| titleOfInvention | Preparation method for lansoprazole for injection |
| abstract | The invention relates to a preparation method for lansoprazole for injection. The preparation method comprises the following steps: preparing 431 ml of a 0.2 N sodium hydroxide solution, weighing 30 g of micronized lansoprazole, adding the micronized lansoprazole to the prepared 0.2 N sodium hydroxide solution under nitrogen gas protection, and stirring until the micronized lansoprazole is completely dissolved; weighing 10 g of meglumine, adding 100 ml of medical injection water, and stirring until the meglumine is completely dissolved to obtain an intermediate solution 2; and weighing 60 g of mannitol and 2 g of disodium edentate, adding 800 ml of medical injection water, and stirring until the mannitol and the disodium edentate are completely dissolved to obtain an intermediate solution 3. A purpose of the present invention is to provide a preparation method for lansoprazole for injection, wherein the preparation method has characteristics of simple and safe operation, reasonable process conditions, low process cost, short production time, high production efficiency, no three waste pollution, equipment saving, energy saving, labor saving and field saving, and the produced drug liquid has a good clarity. |
