Method of administration:
Injection:
Omeprazole IV injection is obtained by adding 10 ml Sodium Chloride 0.9% to the vial containing powder. After reconstitution the injection should be given slowly over a period of at least 2.5 minutes as a maximum rate of 4 ml per minute. The reconstituted IV injection should be used within 4 hours if stored at room temperature.
Infusion :
The content of vial must be dissolved in 100 ml Sodium Chloride 0.9% injection for infusion or 100 ml 5% dextrose injection. The reconstituted solution should be used within 12 hours when omeprazole is dissolved in Sodium Chloride 0.9% injection and within 6 hours when dissolved in 5% dextrose. The reconstituted solution should not be mixed or co-administered in the same infusion set with any other drug. Omep IV infusion should be given as an intravenous infusion over a period of 20-30 minutes or more.
Warning & Precautions:
Impaired renal function : In such cases, dosage adjustment is not required.
Impaired hepatic function : As bioavailability and half-life is increased in patient with impaired hepatic function, the dose requires adjustment with a maximum daily dose of 20 mg.
The elderly : Dosage adjustment is not required in the elderly.
Side effects:
Omep is generally well tolerated. Nausea, diarrhoea, flatulence, abdominal pain, constipation, dizziness and headache have been stated to be generally mild and transient and not requiring a reduction in dosage.
Drug interaction:
Omeprazole can delay the elimination of diazepam, phenytoin and warfarin. There is no evidence of an interaction with theophylline, propranolol or antacid.
Use in special groups:
Use in pregnancy: There is no adequate and well controlled studies on the use of Omeprazole in pregnant women. However, some studies show that it does not cause any harm to the foetus. Omeprazole should be used during pregnancy only if the potential benefit to pregnant women justifies the potential risk to the foetus.
Use in lactation : A decision should be taken to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Paediatric use : Children over 1 year are recommended to use oral Omeprazole.
