Abstract

A liquid injection of omeprazole sodium is prepared from omeprazole sodium, Na2EDTA, and polyethanediol-400. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to an omeprazole sodium injection and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Omeprazole (Omeprazole) is a derivative of benzomidazole, the chemical name is (±)-5-methoxy-2 (4-methoxy-3,5-dimethyl-3-pyridyl)methylbenzimidazole has a strong and long-term inhibitory effect on gastric acid secretion in animals and humans, and is widely used at home and abroad Satisfactory results have been achieved in the treatment of peptic ulcer, reflux esophagitis, and gastrinoma. The earliest dosage form of omeprazole on the market was oral preparations, but due to the strong first-pass effect of oral preparations, powder injection and injection dosage forms were developed later. Intravenous injection, directly into the blood, rapid onset of action. Moreover, for patients with severe emergencies, coma, anesthetized patients and other patients who are inconven...
