Pharmacokinetics and Pharmacodynamics of the Proton Pump …
Cys813 is the primary site responsible for the inhibition of acid pump enzyme, where PPIs bind. Omeprazole was the first PPI introduced in market, followed by pantoprazole, lansoprazole and rabeprazole. Though these PPIs share the core structures benzimidazole and pyridine, their pharmacokinetics and pharmacodynamics are a little different.

Omeprazole: pharmacology, pharmacokinetics and interactions
Omeprazole is a prodrug which is converted to its active form only at the site of action, namely the parietal cell. There it binds irreversibly with H+-K+-ATPase (the gastric proton pump), which causes an effective and long-lasting inhibition of gastric …
