods
  • Smaller meals, especially the evening meal, 3-4 hours before bed
  • Stop smoking and reduce alcohol consumption
  • Elevate the head of the bed
  • Sleep on the left side
  • Avoid tight clothing around the abdomen
  • Stress and anxiety management (relaxation techniques)

Pharmacological Management

  • Antacids: Rapidly alleviate symptoms for short-term use. Sodium bicarbonate, aluminum and magnesium salts, Calcium carbonate.
  • Alginates: Form a protective barrier that helps prevent stomach acid from refluxing. Available as suspensions, chewable tablets, and other forms; often taken after meals or at bedtime
  • H2 receptor antagonists (H2RAs): Longer lasting relief for more frequent, intermittent heartburn.
  • Proton pump inhibitors (PPIs): Most effective for frequent or severe heartburn.

Additional Points

  • Antacids and H2RAs can be taken at different times to minimize interactions.
  • High sodium antacids are contraindicated for pregnant women or those on low-sodium diets.
  • Important to note that some medications may interfere with other types of medications so consult with a pharmacist or physician first.
  • Discuss the potential risks and benefits of medication usage with appropriate medical professionals

Special Populations

  • Geriatric patients: A short course of a PPI may be acceptable for heartburn but should aim to avoid drugs that can worsen existing delirium.
  • Renal Impairment: Use lower doses of antacids or H2RAs. Avoid drugs with high risks of adverse effects and consult healthcare providers.
  • Pregnancy and Breastfeeding: Alginates are safe, H2RAs can be used, but omeprazole, esomeprazole, and lansoprazole may be present in breast milk.
