Cerebroprotein hydrolysate oral solution is more commonly used in adult and pediatric neurology, and it has precise efficacy, less adverse effects, and better efficacy for brain cell damage caused by various reasons. Brain cells are sensitive to hypoxia and ischemia, and once they are damaged, they are poorly repaired. The mechanism of action of the drug mainly includes: it is a peptide-ergic neurotrophic drug unique to the brain, which can pass the blood-brain barrier and can act on the central nervous system in various ways to regulate and improve the metabolism of neurons, and has the protective ability against hypoxia. Moreover, it can promote the synthesis of synapses and proteins in the brain, which is the reason for the wide range of clinical applications. The main diseases that can be used for clinical treatment are: congenital cerebral hypoplasia, central nervous system infection, senile dementia, sequelae of craniocerebral trauma, sequelae of cerebrovascular accident, cerebral palsy, pediatric nuclear jaundice, hypoxic-ischemic encephalopathy, hypoglycemic brain injury and other diseases.
