Abstract

The invention discloses a vitamin C sodium squirt cut for injection and a preparation method, and the invention belongs to the field of the medical industry, and the invention relates to a vitamin squirt cut for injection and a preparation method, in particular discloses a vitamin C sodium squirt cut. The vitamin C sodium squirt cut comprises the vitamin C sodium, the anti-oxidant, the anti-oxygen synergistic agent and the water for the injection. The preparation method comprises three procedures which are the preparing of liquid medicine, the removing of the origin of heat and the split charging. Compared with the listed vitamin C sodium preparations, the vitamin C sodium squirt cut has the advantages of low cost and good stability, and the invention can be widely applied in the field of the medical industry.

Description

technical field [0001] The invention relates to a water needle for injection, and more specifically, the invention discloses a water needle for injection of vitamins and a preparation method thereof. Background technique [0002] Vitamin C, also known as ascorbic acid, is a water-soluble vitamin. The main function of vitamin C in the human body is to participate in the metabolism of amino acids, the synthesis of neurotransmitters, the synthesis of collagen and tissue interstitium, reduce the permeability of capillaries, accelerate blood coagulation, stimulate blood coagulation, and promote iron Absorbed in the intestines, it promotes the reduction of blood lipids, increases the resistance to infection, participates in detoxification, and has the effect of antihistamine and preventing the formation of carcinogens (nitrosamines). [0003] The enol chemical structure of vitamin C makes it extremely unstable, easy to oxidize and change color when exposed to air, stable in acidi...
