Abstract

Central nervous system disorders significantly affect the lives and health of millions of people worldwide. Despite many therapeutic drugs are available that could potentially target central nervous system disorders, their clinical utility is severely constrained by their inability to cross the blood-brain barrier (BBB). Fortunately, nanotechnology has been advanced to offers a solution to allow drugs reaching the targeted brain regions safely, efficiently, and precisely through nasal drug delivery system (NDDS), bypassing the BBB completely. This strategy can promote the drug accumulated in the targeted brain region, improve drug bioavailability, and minimal side effects and mucociliary clearance effectively. In this review, we elaborate recent advances in the use of lipid-based nanoparticles, involving liposomes, nanoemulsions, nanostructured lipid carriers, and solid lipid nanoparticles. Besides, we particularly introduced the nasal cavity physiological structure, and further summarized the nose-to-brain drug delivery pathways, including olfactory, trigeminal, and blood circulation pathway. Moreover, the mechanism and route of NDDS by various types of nanoparticles are also highlighted.

摘要

中枢神经系统疾病严重影响着全球数百万人的生活和健康。尽管有许多可能针对中枢神经系统疾病的治疗药物,但它们的临床应用受到无法穿过血脑屏障(BBB)的严重限制。幸运的是,纳米技术已经取得进展,通过鼻内给药系统(NDDS)提供了一种解决方案,使药物能够安全、高效且精确地到达目标脑区,完全绕过血脑屏障。这种策略可以促进药物在目标脑区的积累,提高药物生物利用度,并有效减少副作用和黏液纤毛清除。在这篇综述中,我们阐述了基于脂质的纳米颗粒(包括脂质体、纳米乳剂、纳米结构脂质载体和固体脂质纳米颗粒)使用方面的最新进展。此外,我们特别介绍了鼻腔的生理结构,并进一步总结了鼻脑给药途径,包括嗅觉、三叉神经和血液循环途径。此外,还强调了各种类型纳米颗粒的鼻内给药系统的机制和途径。
