Medical composition for injection

Abstract

The invention discloses a medical composition for injection, which is characterized by comprising the following components by weight part: 5-20 parts of vitamin B1, 1-10 parts of riboflavin sodium phosphate (metered by riboflavin), 100-300 parts of vitamin C, 100-500 parts of excipient, 0.1-1 part of complexing agent and a pH regulating agent. Compared with a vitamin C injection on the market, the medical composition has low content of related substances and high content of effective constituents; and proved by high-temperature, high-humidity and strong-light tests, the medical composition has better stability.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a compound vitamin C pharmaceutical composition for injection. Background technique [0002] The so-called "nutritional supplements" include carbohydrates, proteins, fats, vitamins, minerals and other five essential nutrients for the body. These substances bypass the liver and directly enter the body circulation. It can meet the needs of maintaining nutrition. Providing nutrients parenterally can reduce the secretion and peristalsis of the digestive tract, keep the digestive tract in a state of rest, and help the recovery or healing of diseases. Sometimes, although complete self-healing cannot be achieved, after active nutritional support, the general condition is greatly improved, which greatly increases the chance of successful further treatment and reduces the mortality rate sharply. In short bowel syndrome, it can play a role in maintaining nutrition until the intestinal tr...

Problems solved by technology

With the improvement of people's living standards, the clinical application of total parenteral nutrition is becoming more and more widespread, and the market potential is huge. Compound vitamin C injection has been on the market in Japan for several years, but vitamin C has poor stability in aqueous solution. Therefore, pharmaceutical developers hope to study Powder injections or freeze-dried powder injections replace injections, but in the process of researching powder injections or freeze-dried powder injections, the problem of stability of raw materials has also been encountered. Therefore, research on compound vitamin C powder injections or freeze-dried powders has been going on. unable to succeed
