Each vial contains:
- Omeprazole Sodium (equivalent to 40 mg Omeprazole)

Omeprazole Sodium for Injection is indicated for:
- Gastroesophageal Reflux Disease (GERD) with esophagitis

- Zollinger-Ellison Syndrome and other conditions associated with pathological hypersecretion of gastric acid
- Prevention of stress ulcers in critically ill patients
- Upper gastrointestinal bleeding (adjunct therapy)
Dosage & Administration:
Recommended Dosage (Adults Only):
- GERD with Esophagitis: 40 mg IV once daily for 7-10 days
- Peptic Ulcer Disease: 40 mg IV once daily for 7-10 days
- Zollinger-Ellison Syndrome: Initial dose 60 mg IV once daily, then adjust based on acid secretion (up to 120 mg/day in divided doses)
- Prevention of Stress Ulcers: 40 mg IV once daily
- Upper Gastrointestinal Bleeding: 40 mg IV every 12 hours for the first 72 hours, followed by oral therapy
