Nexium (Esomeprazole)

Esomeprazole, the active ingredient in Nexium, is a proton pump inhibitor presented as an intravenous solution for intravenous use. It treats gastro‑oesophageal reflux disease, erosive oesophagitis, NSAID‑induced gastric ulcer and Zollinger‑Ellison syndrome in adult patients.

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

Esomeprazole (Nexium) is a proton pump inhibitor used to manage acid‑related gastrointestinal conditions.

- Gastro‑oesophageal reflux disease (GERD): reduces esophageal acid exposure and relieves heartburn and regurgitation. - Erosive oesophagitis: promotes healing of damaged esophageal mucosa. - NSAID‑induced gastric ulcer: protects the gastric lining by lowering acid secretion. - Zollinger‑Ellison syndrome: controls excessive gastric acid production associated with gastrin‑secreting tumors.

Common Side Effects: - Headache: mild to moderate pain often occurring shortly after infusion. - Diarrhoea: loose stools that may be self‑limiting. - Nausea: feeling of queasiness without vomiting. - Abdominal pain: discomfort or cramping in the stomach area.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction with rash, swelling, and breathing difficulty. - Clostridioides difficile infection: severe colitis presenting with watery diarrhoea. - Hypomagnesemia: low serum magnesium that can cause muscle cramps or arrhythmia. - Hepatic enzyme elevation: increased liver transaminases indicating possible liver stress.

Before initiating therapy, consider patient‑specific factors and monitor appropriately. - Renal impairment: assess renal function and monitor for accumulation. - Hepatic impairment: use with caution; monitor liver enzymes. - Pregnancy: safety not established; weigh benefits against potential risks. - Drug interactions: review concomitant medications for possible interactions. - Long‑term use: monitor serum magnesium and vitamin B12 levels. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze.

Esomeprazole may interact with several medicines; review patient medication lists.

Major Interactions (Avoid): - Clopidogrel: reduced antiplatelet effect, increasing cardiovascular risk. - Atazanavir: decreased absorption, leading to sub‑therapeutic levels. - Methotrexate (high dose): increased toxicity due to reduced clearance. - Ketoconazole: markedly decreased antifungal absorption.

Moderate Interactions (Monitor Closely): - Warfarin: potential increase in INR, requiring closer coagulation monitoring. - Digoxin: possible rise in serum digoxin concentrations. - Diazepam: enhanced sedation due to higher plasma levels. - Calcium carbonate: may reduce esomeprazole absorption, affecting efficacy.
