A 9 mg/ml sodium chloride (0.9%) infusion solution or a 50 mg/ml glucose (5%) infusion solution should be used.

1. Withdraw 5 ml of infusion solution from the 100 ml bottle or infusion bag using a syringe.
2. Add this volume to the vial containing the omeprazole lyophilizate and mix well until you are sure that all the omeprazole has dissolved.
3. Withdraw the omeprazole solution again using the syringe.
4. Transfer the solution to the infusion bag or bottle.
5. Repeat steps 1-4 until you are sure that all the omeprazole has been transferred from the vial to the infusion bag or bottle.

Alternative method of preparation of infusions in flexible containers

1. Use a double transfer needle and connect it to the injection membrane of the infusion bag. Connect the other end of the needle to the vial containing the omeprazole lyophilizate.
2. Dissolve the omeprazole by pumping infusion solution between the infusion bag and the vial and vice versa.
3. Check that all the omeprazole has dissolved.

Do not use if particles are observed in the reconstituted solution.

The infusion solution will be administered as an intravenous infusion over 20-30 minutes.
