Final answer:
Treatment for peptic ulcers caused by H. pylori typically includes a combination of antibiotics and acid reducers in a triple therapy regimen, which may consist of OAC, BMT, or LAC protocols depending on the specific case and resistance patterns.
Step-by-step explanation:
Treatment regimes for peptic ulcer caused by Helicobacter pylori (H. pylori) typically include a combination of antibiotics and acid-reducing medications. The triple therapy recommended by the US Food and Drug Administration involves a 10-day treatment with omeprazole, amoxicillin, and clarithromycin (OAC); or a 14-day treatment with bismuth subsalicylate, metronidazole, and tetracycline (BMT); or 10 or 14 days of treatment with lansoprazole, amoxicillin, and clarithromycin (LAC). The listed antibiotics are used to eradicate H. pylori, while omeprazole, bismuth subsalicylate, and lansoprazole serve to decrease the stomach acid levels, creating an unfavorable environment for H. pylori which thrives in acidic conditions. Due to H. pylori's resistance to certain antibiotics, these treatments are not always effective and may require different combinations or additional diagnostics like endoscopy.
