1 results about "Symptomatic relief" patented technology

This invention relates to the field of biomedical materials technology, and more particularly to a flexible patch for treating nervous system diseases and its preparation method. It comprises: a flexible, breathable substrate composed of silk fibroin nanofibers, and drug-loaded nanoparticles loaded within the substrate; the drug-loaded nanoparticles are encapsulated with chitosan and contain levodopa and copper oxide nanoenzymes; the silk fibroin nanofibers are annealed with ethanol to form a controllable degradation structure, achieving self-adhesion and continuous drug release in a humid environment. This patch can simultaneously achieve stable delivery of dopamine and scavenging of reactive oxygen species, thus addressing the motor complications and neurooxidative damage caused by fluctuations in blood drug concentration in traditional Parkinson's disease treatment, achieving a dual synergistic treatment of symptom relief and neuroprotection.
