Question 1 of 5
Which class of drugs is successful in treating an ulcer caused by H. pylori?
Correct Answer: Antacids relieve symptoms. H2 blockers and PPIs reduce acid but don't kill H. pylori. Antibiotics eradicate the bacteria, treating the ulcer's cause.
Rationale: The correct answer is C: Antibiotics. Antacids (choice
A) only provide symptomatic relief by neutralizing stomach acid. H2-receptor blockers (choice
B) and proton-pump inhibitors (choice
D) are used to reduce stomach acid secretion but do not directly target H. pylori bacteria.
Choice C, antibiotics, are successful in treating ulcers caused by H. pylori because they specifically target and eradicate the bacteria, addressing the root cause of the ulcer.
Therefore, antibiotics are the most effective class of drugs for treating H. pylori-induced ulcers.
