Which suffix indicates a proton pump inhibitor?

Which suffix indicates a proton pump inhibitor?

• A. H2 receptor antagonists
• B. Prokinetics
• C. Proton pump inhibitors
• D. Antacids

Answer: (C)

The key idea is recognizing drug-name suffixes that point to a class. Proton pump inhibitors are identified by the -prazole suffix in their names (for example, omeprazole, pantoprazole). These drugs block the proton pump in gastric parietal cells, reducing acid production. Other GI meds use different suffixes or no universal suffix at all: H2 receptor antagonists typically end with -tidine, while antacids and prokinetics don’t share a single identifying suffix. So the option that names the proton pump inhibitors as a class best fits the suffix clue, making it the correct choice.
