Pantoprazole is which type of gastric acid suppression agent?

Pantoprazole is a proton pump inhibitor. It irreversibly inhibits the H+/K+-ATPase pump in gastric parietal cells, blocking the final step of acid secretion and producing potent, long-lasting suppression of gastric acid. This distinguishes it from H2 receptor antagonists such as cimetidine and ranitidine, which reduce acid by blocking histamine receptors and are generally less potent. It also differs from sucralfate, which protects the mucosa by forming a barrier rather than reducing acid production. PPIs are typically given before meals because pumps are more active then, and pantoprazole acts as a prodrug activated in the acidic environment to achieve acid suppression.
