Xeldrin® is a preparation of Omeprazole, which is a proton pump inhibitor, weak base in nature and is concentrated and converted to the active form in the highly acidic environment of the intracellular canaliculi within the parietal cell, where it inhibits the enzyme H+/K+ - ATPase, the acid pump. This effect on the final step of the gastric acid formation process is dose-dependent and provides for highly effective inhibition of both basal acid secretion and stimulated acid secretion, irrespective of the stimulus.

Xeldrin® IV Injection
Prophylaxis of Acid Aspiration: Xeldrin® 40 mg IV injection to be given slowly, one hour before surgery.
Duodenal Ulcer, Gastric Ulcer, Reflux Esophagi/is: Xeldrin® 40 mg IV injection once daily.
Zollinger-Ellison Syndrome: Initial dose is 60 mg once daily. Higher daily doses may be required and the dose should be adjusted individually. When dose exceed 60 mg daily, the dose should be divided and given twice daily.
Children: There is limited experience with Omeprazole for intravenous use in children.
Elderly: Dosage adjustment is not necessary.
Patients with impaired hepatic function
As bioavailability and plasma half-life is increased in patients with impaired hepatic function, the dose requires adjustment and a daily dose of 10 to 20 mg may be sufficient.
Patients with renal impairment
No dose adjustment is necessary in patients with impaired renal function.
Method of administration for injection
Xeldrin® 40 mg IV injection should be given as a slow intravenous injection. Reconstitute the contents in vial with 10 ml supplied water for injection BP (No other solvent should be used). Discoloration may occur if incorrect reconstitution technique is used. After reconstitution the injection should be given slowly over a period of at least 2.5 minutes at a maximum rate of 4 ml per minute. Use only freshly prepared solution. Reconstituted solution is stable for up to 4 hours at 25°C.
Infusion
For IV infusion, dissolve the content of one vial of Xeldrin® 40 mg IV injection with 100 ml 0.9% Sodium Chloride solution or 5% Dextrose solution to make a solution of 0.4 mg/ml of Omeprazole approximately. The resultant infusion should be given intravenously over a period of 20-30 minutes or more. The solution should be used within 12 hours when Omeprazole is dissolved in 0.9% Sodium Chloride and within 6 hours when dissolved in 5% Dextrose. After reconstitution, start the infusion immediately. The constituted solution should not be mixed or co-administered in the same infusion set with any other drug.
Pregnancy: Not known to be harmful.
Lactation (Breastfeeding): Present in milk but not known to be harmful.
Omeprazole may alleviate symptoms and delay diagnosis of gastric carcinoma.
There is no known contraindication to the use of Omeprazole.
Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin drugs that are metabolized by oxidation in the liver. Monitoring and dose adjustment is recommended for the patients receiving warfarin and phenytoin in addition to Omeprazole. There is no evidence of an interaction of Omeprazole with theophylline, propranolol and antacids.
