μμ© κΈ°μ : Pantoprazole is a substituted benzimidazole weak base. It accumulates in the highly acidic environment of the gastric parietal cell secretory canaliculi, where it is protonated and converted into its active sulfenamide form. * **Mechanism:** The active form binds **irreversibly via covalent disulfide bonds** to the **H+/K+ ATPase enzyme system** (the "proton pump") at the secretory surface of gastric parietal cells. * **Pathway:** Systemic circulation β Parietal cell β Acidic canaliculi β Active sulfenamide β **Irreversible inhibition of H+/K+ ATPase** β Profound suppression of both basal and stimulated gastric acid secretion. Because the binding is irreversible, acid secretion only resumes when new proton pump enzymes are synthesized by the parietal cell, explaining the prolonged duration of action despite rapid systemic clearance.

Limited information available in veterinary species. A single oral dose of 887 mg/kg was lethal in dogs, causing acute toxic signs including ataxia, hypo-activity, and tremor. In humans, single oral overdoses up to 600 mg have been reported without adversity. In the event of a large overdose, contact an animal poison control center for guidance.
