H2 Antagonists are a class of drugs that work to reduce the production of acid in the stomach. Zantac and Prevacid (A) are both proton pump inhibitors, not H2 Antagonists. Privinil and Tagamet (B) are ACE inhibitors, used to lower blood pressure, and NSAIDs, used to reduce pain and inflammation, respectively, not H2 Antagonists. Vasotec and Motrin (D) are also an ACE inhibitor and NSAID, respectively. Therefore, the only correct pair of drugs that are H2 Antagonists is Pepcid and Zantac (C).
