This question requires identifying the correct statement regarding the prevention (prophylaxis) of peptic ulcers, particularly in a clinical context.
Based on clinical evidence, Proton-pump inhibitors (PPIs) play a significant role in the prophylaxis of peptic ulcers by reducing gastric acid production, thereby protecting the gastric mucosa from damage.
With regard to Helicobacter pylori eradication in peptic ulcer disease, consider the following statements:
1. Proton-pump inhibitor is taken with two antibiotics.
2. Treatment is prescribed for at least 7 days.
3. Treatment of Helicobacter pylori infection leads to vitamin B12 deficiency.
4. Patients requiring long-term NSAIDS should undergo Helicobacter pylori eradication therapy to reduce ulcer risk.
Which of the statements given above are correct?
