The invention relates to a brain
protein hydrolyzate compound preparation for nerve protection and
nerve repair and a preparation method thereof, belonging to the technical field of
pharmacy. In order to solve the problem that the existing cerebroprotein hydrolyzate easily causes allergies and the oral
utilization rate is low, the present invention provides a compound preparation of cerebroprotein hydrolyzate for
neuroprotection and
nerve repair, and the compound preparation is nasal mucosa administration preparation , containing 0.1-5wt% of cerebroprotein hydrolyzate, and also containing pharmaceutical auxiliary materials and water for injection. Administered through the
nasal cavity, absorbed through the nasal mucosa, it can be absorbed into the brain in the respiratory area and olfactory area of the
nasal cavity, and directly enter the
central nervous system. It has the characteristics of rapid absorption, high
bioavailability, small side effects, and convenient administration. In the present invention, the brain
protein hydrolyzate is made into nano-scale liposomes, so that the active ingredients are more easily absorbed through the mucous membranes, efficiently enter the brain cells and play a role, can maintain the local
drug concentration stably for a long time, reduce the
drug dosage, and are not easy to cause adverse effects on the body. reaction.
