Nexium (Esomeprazole Magnesium Trihydrate)

Esomeprazole magnesium trihydrate, 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 acid‑related conditions such as gastro‑oesophageal reflux disease and related disorders.

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

Nexium is a proton pump inhibitor indicated for several acid‑related gastrointestinal conditions.

- Gastro‑oesophageal reflux disease (GERD): reduces acid exposure and promotes healing of esophageal irritation. - Erosive oesophagitis: facilitates mucosal healing and symptom relief. - Zollinger‑Ellison syndrome: controls excessive gastric acid production. - NSAID‑induced gastric ulcer prevention: lowers risk of ulcer formation in patients taking NSAIDs. - Helicobacter pylori eradication (in combination therapy): enhances eradication rates when used with antibiotics.

Common Side Effects: - Headache: mild to moderate pain often reported. - Diarrhea: loose stools occurring during treatment. - Nausea: feeling of stomach upset. - Abdominal pain: discomfort or cramps. - Flatulence: increased gas. - Constipation: reduced bowel movements.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis): swelling, rash, difficulty breathing. - Clostridioides difficile infection: severe colitis with watery diarrhea. - Low magnesium levels (hypomagnesemia): muscle cramps, irregular heartbeat. - Bone fractures: increased risk with long‑term use. - Stevens‑Johnson syndrome: serious skin reactions.

Before initiating therapy, consider the following precautions. - Assess renal function: adjust use in severe renal impairment. - Monitor magnesium levels: prolonged therapy may cause hypomagnesemia. - Avoid in known hypersensitivity: discontinue if allergic reaction occurs. - Use caution in patients with liver disease: consider dose adjustments. - Pregnancy and lactation: safety not established, weigh benefits against risks. - Store at room temperature: keep in the original container, protect from moisture.

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

Major Interactions (Avoid): - Ketoconazole: reduced absorption and efficacy of ketoconazole. - Atazanavir: decreased plasma concentrations of atazanavir. - Clopidogrel: reduced activation of clopidogrel, diminishing antiplatelet effect.

Moderate Interactions (Monitor Closely): - Warfarin: possible increase in INR, monitor coagulation. - Digoxin: may increase serum digoxin levels, watch for toxicity. - Methotrexate: potential increase in methotrexate exposure, monitor renal function.
