Problems solved by technology

However, the drug has a limited therapeutic effect on cardiovascular and cerebrovascular diseases. It was determined by the determination method for the determination of the activity of calf blood deproteinized extract injection in the national drug standard. Enhanced effect, but the stimulation index (SI) activity is only about 1.4

Abstract

The invention provides a muscular amino acids and nucleosides injection medicinal composition and discloses a preparation method of the medicinal composition. The medicinal composition is prepared from a muscular amino acids and nucleosides injection, pentoxifylline, fructose diphosphate sodium and polyethylene glycol. When the medicinal composition is applied in vitro, the liver homogenate breathing activity of a guinea pig can be increased, an activity stimulation index of breathing activity determined by using a Warburgs respirometer is about 4.2, which is far higher than the stimulation index of the liver homogenate breathing activity of the guinea pig during separate testing by using muscular amino acids and nucleosides, the pentoxifyllinum and the fructose diphosphate sodium, and thus, the treating effect on heart cerebrovascular disease is enhanced greatly.

Description

technical field [0001] The invention provides a pharmaceutical composition for carnosine glycoside injection, and also discloses a preparation method of the pharmaceutical composition, which belongs to the technical field of biochemical pharmacy. Background technique [0002] The existing "sarcosaminopeptide glycoside injection" is a prescription drug in my country, which is extracted from the muscle and heart muscle of healthy rabbits and is a sterile aqueous solution containing polypeptides, amino acids, nucleosides and nucleotides. Carnosine glycoside injection has the effects of improving blood circulation disorders, reducing vascular resistance, and increasing myocardial oxygen utilization for cardiovascular system diseases. It can promote the activity of the hematopoietic system, increase the number of white blood cells, increase the elasticity of blood vessels, and prevent arteriosclerosis. Carnosine glycosides are used for brain dysfunction; cerebral apoplexy, cerebr...
