Pantoprazole (Pantonix) is chemically a novel substituted benzimidazole derivative, which suppresses the final step in gastric acid production by forming a covalent bond to two sites of the H+, K+ - ATPase enzyme system at the secretory surface of the gastric parietal cell. This leads to inhibition of both basal and stimulated gastric acid secretion irrespective of the stimulus. The binding to the H+, K+ - ATPase results in duration of antisecretory effect that persists longer than 24 hours. Pantoprazole (Pantonix) is quantitatively absorbed and bioavailability does not change upon multiple dosing. Pantoprazole (Pantonix) is extensively metabolized in the liver. Almost 80% of an oral dose is excreted as metabolites in urine; the remainder is found in feces and originates from biliary secretion.
Pantoprazole (Pantonix) is indicated where suppression of acid secretion is of therapeutic benefit. Pantoprazole (Pantonix) is registered for the following indications: -

1. Peptic ulcer diseases (PUD)

2. Gastro esophageal reflux diseases (GERD)

3. Treatment of ulcer resistant to H2 receptor antagonists (H2RAs)

4. Treatment of ulcers induced by non-steroidal anti-inflammatory drugs (NSAIDs)

5. Gastrointestinal (GI) bleeding from stress or acid peptic diseases

6. Eradication of Helicobacter pylori (in combination with antibiotics)

7. Zollinger-Ellison syndrome

8. Prophylaxis for acid aspiration syndrome during induction of anaesthesia
Dosage & Administration
Delayed release tablet
The usual recommended adult oral dose is 40 mg given once daily, before breakfast. The duration of therapy is ranging from 2-8 weeks. Duodenal Ulcers: Pantonix 40 mg tablet, once daily for 2 to 4 weeks. Duodenal ulcer generally heals within 2 weeks. Gastric ulcers: Pantonix 40 mg tablet, once daily for 4 to 8 weeks. Gastric ulcer generally heals within 4 weeks. Reflux esophagitis: Pantonix 40 mg tablet, once daily for 4 to 8 weeks. Reflux esophagitis generally heals within 4 weeks of treatment. In resistant ulcers: Pantonix 40 mg tablet, once daily for 8 weeks. Ulcers induced by NSAIDs: Pantonix 40 mg tablet once daily, in patients receiving continuous treatment with NSAIDs. GI bleeding from stress or acid peptic diseases: Usual adult oral dosage, if required the dosage may be increased. Eradication of Helicobacter pylori: Triple therapy of Pantonix 40 mg twice daily in combination with appropriate antibiotic for one week achieved eradication rates of 90 to100%. Zollinger-Ellison syndrome: 4 Pantonix 40 mg tablets per day. Once control of acid secretion has been achieved, the dose should be gradually reduced to the lowest effective dose that maintains acid control. Prophylaxis for acid aspiration syndrome during induction of anaesthesia: 1 or 2 Pantonix 40 mg tablet should be given the evening before surgery and repeated again the morning of surgery.


Intravenous Pantoprazole should be replaced with oral therapy as soon as possible.
