▎ 摘　　要

NOVELTY - A medicine sustained and controlled release platform system comprises double nanocomposite structure comprising electrostatic spinning nanofiber film and nanoparticle/ball/sheet/crystal. The drug sustained and controlled release platform system is drug sustained and controlled release system compounded by drug-loaded nanoparticle/sphere/wafer/crystal and drug-loaded nanofiber membrane through specific process and technology, for oral administration or in vitro administration, such as oral administration, mucous membrane administration, wound dressing, and transdermal administration. USE - The medicine sustained and controlled release platform system is useful for oral administration or in vitro administration, such as oral administration, mucous membrane administration, wound dressing, and transdermal administration. ADVANTAGE - The system not only further improves the specific surface area and drug loading rate of the drug-loading system, but also prolongs the continuous administration time of the primary administration; reduces the administration times of the patient. It can also adjust he medicine release speed, and improve the medicine accuracy. It fully exerts the synergistic effect of the medicine, fully exerts the pharmaceutical sustained and controlled release function of the preparation material, so as to achieve more ideal treatment effect.
