Abstract

The invention relates to a preparation method for cerebroprotein hydrolysate freeze-dried injection for injection, which comprises the following steps: weighing 5000 volume of cerebroprotein hydrolysate solution; adding 4-10 mass/volume% of skeleton agent into the solution in the aseptic condition, and adjusting the range of Ph to be 6.9-7.5; collecting filter liquor after 0.45mum bacilli-eliminated filtration; filing and drying, wherein the drying time is sequentially 5 hours in the temperature of minus 40 DEG C, 4 hours in the temperature of minus 40 DEG C to minus 15 DEG C, 4 hours in the temperature of minus 15 DEG C to 5 DEG C, 2 hours in the temperature of minus 5 DEG C to 5 DEG C, 3 hours in the temperature of 5 DEG C to 40 DEG C, and 10 hours in the temperature of 40 DEG C; and thedrying time is totally 28 hours. The product prepared by the preparation method is stable and controllable; and the operational technique is simple.

Description

technical field [0001] The invention relates to a preparation method of biological medicine, in particular to a preparation method of cerebroprotein hydrolyzate freeze-dried powder for injection. Background technique [0002] Cerebroprotein hydrolyzate, as an active brain polypeptide substance extracted from healthy and fresh animal brain tissue by multi-enzyme hydrolysis, contains a variety of essential amino acids for human brain and important elements such as cephalin, lecithin, and peptide nerve growth factor. It acts on the central nervous system in various ways, regulates and improves the metabolism of neurons, promotes the formation of synapses, induces neuron differentiation, and further protects nerve cells from various ischemia and neurotoxin damage. It can pass through the blood-brain barrier, promote protein synthesis in the brain, affect the respiratory chain, protect against hypoxia, and improve energy metabolism in the brain. Activates adenylyl cyclase to cat...
