摘要: Objectives The potential of poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) surface modified with octa-arginine (R8) for central nervous system (CNS) delivery was investigated. Methods PLGA NPs containing coumarin-6 or loperamide were using R8 and characterised size, zeta potential, drug loading release. We examined the cellular uptake in Madin-Darby Canine Kidney (MDCK) cells CNS a mouse model following intranasal (i.n.) intravenous (i.v.) administration. Key findings NPs 300–350 nm diameter negative which neutralised on conjugation. Cellular R8-PLGA rapid compared PLGA correlated high antinociceptive effect mice by both i.n. i.v. routes. Little observed reflecting their slow in-vitro cell model. Conclusion This study demonstrates as carriers therapeutic agents to CNS.
