Abstract

The present invention relates to one kind of thymosin alpha-1 aqua preparation and its preparation process and application in preparing medicine for treating chronic viral hepatitis and other immunological damage diseases. The preparation consists of thymic pentapeptide in 0.1-1000 mg each 0.1-500 ml, medicinal supplementary material, which may be mannitol, polyglycol, cyclodextrin, etc., and water. The preparation process includes compounding, sterilizing, packing, and other steps. The thymosin alpha-1 aqua preparation has high stability, easy preparation and other features, and has wide application foreground in preparing medicine for treating chronic viral hepatitis and other immunological damage diseases.

Description

technical field [0001] The invention relates to the field of medicines and preparations thereof. The core of the invention is to provide a new preparation of thymosin α1, its preparation method and its application in the preparation of medicines for treating chronic viral hepatitis and immune impairment. Background technique [0002] Thymosin α1 (Thymosin-α1, Tα1) is a polypeptide hormone with strong immune activity secreted by the thymus, the central immune organ of the human body. It was first discovered in 1966 and was successfully isolated in 1975. The amino acid sequence and nuclear nucleotide sequence. In the early 1990s, Tα1, which was produced by foreign chemical synthesis methods, entered Phase III human clinical trials and was launched in the United States in 1998. [0003] Tα1 molecule contains 28 amino acids, widely present in the body's thymus epithelial cells, peripheral blood, brain, pituitary, semen, follicular fluid and amniotic fluid. Tα1 can promote the...
