Abstract

The invention relates to lansoprazole composition freeze-dried powder for injection. The lansoprazole composition freeze-dried powder is characterized by comprising lansoprazole used as a main material, meglumine, mannitol, sodium hydrogensulfite and ethylene diamine tetraacetic acid, wherein the proportion of the components is 3:(0.1-1):(1-20):(0.01-0.5):(0.01-0.5); preferably, the proportion is 3:(0.5-1):(10-20):(0.1-0.3):(0.05-0.3); and more preferably, the proportion is 3:1:20:0.2:0.2. The preparation method comprises the following steps of: dissolving the raw material and the auxiliary materials by adding water; regulating the pH value; adding active carbon for decolorizing; filtering for decarburizing; fine filtering by using a filter membrane; sub-packaging; cooling to -50 to -46 DEG C according to a speed of 1-1.2 DEG C/minute; preserving heat and freezing for 3 hours; vacuumizing to 15Pa; uniformly heating up to -22 to -18 DEG C within 7-9 hours and then preserving heat for 1-2 hours; uniformly heating up to 3-7 DEG C within 4-6 hours and then heating up to 40 DEG C within 4 hours; preserving heat and drying for 3 hours; and packaging and storing after inspection.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a proton pump inhibitor drug, more specifically a lansoprazole composition freeze-dried powder for injection. Background technique [0002] Lansoprazole (Lansoprazole) is the second proton pump inhibitor anti-ulcer drug in the world developed by Takeda after Omeprazole (Omeprazole). At the beginning of 1992, this product was officially put on the market in France by Takeda Pharmaceutical Factory and Houde Company (belonging to Roussel Uclaf Company). H on gastric parietal cells + -K + -ATPase. H + It cannot be transported to the stomach, so that the amount of gastric acid in the gastric juice is greatly reduced. It is clinically used for duodenal ulcer, gastric ulcer, reflux esophagitis, Zollinger-Ellison syndrome (gastrinoma) ) treatment, the curative effect is remarkable, and it has inhibitory effect on Helicobacter pylori. Lansoprazole is also known as a proton pump inhib...
