Omeprazole (Omehil) 40mg Lyophilized Powder for Intravenous Injection/Infusion is used to treat conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. The 40mg powder is reconstituted with the included 10ml diluent vial for intravenous administration. As a proton pump inhibitor, it reduces stomach acid production, providing rapid relief from acid-related symptoms. This formulation is typically used in hospital settings for patients who cannot take oral medications.
