Which medication class is contraindicated in patients with a history of peptic ulcer disease?

• A. Antibiotics
• B. Nonsteroidal anti-inflammatory drugs (NSAIDs)
• C. Proton pump inhibitors
• D. Antispasmodics

Answer: (B)

Nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated in patients with a history of peptic ulcer disease due to their mechanism of action and potential to exacerbate existing gastrointestinal issues. NSAIDs work by inhibiting cyclooxygenase (COX) enzymes, which play a crucial role in the production of protective gastric mucosa. As a result, the use of NSAIDs can lead to a decrease in prostaglandins that help maintain the integrity of the stomach lining. This can increase the risk of gastric mucosal damage, which in turn may lead to the formation or worsening of ulcers.

In contrast, antibiotics are generally not contraindicated and are often used to treat infections, including those contributing to peptic ulcer disease. Proton pump inhibitors are actively used to reduce stomach acid and promote healing of ulcers and antispasmodics primarily help alleviate gastrointestinal cramping and do not pose the same risk as NSAIDs. Therefore, NSAIDs represent the significant risk for those with a history of peptic ulcer disease.
