Omeprazol Zentiva (Omeprazole)

Omeprazole, the active ingredient in Omeprazol Zentiva, is a proton pump inhibitor presented as a tablet for oral use. It reduces stomach acid production and is used to treat conditions such as gastro‑oesophageal reflux disease and peptic ulcer disease in adults.

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

Omeprazol Zentiva is a proton pump inhibitor that acts on gastric acid secretion pathways. It is indicated for several acid‑related disorders: - Gastro‑oesophageal reflux disease (GERD): alleviates heartburn 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 production associated with this rare condition. - Helicobacter pylori eradication regimens: used as part of combination therapy to improve eradication rates. - NSAID‑induced ulcer prophylaxis: lowers the risk of ulcer development in patients requiring long‑term non‑steroidal anti‑inflammatory drugs.

Omeprazol Zentiva is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Headache: mild to moderate intensity. - Diarrhoea: usually self‑limiting. - Nausea or abdominal discomfort: transient gastrointestinal upset. - Flatulence: excess gas formation. - Constipation: occasional bowel habit changes. - Dry mouth: reduced salivary flow.

Serious or Rare Side Effects: - Clostridioides difficile infection: severe colitis in susceptible individuals. - Acute interstitial nephritis: inflammation of kidney interstitium. - Hypomagnesemia: low serum magnesium with prolonged use. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: rare severe skin reactions.

Before initiating therapy with Omeprazol Zentiva, consider the following precautions: - Assess renal function: adjust use in severe renal impairment. - Evaluate hepatic function: use with caution in moderate to severe liver disease. - Review concomitant medications: potential for drug‑drug interactions. - Long‑term use: monitor for vitamin B12 deficiency and bone density loss. - Pregnancy and lactation: weigh benefits against potential risks. - Store at below 25°C: keep in the original container, protect from moisture and direct sunlight.

Omeprazole may interact with several medicines, altering their absorption or metabolism.

Major Interactions (Avoid): - Clopidogrel: reduced antiplatelet effect, increasing cardiovascular risk. - Atazanavir and other protease inhibitors: decreased antiviral efficacy. - Methotrexate (high dose): increased serum levels, risk of toxicity.

Moderate Interactions (Monitor Closely): - Warfarin: potential increase in INR, requiring more frequent monitoring. - Phenytoin: reduced plasma concentrations, may diminish seizure control. - Digoxin: modest rise in serum levels, monitor for toxicity.
