Recommended Dosage for Pathological Hypersecretion Including Zollinger-Ellison Syndrome

•
The recommended adult dosage of PROTONIX I.V. is 80 mg every 12 hours by intravenous injection (over at least 2 minutes) or intravenous infusion (for 15 minutes).
•
Adjust the frequency of dosing to individual patient needs based on acid output measurements. In those patients who need a higher dosage, 80 mg intravenously every 8 hours is expected to maintain acid output below 10 mEq/h.
•
When switching between intravenous to oral formulations of gastric acid inhibitors, consider the pharmacodynamic action of the drugs to ensure continuity of acid suppression.

Preparation and Administration Instructions for GERD Associated with a History of EE

​15-Minute Intravenous Infusion for Pediatric or Adult Patients

​1. Reconstitute each vial of PROTONIX I.V. with 10 mL of 0.9% Sodium Chloride Injection.

​2. Dilute the resulting solution to a final concentration as described below:

•
​Pediatric patients 3 months to less than 1 year of age: Dilute with 21 mL 0.9% Sodium Chloride Injection to a final concentration of approximately 1.3 mg/mL.
•
​Pediatric patients 1 year to 17 years old and adult patients: Further dilute with 100 mL 5% Dextrose Injection or 0.9% Sodium Chloride Injection to a final concentration of approximately 0.4 mg/mL.

3. Inspect the diluted PROTONIX I.V. solution visually for particulate matter and discoloration prior to and during administration.

4. Withdraw the desired dose of the diluted PROTONIX I.V. solution for a pediatric or adult dose.

5. Discard any unused portion of the remaining PROTONIX I.V. solution.

6. Infuse intravenously over a period of approximately 15 minutes through a dedicated line or through a Y-site.

7. Flush the intravenous line before and after administration of PROTONIX I.V. with either 5% Dextrose Injection or 0.9% Sodium Chloride Injection.

2-Minute Intravenous Injection for Adult Patients

1. Reconstitute each vial of PROTONIX I.V. with 10 mL of 0.9% Sodium Chloride Injection, to a final concentration of approximately 4 mg/mL.

2. Withdraw the dose of 40 mg of reconstituted PROTONIX I.V. solution.

3. Inspect the diluted PROTONIX I.V. solution visually for particulate matter and discoloration prior to and during administration.

4. Administer intravenously over a period of at least 2 minutes.

5. Flush the intravenous line before and after administration of PROTONIX I.V. with either 5% Dextrose Injection or 0.9% Sodium Chloride Injection.
