Nexium (Esomeprazole)

Esomeprazole, the active ingredient in Nexium, is a proton pump inhibitor presented as an oral tablet for oral use. It reduces gastric acid secretion and is used to treat acid‑related disorders such as gastro‑oesophageal reflux disease, erosive oesophagitis 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.

Nexium (esomeprazole) is a proton pump inhibitor indicated for several acid‑related conditions.

- Gastro‑oesophageal reflux disease (GERD): provides relief of heartburn and promotes healing of the oesophageal lining. - Erosive oesophagitis: accelerates mucosal healing and reduces recurrence of lesions. - Helicobacter pylori eradication (in combination therapy): enhances the effectiveness of antibiotic regimens. - Zollinger‑Ellison syndrome: controls excessive gastric acid production associated with gastrin‑secreting tumours.

Common side effects are generally mild and transient.

Common Side Effects: - Headache: mild to moderate intensity. - Diarrhoea: watery stools, usually self‑limiting. - Nausea: occasional feeling of queasiness. - Abdominal pain: cramp‑like discomfort. - Flatulence: increased intestinal gas. - Constipation: reduced bowel movements.

Serious or Rare Side Effects: - Clostridioides difficile infection: severe colitis risk. - Severe allergic reactions: anaphylaxis, angioedema. - Stevens‑Johnson syndrome/toxic epidermal necrolysis: skin blistering. - Liver enzyme elevation: hepatitis signs. - Hypomagnesemia: low magnesium levels with prolonged use. - Bone fracture risk: decreased calcium absorption over long term.

Before initiating therapy, consider the following precautions.

- Renal function assessment: adjust use in severe impairment. - Hepatic function evaluation: monitor in patients with liver disease. - Drug interaction review: check for CYP2C19 substrates. - Long‑term use monitoring: assess for vitamin B12 deficiency and bone health. - Hypersensitivity check: avoid if known allergy to esomeprazole or other PPIs. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Esomeprazole may affect the pharmacokinetics of several medicines.

Major Interactions (Avoid): - Clopidogrel: reduced antiplatelet effect. - Atazanavir: decreased antiviral absorption. - HIV protease inhibitors (e.g., ritonavir): altered plasma concentrations.

Moderate Interactions (Monitor Closely): - Digoxin: increased serum levels. - Phenytoin: reduced anticonvulsant efficacy. - Ketoconazole: decreased antifungal absorption.
