Omeprazolo Eg Stada (Omeprazole)

Omeprazolo Eg Stada is a proton‑pump inhibitor that acts on the gastric acid secretion pathway.

• Gastro‑esophageal reflux disease (GERD): alleviates heartburn and promotes healing of the esophageal lining.
• Peptic ulcer disease: supports ulcer healing and reduces recurrence risk.
• Zollinger‑Ellison syndrome: controls excessive gastric acid production associated with the condition.

• Omeprazole inhibits the H+/K+‑ATPase enzyme (the gastric proton pump) located in the parietal cells of the stomach lining. By binding covalently to this pump, it blocks the final step of acid secretion, leading to a sustained reduction in gastric acidity and an environment that facilitates mucosal healing.

Adverse reactions to omeprazole vary in frequency and severity.

Common Side Effects

• Headache: mild to moderate discomfort.
• Diarrhea: loose, watery stools.
• Nausea: feeling of stomach upset.
• Abdominal pain: cramping or discomfort in the stomach area.
• Flatulence: excess gas.
• Constipation: difficulty passing stools.

Serious or Rare Side Effects

• Severe allergic reaction: rash, itching, swelling, dizziness, or trouble breathing.
• Clostridioides difficile infection: persistent diarrhea with abdominal pain.
• Low magnesium levels: muscle cramps, irregular heartbeat, or seizures.
• Fracture risk: increased likelihood of hip, wrist, or spine fractures with long‑term use.
• Liver enzyme elevation: signs of liver dysfunction detected in blood tests.
• Acute interstitial nephritis: kidney inflammation presenting with fever, rash, and urinary changes.

When using Omeprazolo Eg Stada, consider the following safety measures:

• Assess renal function: adjust use if significant impairment exists.
• Evaluate hepatic function: use with caution in patients with liver disease.
• Review long‑term therapy: periodic reassessment is advised for chronic users.
• Monitor for vitamin B12 deficiency: prolonged acid suppression may affect absorption.
• Pregnancy and lactation: weigh benefits against potential risks; consult a healthcare professional.
• Store at ambient temperature: keep below 25°C, in the original container, protected from moisture.

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

Major Interactions (Avoid)

• Clopidogrel: omeprazole reduces its antiplatelet activation.
• Atazanavir: decreased absorption due to higher gastric pH.
• HIV protease inhibitors (e.g., nelfinavir): lowered plasma concentrations.

Moderate Interactions (Monitor Closely)

• Warfarin: potential increase in INR.
• Phenytoin: may lower phenytoin levels.
• Methotrexate: reduced renal clearance can raise toxicity risk.
• Digoxin: possible increase in serum concentrations.
• Iron supplements: diminished absorption when taken concurrently.
