Omeprazol Hennig (Omeprazole)

Omeprazol Hennig is a proton pump inhibitor that acts on the gastric acid secretion pathway. It is indicated for several acid‑related disorders:

• Gastro‑oesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of the oesophageal lining.
• Peptic ulcer disease: supports ulcer healing and reduces risk of recurrence.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion associated with the condition.

• Omeprazole irreversibly binds to the H+/K+‑ATPase enzyme (the gastric proton pump) on the secretory surface of parietal cells, inhibiting the final step of acid production. This suppression of gastric acid secretion lowers gastric pH, allowing damaged mucosa to heal and reducing acid‑related symptoms.

Adverse reactions to Omeprazole may range from mild to severe.

Common Side Effects

• Headache: mild, transient headache reported by some patients.
• Diarrhoea: loose stools occurring during early treatment.
• Nausea: occasional feeling of queasiness.
• Abdominal pain: mild discomfort in the stomach area.
• Flatulence: increased gas formation.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Clostridioides difficile infection: severe colitis linked to altered gut flora.
• Acute interstitial nephritis: sudden kidney inflammation.
• Stevens‑Johnson syndrome: rare severe skin reaction.
• Hypersensitivity reactions: rash, itching, or swelling.
• Liver enzyme elevation: abnormal liver function tests.
• Fracture risk: possible reduction in bone mineral density with long‑term use.

When using Omeprazole, certain precautions should be observed:

• Assess renal function: adjust use in patients with severe kidney impairment.
• Review cardiovascular risk: consider long‑term use implications for bone health.
• Monitor for infections: be aware of increased risk of gastrointestinal infections.
• Evaluate pregnancy status: use only if clearly needed.
• Assess hepatic function: dose adjustment may be required in severe liver disease.
• Store below 25°C: keep in the original packaging, protect from moisture and light.

Omeprazole may interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.
