Novel Methods on Improving Drugs Across the Blood-brain Tumor Barrier into the Tumor / 中国药学杂志

ABSTRACT

The treatment of brain tumors is greatly limited due to the presence of the blood-brain barrier/blood-brain tumor barrier. In recent years, the application of some new technologies has improved the permeability of the blood-brain barrier and improved the curative effect. However, malignant tumors cause the gap between the tight connections to be larger, and capillary leakage appears. Another barrier to glioma chemotherapy, the blood-brain tumor barrier, is formed among the leaky blood-brain barrier, the neovascular and malignant brain tumor tissues, which greatly limits the penetration and accumulation of drugs into the tumor. The author has reviewed relevant information at home and abroad in recent years, and then analyzed and summarized. This article not only analyzed the structural characteristics of the blood-brain tumor barrier, but also reviewed the technologies and methods which had been proved to improve the drug across the blood-brain tumor barrier such as drug combination, novel formulation technology, physical technology and biotechnology, aiming to explore the comprehensive treatment of brain tumors.
