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 secretion and is used to treat 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, ensuring quality and regulatory compliance.

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

- Gastro‑oesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of the esophageal lining. - Erosive esophagitis: reduces acid exposure to allow ulcer healing. - NSAID‑induced gastric ulcer: protects the gastric mucosa from ulcer formation. - Zollinger‑Ellison syndrome: controls excessive gastric acid secretion. - Helicobacter pylori eradication: used in combination therapy to improve eradication rates.

Common Side Effects: - Headache: mild to moderate pain often reported. - Diarrhea: loose stools occurring during treatment. - Nausea: feeling of queasiness without vomiting. - Abdominal pain: discomfort in the stomach area. - Flatulence: increased intestinal gas. - Constipation: difficulty passing stools.

Serious or Rare Side Effects: - Clostridioides difficile infection: severe colitis risk. - Severe allergic reactions: including anaphylaxis. - Stevens‑Johnson syndrome: rare skin and mucous membrane disorder. - Liver enzyme elevation: potential hepatic involvement. - Hypomagnesemia: low magnesium levels with prolonged use. - Increased fracture risk: possible bone density reduction with long‑term therapy.

Before initiating therapy, consider patient‑specific factors and monitor appropriately. - Renal function assessment: adjust use in severe impairment. - Hepatic disease evaluation: use caution in moderate to severe liver disease. - Magnesium monitoring: check levels during prolonged treatment. - Drug hypersensitivity review: avoid if known allergy to esomeprazole or other PPIs. - Store at below 25°C: keep in the original pack, protect from moisture.

Esomeprazole may alter the absorption or metabolism of several medicines.

Major Interactions (Avoid): - Rilpivirine: reduced antiviral exposure. - Atazanavir: decreased absorption requiring acidic environment. - Clopidogrel: diminished activation leading to reduced antiplatelet effect.

Moderate Interactions (Monitor Closely): - Warfarin: possible increase in INR. - Digoxin: elevated serum concentrations. - Methotrexate: reduced clearance increasing toxicity risk. - HIV protease inhibitors (e.g., darunavir): altered plasma levels. - Ketoconazole: decreased absorption requiring dosage adjustment.
