Pharmacology

Omeprazole, a substituted benzimidazole, works as a stomach acid secretion inhibitor. It blocks the hydrogen-potassium-adenosine triphosphatase (H+/K+ ATPase) enzyme system in the gastric parietal cell, inhibiting gastric acid secretion. After oral treatment, the antisecretory effect begins within one hour, peaks within two hours, and secretion suppression lasts up to 72 hours. Secretory activity gradually recovers when the medicine is stopped, usually within 3 to 5 days.

IV Injection-

Prophylaxis of acid aspiration: Omeprazole 40 mg to be given slowly (over a period of 5 minutes) as an intravenous injection, one hour before surgery.

Duodenal ulcer, gastric ulcer or reflux oesophagitis: In patients with duodenal ulcer, gastric ulcer or reflux oesophagitis where oral medication is inappropriate, Omeprazole IV 40 mg once daily is recommended.

Zollinger- Ellison syndrome (ZES): In patients with Zollinger-Ellison Syndrome the recommended initial dose of Omeprazole given intravenously is 60 mg daily. Higher daily doses may be required and the dose should be adjusted individually. When doses exceed 60 mg daily, the dose should be divided & given twice daily.

Direction for use of IV Injection: Omeprazole lyophilized powder and water for injection is for intravenous administration only and must not be given by any other route. Omeprazole IV injection should be given as a slow intravenous injection. The solution for IV injection is obtained by adding 10 ml water for injection to the vial containing powder. After reconstitution the injection should be given slowly over a period of at least 2 to 5 minutes at a maximum rate of 4 ml/minute. Use only freshly prepared solution. The solution should be used within 4 hours of reconstitution.

Direction for use of IV Infusion: Omeprazole IV infusion should be given as an intravenous infusion over a period of 20-30 minutes or more. The contents of one vial must be dissolved in 100 ml saline for infusion or 100 ml 5% Dextrose for infusion. The solution should be used within 12 hours when

Omeprazole is dissolved in saline 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.

 

Interaction

Diazepam, warfarin, and phenytoin can all be delayed by omeprazole. When Omeprazole is added to the treatment, it may be required to reduce the amount of warfarin or phenytoin. Omeprazole does not appear to interact with theophylline, propranolol, or antacids.

 

Contraindications

Cosec 20 is not recommended for patients who have a known hypersensitivity to any of the formulation's ingredients.

 

Side effects

Omeprazole is a medication that is generally well tolerated. Nausea, stomach colic, paresthesia, dizziness, and headache have all been reported to be minor and temporary, requiring no dosage adjustments.

 

Pregnancy & Lactation

Omeprazole is classified as a pregnancy category C by the US Food and Drug Administration. However, three prospective epidemiological studies show that Omeprazole has no negative impact on pregnancy or the health of the fetus/newborn kid. There is no information on Omeprazole's transit into breast milk or its effects on the newborn. If the usage of Omeprazole is regarded necessary, breast-feeding should be terminated.

 

Precautions & Warnings

When a stomach ulcer is suspected, the risk of a gastric cancer should be ruled out first, as therapy with Omeprazole may mask the symptoms and delay diagnosis.
