Problems solved by technology

[0008] Although inosine sodium chloride injection has been listed in the 2010 edition of the "Chinese Pharmacopoeia", it is often found that individual batches of products still have oxidation phenomena such as yellowing and yellowing within the validity period. This uncertain quality problem has not only caused the production Enterprises have caused great losses; and it is very likely to cause drug safety to clinical patients

Abstract

The invention discloses a method for preparing inosine and its composition injection, which is composed of raw material inosine, sodium chloride, glycine as an auxiliary material, and water for injection. 100ml of the composition contains 0.6wt% inosine and 0.9wt% chloride Sodium and 0.15wt%‑0.25wt% glycine; it is a large-volume injection made of inosine and pharmaceutically acceptable auxiliary materials that can be used for injection and has stable quality, and is used for leukopenia and thrombocytopenia caused by various reasons, Adjuvant treatment of heart failure, angina pectoris, hepatitis, etc. It can also be used as an adjuvant treatment for optic atrophy and central retinitis. In addition, it relates to the preparation of a composition injection of polygeline peptide and inosine, which is a large-capacity injection made of polygeline peptide, inosine and pharmaceutically acceptable adjuvants and has stable quality, and is used for acute isovolumetric injections. Blood thinning improves microcirculation and prevents tissue damage from ischemia and hypoxia.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to the preparation of an injection of inosine and its composition. Background technique [0002] inosine. Chemical name: 9-D-ribose hypoxanthine, molecular formula: C 10 H 12 N 4 O 5 , molecular weight: 268.23, chemical structure: [0003] [0004] Inosine is a hypoadenosine compound, a normal component of the human body and a precursor of adenine, which can directly enter the body cells through the cell membrane and participate in nucleic acid metabolism, energy metabolism and protein synthesis in the body. [0005] Inosine can activate the pyruvate oxidase system, increase the activity of coenzyme A, activate liver function, and make tissue cells in a state of low energy and hypoxia continue to metabolize, which is helpful for the recovery of damaged liver cell function. And participate in human energy metabolism and protein synthesis. [0006] Inosine...
