Omeprazole

Omeprazole, the active ingredient in Omeprazole, is a proton pump inhibitor presented as an oral tablet for oral use. It reduces gastric acid secretion and is used to manage gastro‑oesophageal reflux disease and other acid‑related disorders in adults and, where approved, children.

GNH USA supplies Omeprazole as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Omeprazole is a proton pump inhibitor used to manage conditions caused by excess gastric acid.

Gastro‑oesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of esophageal erosion. Erosive esophagitis: accelerates ulcer healing in the esophagus. Peptic ulcer disease: supports ulcer closure and reduces recurrence. Zollinger‑Ellison syndrome: controls gastric acid hypersecretion.

Omeprazole may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Headache: mild to moderate pain in the head. - Diarrhoea: loose stools occurring intermittently. - Nausea: feeling of stomach upset. - Abdominal pain: discomfort or cramping in the abdomen.

Serious or Rare Side Effects: - Clostridioides difficile infection: severe colitis requiring medical attention. - Hypomagnesemia: low serum magnesium that may cause muscle weakness or cardiac arrhythmia. - Interstitial nephritis: inflammation of kidney interstitium leading to renal impairment.

Before initiating omeprazole therapy, consider the following precautions to ensure safe and effective use. - Assess renal function: dose adjustment may be needed in severe renal impairment. - Long‑term use: monitor for vitamin B12 deficiency and bone density loss. - History of liver disease: use with caution as metabolism occurs hepatically. - Pregnancy and lactation: evaluate risk‑benefit ratio before prescribing. - Drug interactions: review concomitant medications for potential CYP2C19 interactions. - Store at ambient temperature: keep below 25 °C, retain in original container, protect from moisture and light.

Omeprazole can affect the pharmacokinetics of several medicines; review concomitant drugs before prescribing.

Major Interactions (Avoid): - Clopidogrel: reduced antiplatelet effect due to CYP2C19 inhibition. - Atazanavir: decreased absorption of atazanavir leading to therapeutic failure. - Methotrexate (high dose): increased serum levels causing toxicity.

Moderate Interactions (Monitor Closely): - Warfarin: potential increase in INR, monitor coagulation parameters. - Diazepam: increased plasma concentration, observe for sedation. - Digoxin: possible rise in serum digoxin levels, check levels periodically.
