Abstract

Blood-brain barrier (BBB) together with enzymes restricts the entry of substances for maintaining the internal milieu of the brain. Because of the presence of multiple endogenous transporters, BBB allows a selective entry of nutrients and minerals across it and limits the entry of foreign substances like drugs as well as neuropharmaceutical agents. This makes the CNS treatment ineffective. The conventional drug delivery systems which release drug into general circulation fail to deliver drugs effectively to brain and is therefore not very useful in treating certain diseases that affect CNS including Alzheimer's disease, dementia, Parkinson's disease, mood disorder, AIDS, viral and bacterial meningitis. Therefore there is a need to develop and design approaches which specifically target to brain in a better and effective way. The present review enlightens about several novel approaches including nanotechnology based approach like nanoparticles, liposomes, antibody mediated delivery approach and application of genomics in brain drug targeting that would give an insight to the researchers, academia and industrialists.

摘要

血脑屏障 (BBB) 与酶一起限制物质进入,以维持大脑的内部环境。由于存在多种内源性转运体,BBB 允许选择性地进入营养物质和矿物质,同时限制药物和神经药物等外来物质的进入。这使得中枢神经系统 (CNS) 的治疗效果不佳。传统的药物输送系统将药物释放到全身循环中,无法将药物有效地输送到大脑,因此在治疗某些影响 CNS 的疾病方面并不是非常有用,包括阿尔茨海默病、痴呆、帕金森病、情绪障碍、艾滋病、病毒和细菌性脑膜炎。因此,需要开发和设计专门针对大脑的方法,以更好、更有效地治疗。本综述介绍了几种新的方法,包括基于纳米技术的方法,如纳米粒子、脂质体、抗体介导的递药方法以及基因组学在脑靶向药物中的应用,这将为研究人员、学术界和工业界提供深入的了解。
