## **Core Concept**
The question tests the understanding of managing NSAID-induced peptic ulcers, focusing on the most specific treatment approach. NSAIDs can cause gastric mucosal damage leading to peptic ulcers by inhibiting cyclooxygenase (COX) enzymes, which are crucial for the production of protective prostaglandins in the stomach.

## **Why the Correct Answer is Right**
The correct answer, , is a proton pump inhibitor (PPI). PPIs are considered the most effective class of drugs for healing NSAID-induced peptic ulcers. They work by irreversibly inhibiting the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells, thereby reducing gastric acid secretion. This action helps in healing the ulcers by reducing acid production and thus minimizing further damage to the gastric mucosa.

## **Why Each Wrong Option is Incorrect**
- **Option A:** - This option is incorrect because, although is an H2 receptor antagonist that can reduce acid secretion, it is not as potent as PPIs in healing NSAID-induced ulcers.
- **Option B:** - This option is incorrect as is a mucosal protective agent but is not the first line or most specific treatment for NSAID-induced peptic ulcers.
- **Option D:** - This option is incorrect because, while could refer to various drugs, the context does not provide a clear alternative that is more specific or effective than PPIs for this condition.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that when using NSAIDs, concomitant use of PPIs (like ) can significantly reduce the risk of developing peptic ulcers, especially in high-risk patients. This approach is often recommended for patients on long-term NSAID therapy.

## **Correct Answer Line**
**Correct Answer: C. **
