Lanex

Omeprazole, the active ingredient in Lanex, is a proton pump inhibitor presented as an oral dosage form for oral use. It reduces gastric acid secretion and is used to treat conditions such as gastro‑oesophageal reflux disease, peptic ulcer disease and ulcer prophylaxis in adults. GNH USA supplies Lanex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Omeprazole is a proton pump inhibitor that acts on the gastric acid‑secreting pathway to manage acid‑related disorders. - Gastro‑oesophageal reflux disease (GERD): reduces acid exposure, relieving heartburn and regurgitation. - Peptic ulcer disease: promotes ulcer healing by lowering gastric acidity. - NSAID‑induced ulcer prophylaxis: prevents ulcer formation in patients taking non‑steroidal anti‑inflammatory drugs. - Helicobacter pylori eradication (in combination therapy): enhances the effectiveness of antibiotic regimens by creating a less acidic gastric environment.

Omeprazole is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Headache: mild to moderate intensity. - Diarrhoea: loose stools, usually transient. - Abdominal pain: discomfort or cramping. - Nausea: feeling of sickness. - Flatulence: increased gas. - Constipation: reduced bowel movements.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis): rash, swelling, difficulty breathing. - Clostridioides difficile infection: persistent diarrhoea, abdominal pain. - Low magnesium (hypomagnesemia): muscle weakness, irregular heartbeat. - Vitamin B12 deficiency: fatigue, neuropathy with long‑term use. - Stevens‑Johnson syndrome: skin blistering and mucosal involvement. - Elevated liver enzymes: jaundice, dark urine.

Before initiating therapy, consider the following safety measures. - Assess renal function: adjust use in severe impairment. - Monitor for infection risk: especially C. difficile colitis. - Evaluate electrolytes: watch magnesium and calcium levels. - Consider long‑term use: increased risk of bone fracture. - Store at room temperature: keep in the original container, protect from moisture and light.

Omeprazole may alter the pharmacokinetics of several medicines.

Major Interactions (Avoid): - Clopidogrel: reduced antiplatelet effect. - Atazanavir: decreased absorption, loss of antiviral activity. - Ketoconazole: markedly reduced absorption. - Warfarin: possible increase in INR and bleeding risk. - High‑dose methotrexate: increased toxicity.

Moderate Interactions (Monitor Closely): - Digoxin: increased serum concentrations. - Diazepam: elevated levels, enhanced sedation. - Phenytoin: decreased plasma levels. - Iron salts: reduced oral absorption. - Calcium carbonate: decreased omeprazole absorption.
