Omeprazol Stadapharm (Omeprazole)

Omeprazole acts on the gastric acid secretion pathway and is indicated for several acid‑related conditions.

• Gastro‑oesophageal reflux disease: provides symptomatic relief and promotes healing of erosive esophagitis.
• Peptic ulcer disease: supports ulcer healing and reduces recurrence risk.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion.
• Erosive gastritis: aids mucosal healing and symptom control.
• Prevention of NSAID‑induced ulcer complications: lowers the risk of ulcer formation in at‑risk patients.

• 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 raises gastric pH, allowing damaged mucosa to heal and reducing acid‑related symptoms.

Common Side Effects

• Headache: mild, transient headache reported in clinical use.
• Diarrhea: loose stools occurring in a minority of patients.
• Abdominal pain: mild discomfort or cramping.
• Nausea: occasional feeling of queasiness.
• Flatulence: increased intestinal gas.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Acute interstitial nephritis: inflammation of kidney tissue.
• Clostridioides difficile infection: severe colitis associated with antibiotic use.
• Hypomagnesemia: low serum magnesium levels with prolonged therapy.
• Fracture risk: increased incidence of hip, wrist or spine fractures with long‑term use.
• Stevens‑Johnson syndrome: rare severe skin reaction.
• Liver enzyme elevation: abnormal liver function test results.

Before using Omeprazol Stadapharm, consider the following precautions:

• Assess renal function: dose adjustment may be required in severe renal impairment.
• Review hepatic status: use with caution in patients with liver disease.
• Evaluate long‑term use: monitor for potential bone density loss with extended therapy.
• Pregnancy and lactation: discuss risks and benefits with a healthcare professional.
• Drug interactions: check for concomitant medications that may affect omeprazole metabolism.
• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Omeprazole may interact with several medicines; clinical relevance varies.

Major Interactions (Avoid)

• Clopidogrel: reduced antiplatelet effect, increasing cardiovascular risk.
• Atazanavir: decreased absorption of atazanavir, compromising HIV therapy.
• Methotrexate: increased serum levels, raising toxicity risk.

Moderate Interactions (Monitor Closely)

• Warfarin: potential alteration of INR values.
• Phenytoin: possible reduction in phenyphenyphph.
• Digoxin: modest increase in serum digoxin concentrations.
• Ketoconazole: reduced antifungal efficacy.
