Sodium selenite vitamin C injection and preparation method thereof

Abstract

The invention discloses a sodium selenite vitamin C injection and a preparation method thereof. The preparation method comprises the steps that edetate disodium, sodium metabisulfite and seleninic acid are sequentially added into injection water saturated by carbon dioxide, vitamin C is added after the materials are completely dissolved, stirring is conducted so that the vitamin C is completely dissolved, then sodium bicarbonate is added, and the injection water is added finally to get constant volume, so that a mixed solution is obtained; medicinal active carbon is added into the mixed solution, the mixed solution is stirred and filtered to be decarburized, and a filtered filtrate is subjected to refined filtration by using an ultrafiltration membrane; and carbon dioxide gas is continuously guided into the filtrate which is subjected to refined filtration, and a product is potted, sealed and sterilized under existence of carbon dioxide, so that the injection is obtained. The production technology of the preparation method is simple and easy to control; the production efficiency is high by adopting the preparation method, effective components in the injection are stable, and the injection is very suitable for supplementing selenium and vitamin C to domestic animals, and has high popularization and application value.

Description

technical field [0001] The invention relates to sodium selenite vitamin C injection, in particular to a sodium selenite vitamin C injection and a preparation method thereof. Background technique [0002] Vitamin C, also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms with the molecular formula C 6 h 8 o 6 , The molecular weight is 176.1. There are two types of naturally occurring ascorbic acid, L-type and D-type, the latter of which has no biological activity. Vitamin C is a colorless and odorless flaky crystal, easily soluble in water and insoluble in fat solvents. Stable in an acidic environment, it can promote its oxidative destruction when it encounters oxygen, heat, light, and alkaline substances in the air, especially in the presence of oxidase and trace copper, iron and other metal ions.

Problems solved by technology

[0003] With the rapid development of social economy and the advancement of science and technology, whether domestic or wild animals are sick, they can play a good role in the treatment and recovery under the treatment of veterinary drugs. During the growth process of animals, they need to supplement selenium and vitamin C. It is used to prevent infertility caused by vitamin C and selenium deficiency, white muscle disease of young animals, and exudative quality of chicks. In the actual use process, it is inconvenient for livestock to supplement selenium and vitamin C respectively. The existing The production process of sodium selenite vitamin C medicine is relatively complicated and difficult to produce, so a new solution is needed to solve the problem.
