Abstract

The invention provides a thymopentin injection, comprising a thymopentin as an active component, a plurality of accessories for injection, and certain amount of sterile water for injection, wherein the accessories for injection comprises protective agent, antioxidant and pH regulator. The dosage is as follows: point one to two hundred mg/ml thymopentin, ten to two hundred mg/ml protective agent, point one to ten mg/ml antioxidant, and point five to twenty mg/ml pH regulator. The injection has the advantages of stability while refrigerated at the temperature between two to ten degrees centigrade and long periods of preservation; the purity of the thymopentine remains ninety-nine percent after being stored for twenty-four months; the injection can be stored for six months to twelve months at normal temperature, which significantly facilitates circulation and transportation of drugs, thus ensures excellent stability of the injection.

Description

technical field [0001] The invention relates to a thymopentin injection, which belongs to the field of medicines. Background technique [0002] Thymus is the primary lymphoid epithelial tissue, the central immune organ of the body, and the central organ of T-cell development. In addition to providing a microenvironment required for T-cell development, it can also produce a variety of thymosin hormones. Thymus hormone can induce the differentiation and maturation of various T-cell subsets, and can also enhance the response performance of various T-cells, thereby regulating the function of the entire immune system. Animal thymus (including humans) gradually shrinks and degenerates with age after adulthood, and the secretion of thymus hormones also gradually decreases, and it shrinks significantly in old age, with only a small amount of cortex and medulla remaining. Therefore, some people think that senile infectious diseases, tumors, A high incidence of autoimmune disease is ...
