Drugs used for peptic ulcer

Introduction to Peptic Ulcer

A peptic ulcer, a common ailment that affects millions worldwide, is a sore that forms on the lining of the stomach, the upper part of the small intestine, or the lower oesophagus. It’s a result of the stomach’s protective lining being worn away, exposing it to digestive acids. This article aims to provide an in-depth understanding of peptic ulcer, its pathogenesis, pathophysiology, and treatment, complete with examples and flowcharts for a comprehensive understanding.

Peptic ulcers include:

  1. Gastric ulcers occur on the inside of the stomach.
  2. Duodenal ulcers occur inside the upper portion of your small intestine (duodenum).
  3. Esophageal ulcers occur inside the oesophagus. 

Pathogenesis of Peptic Ulcer

The pathogenesis of peptic ulcer disease involves an imbalance between aggressive factors, such as gastric acid and pepsin, and defensive factors, like mucus and bicarbonate secretion, prostaglandins, and blood flow to the gastric mucosa. Let’s delve deeper into the role of two major culprits: Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs). 

Role of Helicobacter pylori in Peptic Ulcer

Helicobacter pylori, a spiral-shaped bacterium, colonizes the stomach lining, causing inflammation and ulcers. It disrupts the stomach’s protective mucus layer, making it more susceptible to the harmful effects of acid and pepsin. The bacterium also produces toxins that contribute to the ulcer formation.

Role of NSAIDs in Peptic Ulcer

Non-steroidal anti-inflammatory drugs (NSAIDs) are another leading cause of peptic ulcers. They inhibit the production of prostaglandins, substances that protect the stomach lining and regulate gastric acid secretion. Long-term or high-dose use of NSAIDs can result in peptic ulcer disease.

Pathophysiology of Peptic Ulcer

The pathophysiology of peptic ulcer disease involves several steps, starting with the disruption of the gastric or duodenal lining. This disruption leads to exposure of the underlying cells to gastric acid and pepsin, resulting in ulceration. If not properly managed, these ulcers can penetrate deeper layers, leading to complications like bleeding or perforation.

Clinical Manifestations of Peptic Ulcer

Peptic ulcers can present with various symptoms, the most common being a burning or gnawing pain in the upper abdomen. Other symptoms include bloating, heartburn, nausea, and vomiting. However, some people may have a “silent” ulcer with no apparent symptoms.

Diagnostic Procedures for Peptic Ulcer

Diagnosis of peptic ulcer disease involves a combination of clinical history, physical examination, and specific tests such as endoscopy and tests for Helicobacter pylori. An endoscopy allows direct visualization of the ulcer, while H. pylori tests detect the presence of the bacterium.

Treatment Strategies for Peptic Ulcer

The treatment of peptic ulcer disease aims to relieve symptoms, heal the ulcer, and prevent complications. It involves a combination of medications, lifestyle modifications, and in some cases, surgery.

Pharmacological Treatment of Peptic Ulcer

Treatment for peptic ulcers depends on the cause. It usually involves killing the H. pylori bacterium (if present), eliminating or reducing NSAIDs, and helping your ulcer heal with medication. Pharmacological treatment includes proton pump inhibitors (PPIs), H2-receptor blockers, antacids, and antibiotics for H. pylori eradication. These medications reduce gastric acid production or neutralize it, promoting ulcer healing. 

Classification of Drugs Used in Peptic Ulcers

Surgical Treatment of Peptic Ulcer

Surgery for peptic ulcer disease is reserved for cases where complications occur, such as perforation, bleeding, or when the ulcers do not respond to medical treatment. Surgical procedures include vagotomy, antrectomy, and pyloroplasty.

Lifestyle Modifications for Peptic Ulcer Management

Lifestyle modifications can aid in managing peptic ulcer disease. These include avoiding NSAIDs, limiting alcohol, quitting smoking, and stress management. A balanced diet rich in fruits, vegetables, and whole grains also promotes gut health.

Complications of Peptic Ulcer

If left untreated, peptic ulcers can lead to serious complications, including bleeding, perforation, and gastric outlet obstruction. These complications can be life-threatening and require immediate medical attention.

Peptic Ulcer in Special Populations

Certain populations, such as the elderly and those with comorbid conditions, may experience different symptoms and complications from peptic ulcer disease. Management strategies may also differ in these groups.

Peptic Ulcer and Mental Health

The link between peptic ulcer disease and mental health is a growing area of research. Stress and anxiety can exacerbate ulcer symptoms, and living with a chronic condition like peptic ulcer disease can also contribute to mental health issues.

Prevention of Peptic Ulcer

Prevention strategies for peptic ulcer disease include avoiding risk factors like NSAIDs and H. pylori infection, maintaining a healthy lifestyle, and regular medical check-ups, especially for high-risk patients.


Peptic ulcer disease is a complex condition with a multifactorial etiology. Understanding its pathogenesis, pathophysiology, and treatment strategies can help in its effective management and prevention. With the right knowledge and tools, we can make strides in reducing the burden of this prevalent disease.

What causes a peptic ulcer?

The most common causes of peptic ulcers are infection with the bacterium Helicobacter pylori and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs).

What are the symptoms of a peptic ulcer?

Symptoms of a peptic ulcer include burning stomach pain, feeling of fullness, bloating, intolerance to fatty foods, heartburn, and nausea.

How is a peptic ulcer diagnosed?

Peptic ulcers are usually diagnosed based on the patient’s symptoms and medical history. An upper gastrointestinal endoscopy is the most accurate method to diagnose peptic ulcers.

How are peptic ulcers treated?

Treatment for peptic ulcers depends on the cause. It usually involves killing the H. pylori bacterium (if present), eliminating or reducing use of NSAIDs, and medications to decrease stomach acid.

Can peptic ulcers be prevented?

Yes, by limiting the use of NSAIDs, eliminating H. pylori with antibiotics if present, and making lifestyle changes like quitting smoking and reducing alcohol consumption.

Can peptic ulcers lead to cancer?

In rare cases, long-standing peptic ulcers can lead to stomach or duodenal cancer.
