Structure of Rabeprazole
Rabeprazole is a benzimidazole derivative with a pyridine ring fused to a benzimidazole core, containing a sulfone group and an ethoxy methyl group.
Chemical Formula: C₁₈H₂₀N₄O₅S
Mode of Action
Rabeprazole functions as a proton pump inhibitor by irreversibly inhibiting the H⁺/K⁺-ATPase enzyme in gastric parietal cells.
It blocks the final step of acid production, resulting in prolonged acid suppression.
