by1023 sodium

Pantoprazole sodium (Pantecta) is the sodium salt form of a substituted benzimidazole with proton pump inhibitor activity. Pantoprazole sodium is a lipophilic, weak base that crosses the parietal cell membrane and enters the acidic parietal cell canaliculus where it becomes protonated, producing the active metabolite sulfenamide, which forms an irreversible covalent bond with two sites of the H+ K+-ATPase enzyme located on the gastric parietal cell, thereby inhibiting both basal and stimulated gastric acid production.

Pantoprazole Sodium Hydrate (BY1023 (sodium hydrate)) is a proton pump inhibitor drug, used for short-term treatment of erosion and ulceration of the esophagus caused by gastroesophageal reflux disease.
