Innovative approach for nasal drug delivery system for brain target

The goal of brain drug targeting technology is the delivery therapeutics across blood barrier (BBB), including human BBB. Nose to has received a great deal attention as non- invasive, convenient and reliable system. For systemic targetedadministration drug. various deliveries through some transport pathways, Factor influencing nasal absorption, formulation strategies nose brain, colloidal carriers in system systems. Physiological barriers (BBB) that restricts CNS. Thus intranasal route attracted wide convenient, non-invasive, reliable, safe achieve faster higher level olfactory region by passing barrier. Intranasal administration rapid onset action, no first –pass effect , gastrointestinal degradation lungs toxicity non-invasiveness application also improves bioavailability.
