| titleOfInvention | A kind of acetazolamide sodium freeze-dried powder injection and its preparation method and application |
| abstract | The invention discloses acetazolamide sodium freeze-dried powder injection and its preparation method and application. The preparation method comprises the following steps: (1) mixing acetazolamide and water for injection, keeping the temperature at 5-10°C, and then adding acetyl Azolamide is stirred to obtain the medicinal solution; (2) the medicinal solution is sterilized and filtered, and then pre-frozen and dried to obtain acetazolamide sodium freeze-dried powder injection; the specific process of pre-freezing includes: cooling to -40-- 50°C, keep warm for 2-3 hours, then raise the temperature to -15-25°C, keep warm for 2-3 hours, then cool down to -40-50°C, keep warm for 4-5 hours. The quality of the product prepared by the invention is more stable, the total impurity content is less, no organic reagent needs to be added, the safety is higher, and the preparation method is simple. |
