Final answer:
The treatment for peptic ulcer disease includes proton pump inhibitors, H2 receptor antagonists, and antacids, with the addition of antibiotics if an H. pylori infection is present.
Step-by-step explanation:
The recommended therapy for peptic ulcer disease includes all of the following options: proton pump inhibitors (PPIs), H2 receptor antagonists, and antacids. Proton pump inhibitors, like omeprazole (Prilosec), work by decreasing the amount of acid made in the stomach. H2 receptor antagonists, such as ranitidine (Zantac), famotidine (Pepcid AC), and cimetidine (Tagamet), also reduce the production of stomach acid and are used to treat ulcers and conditions like GERD. Antacids can quickly relieve symptoms such as heartburn and indigestion by neutralizing excess stomach acid. In cases where the ulcer is caused by H. pylori infection, antibiotics are necessary for treatment.
