Abstract:
The present invention discloses nerve growth factor composition and an injection powder comprising the following components: 10 μg/mL-100 μg/mL of a nerve growth factor; 10 mg/mL-80 mg/mL of disaccharide stabilizer; 0 mg/mL-30 mg/mL of an amino acid stabilizer; 0.01 mg/mL-1 mg/mL of surfactant, 10 mg/mL-50 mg/mL of a supporting agent; a pH buffer for maintaining the nerve growth factor composition at 6.0-7.4, and solvent being water. The nerve growth factor composition and the injection powder can avoid the potential risk resulting from the virus of other unknown components carried in albumin by using a disaccharide or a combination of a disaccharide and an amino acid instead of albumin as a stabilizer; not only have protective effect on mNGF, but also can ensure the stability of hNGF and rhNGF in the preparation, transportation and storage processes, and have better medication safety and quality control.

Claim (Index 5):
The nerve growth factor composition according to  claim 1 , wherein the amino acid stabilizer is at least one of alanine, glycine, arginine, glutamic acid, histidine and isoleucine.
