Final answer:
Anti-ulcer drugs typically have the suffixes -tidine and -prazole, which identify H2 blockers and proton pump inhibitors, respectively. These medications reduce stomach acid production but do not treat H. pylori infections.
Step-by-step explanation:
The two suffixes commonly used to identify anti-ulcer drugs are -tidine and -prazole. H2 blockers, such as ranitidine, famotidine, and cimetidine, use the -tidine suffix. These medications work by decreasing the amount of acid made in the stomach. Proton pump inhibitors (PPIs), like omeprazole, use the -prazole suffix and are another class of anti-ulcer drugs that also reduce stomach acid production.
While both classes treat conditions like GERD and Zollinger-Ellison syndrome, they operate through different mechanisms in the body. It's important to note that while these drugs are effective at reducing stomach acid, they do not directly treat an H. pylori infection associated with many ulcers. In such cases, antibiotics are used.
