Final answer:
The typical treatment for ulcers caused by H. pylori is antibiotics (option C), often in combination with acid-reducing medications as part of a triple therapy regimen.
Step-by-step explanation:
The typical treatment for ulcers that develop in response to H. pylori infections is antibiotics. Antacids may help relieve the symptoms like burning pain and indigestion, but they do not kill the bacteria. For H. pylori-induced ulcers, a combination therapy often termed 'triple therapy' is recommended. This usually includes two antibiotics to ensure the eradication of H. pylori, alongside a medication to reduce stomach acid — such as a proton pump inhibitor or a bismuth compound — which aids the healing process. An example of this triple therapy is 10 days of treatment with omeprazole, amoxicillin, and clarithromycin (OAC). Ranitidine, famotidine, and cimetidine are examples of H₂-receptor antagonists that reduce stomach acid but they are not typically used alone for H. pylori treatment.
