Nexium (Esomeprazole)

Esomeprazole, the active ingredient in Nexium, is a proton pump inhibitor presented as an oral dosage form for oral use. It reduces gastric acid production and is prescribed for conditions such as gastro‑oesophageal reflux disease and related acid‑related disorders. GNH USA supplies Nexium as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Esomeprazole is a proton pump inhibitor used to manage acid‑related gastrointestinal conditions. - Gastro‑oesophageal reflux disease (GERD): alleviates heartburn and regurgitation by decreasing stomach acidity. - Erosive esophagitis: promotes healing of acid‑induced esophageal lesions. - Helicobacter pylori eradication: used in combination therapy to improve bacterial clearance. - Zollinger‑Ellison syndrome: controls excessive gastric acid secretion associated with gastrin‑producing tumors.

Adverse reactions may occur with any medication and should be monitored by a healthcare professional.

Common Side Effects: - Headache: mild to moderate intensity. - Diarrhoea: usually transient. - Nausea or abdominal discomfort. - Flatulence or bloating. - Constipation: occasional. - Dry mouth: occasional.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis, angioedema). - Clostridioides difficile‑associated diarrhoea. - Acute interstitial nephritis or renal impairment. - Low magnesium levels (hypomagnesemia). - Bone fractures with long‑term use. - Liver enzyme elevations indicating possible hepatitis.

Before initiating therapy, consider the following safety measures. - Assess renal function: dose adjustment may be required in severe impairment. - Evaluate hepatic status: use with caution in patients with liver disease. - Review allergy history: avoid if known hypersensitivity to esomeprazole or other PPIs. - Monitor for infection: prolonged use can increase risk of gastrointestinal infections. - Pregnancy and lactation: discuss potential risks with a prescriber. - Store at ambient temperature: keep below 25°C in the original packaging, protect from moisture and direct sunlight.

Esomeprazole can alter the absorption or metabolism of several medicines.

Major Interactions (Avoid): - Ketoconazole, itraconazole, atazanavir: reduced antifungal/antiviral efficacy due to increased gastric pH. - Clopidogrel: decreased antiplatelet effect via CYP2C19 inhibition. - Warfarin: potential increase in anticoagulant effect.

Moderate Interactions (Monitor Closely): - Digoxin: higher serum concentrations may occur. - Methotrexate: reduced clearance can raise toxicity risk. - Diazepam and other benzodiazepines: increased plasma levels. - Phenytoin: altered metabolism may affect seizure control.
