Niosomes-Based Drug Delivery in Targeting the Brain Tumors Via Nasal Delivery

Targeting tumors has always been a herculean task. Moreover, the presence of blood brain barrier (BBB) acts as a physical barrier and restricts the transportation of therapeutic molecules across the brain. Targeted delivery of the therapeutic payload across the blood brain barrier has gained widespread attention over the past few years. Intranasal route offers delivery to the brain via the trigeminal and olfactory route surpassing BBB. It also offers various other advantages such as surpassing biotransformation, and systemic absorption increasing the efficacy. Over the last few decades, several novel drug delivery systems such as liposomes and other lipid nanoparticles targeting brain, have gained widespread attention. The Niosomes are vesicular nanoparticle flatforms comprised of non-ionic surfactants, which are biodegradable, more stable than liposomes. This current review discusses the potential use of niosomes as a delivery vehicle for targeting brain tumors via the nasal route.
