Answer to Question 1

ANS: A
Misoprostol, a GI prostaglandin, is used to prevent and treat gastric ulcers caused by NSAIDs. Prostaglandin inhibition is effective in reducing pain and inflammation, especially in arthritis, but makes the patient more predisposed to peptic ulcers. Prostaglandins are normally present in the GI tract to inhibit gastric acid and pepsin secretion to protect the stomach and duodenal lining against ulceration. NSAIDs inhibit prostaglandin production. Bismuth subsalicylate, metronidazole, and tetracycline combination (Helidac), as well as lansoprazole, clarithromycin, and amoxicillin combination (Prevpac), are used to treat infections caused by Helicobacter pylori. Drug interactions are not prevented by the presence of antiulcer medications.

Answer to Question 2

ANS: C
All H2 receptor antagonists end in dine. Examples in this category include cimetidine, ranitidine, famotidine, and nizatidine. An example of a protokinetic agent is metoclopramide. An example of a proton pump inhibitor is omeprazole.
An example of a coating agent is sucralfate.
