Final Answer:
The indicated medication groups for peptic ulcer disease would be B. Proton pump inhibitors and D. Antibiotics.
Step-by-step explanation:
Peptic ulcer disease often involves the presence of Helicobacter pylori bacteria, necessitating the use of antibiotics (D) to eradicate the infection. Additionally, proton pump inhibitors (B) are recommended to reduce stomach acid production, aiding in the healing of ulcers. These medications work synergistically to alleviate symptoms and promote ulcer healing.
Proton pump inhibitors, such as omeprazole and lansoprazole, hinder the action of proton pumps in the stomach's parietal cells, substantially decreasing acid secretion. This reduction in acid levels assists in ulcer healing by providing a less acidic environment. Antibiotics targeting H. pylori, like clarithromycin or amoxicillin combined with metronidazole, are typically prescribed in a multi-drug regimen for about two weeks to eradicate the bacterial infection, hence aiding in ulcer resolution.
Although histamine2-receptor antagonists (A) and antacids (C) can alleviate symptoms associated with peptic ulcers by temporarily reducing stomach acid, they are not sufficient for treating the root cause, particularly the H. pylori infection. Thus, while they might provide short-term relief, they are not the primary medications for addressing peptic ulcer disease. Hence, the optimal combination for treating peptic ulcers involves proton pump inhibitors to suppress acid production and antibiotics to eradicate the underlying bacterial infection.
