Abstract

The invention relates to the field of medicinal preparations and discloses a fat-soluble vitamin freeze-dried injection and a preparation method thereof, so as to solve the problems of clarity and stability of the fat-soluble vitamin for injection in the prior art. The freeze-dried injection contains vitamin A palmitate, vitamin D2, vitamin E, vitamin K1, ethanol, polysorbate 80, tween-20, mannitol and sodium hydroxide. The clarity and stability of the fat-soluble vitamin freeze-dried injection disclosed by the invention are greatly improved, and the medicine risk is reduced.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a fat-soluble vitamin freeze-dried injection and a preparation method thereof. Background technique [0002] Fat-soluble vitamins are essential nutrients for the human body. Clinically, critically ill patients need to be supplemented to maintain normal daily metabolism. Since fat-soluble vitamins are insoluble in water and have low bioavailability when administered orally, they are generally prepared as injections. [0003] Fat-soluble vitamins include vitamin A, vitamin D2, vitamin E, and vitamin K1. Except for vitamin E, which is relatively stable, the other three components are unstable to light, heat, and air, and are easily degraded. There are stability issues in both. In terms of storage and transportation, freeze-dried preparations have more advantages; secondly, due to the high temperature process of sterilization, the water needle will be degraded to a certai...
