106 results about "Omeprazole Sodium" patented technology

The sodium salt form of a benzimidazole with selective and irreversible proton pump inhibitor activity. In the acidic compartment of parietal cells, omeprazole is protonated and converted into the active achiral sulfenamide; the active sulfenamide forms one or more covalent disulfide bonds with the proton pump hydrogen-potassium adenosine triphosphatase (H+/K+ ATPase), thereby inhibiting its activity and the parietal cell secretion of H+ ions into the gastric lumen, the final step in gastric acid production. H+/K+ ATPase is an integral membrane protein of the gastric parietal cell.

Omeprazole sodium composition for injection

The invention provides an omeprazole sodium composition for injection. The omeprazole sodium composition for injection contains omeprazole sodium and ethylene diamine tetraacetic acid; and the weight ratio of the omeprazole sodium to the ethylene diamine tetraacetic acid is 1: (0.02-0.1). The composition is prepared by the following method: 1) preparing a liquid medicine: placing the omeprazole sodium and the ethylene diamine tetraacetic acid into a mixing pot, adding water for injection, stirring to dissolve the omeprazole sodium and the ethylene diamine tetraacetic acid and mixing uniformly, and adjusting the pH value to 11.0 to 12.0 by using sodium hydroxide; 2) processing by a rubber stopper; 3) performing aseptic filtering and packing; and 4) freezing and drying in vacuum so as to obtain the omeprazole sodium composition for injection. For medicaments, such as the omeprazole sodium which is easily reacted with an effusion from a capsule, the omeprazole sodium composition for injection can effectively guarantee that visible foreign matters and insoluble particles of the product meet the requirement of injection at the same time. By the omeprazole sodium composition for injection, the quality level is enhanced obviously, and potential hazards in clinical safe medication use of patients due to unqualified visible foreign matters and insoluble particles can be avoided; and the omeprazole sodium composition for injection has better curative effect and lower clinical side reaction.

The invention discloses an omeprazole sodium freeze-dried powder injection and a preparation method thereof. The omeprazole sodium freeze-dried powder injection contains an active ingredient, namely, omeprazole sodium monohydrate, and auxiliary materials, namely, calcium disodium edetate and sodium hydroxide. The preparation method of the omeprazole sodium freeze-dried powder injection is characterized by comprising the following steps: weighing the calcium disodium edetate of prescription amount and dissolving the calcium disodium edetate in water for injection, stirring, dissolving, and regulating pH value to 10.0-12.0 by using 10% of sodium hydroxide solution; weighing omeprazole sodium of the prescription amount and adding the omeprazole sodium in the mixture, stirring at room temperature for dissolution, supplementing and adding the water for injection to full amount; adding active carbon, stirring at room temperature for decoloration and endotoxin removal, conducting rough filtration to remove carbon firstly, and then conducting refining filtration by using a filter membrane of 0.22 Mum; taking refining filtrate to test intermediate, conducting encapsulation after meeting requirements; and freeze-drying and unboxing, thus obtaining the omeprazole sodium freeze-dried powder injection. The freeze-drying technology of the omeprazole sodium freeze-dried powder injection takes temperature below minus 40 DEG C as pre-freezing temperature; after pre-freezing for at least two hours, sublimation is started, wherein the sublimation temperature is 5-12 DEG C, the sublimation time is over 14 hours; and then drying is conducted for over 2 hours at the temperature of 20-35 DEG C. Unboxing is carried out after a stopper is added and a cover is put in place, thus obtaining the finished product of the omeprazole sodium freeze-dried powder injection.

Preparation method for high-purity esomeprazole sodium

ActiveCN103288801ASolve the prone to titanium complex suspensionSolve the difficulty of splittingOrganic chemistrySodium bicarbonateOmeprazole Sodium
The invention discloses a preparation method for high-purity esomeprazole sodium. The preparation method comprises the steps of: including and splitting esomeprazole sodium and D-(-)-diethyl tartrate, titanium iso-propylate, triethylamine and L-(+)-mandelic acid in the presence of a proper amount of water, and separating to obtain an inclusion complex; dissolving the inclusion complex with ethyl acetate, washing inclusion complex with sodium carbonate water solution, carrying out ammonia hydroxide eluting on an ethyl acetate layer, slowly regulating the pH value to 6-7 with glacial acetic acid, then extracting with dichloromethane, and concentrating to obtain crude esomeprazole free alkali product; carrying out silica gel adsorption and elution on the crude product to obtain a pure esomeprazole free alkali product; and enabling the pure product and the methanol-ethanol-acetonitrile solution of sodium hydroxide to form salt, and then crystallizing with isopropyl ether to obtain the high-purity esomeprazole sodium. According to the preparation method, the difficulties that when inclusion and splitting are carried out, the titanium complex suspension body are difficult to split and the ammonia complex of titanium is difficult to remove can be solved, the industrialization production can be realized, the industrialized production cost is low, the product purity is high, the yield is high, and no harmful gas is generated.
