Pantoprazole
One Protonix listing in Digestive Health sits on this shelf, in 20 mg and 40 mg gastro-resistant tablets of pantoprazole. This proton-pump inhibitor reduces stomach acid to treat Gastro-oesophageal Reflux Disease and Peptic Ulcer Disease.
Key points
- Listed for symptomatic reflux, long-term management of reflux oesophagitis, and prevention of NSAID-induced gastroduodenal ulcers in at-risk adults.
- Symptomatic improvement may mask the symptoms of gastric malignancy and delay diagnosis; alarm symptoms warrant exclusion of malignancy before treatment.
- Severe hypomagnesaemia has been reported after at least three months of use, and in most cases after a year, with symptoms including fatigue, tetany, and convulsions.
How does Pantoprazole work?
Pantoprazole is converted to its active form inside the acid-producing cells of the stomach lining, where it blocks the enzyme responsible for the final step of hydrochloric acid production. Because it acts at this late stage, it reduces acid output regardless of what triggered secretion, whether a meal, a hormonal signal, or a nerve impulse. The effect is dose-dependent and covers both baseline and stimulated acid levels.
