“A Review on Different Techniques for Brain Targeting”

Brain is act as a central processing unit in human body as like a in computers. This controls all the body systems under one organ. To reach a drug up to brain, its’ a challenging task. In this review we added techniques that can easily cross the Blood Brain Barrier (BBB). Number of drugs unable to cross BBB easily, so that by using these techniques drug can easily reach to targeted sites. Techniques such as Pro drug, Liposome's, Nanotechnology, Microspheres, Polymeric Micelles and Micro emulsions and Dendrimers are helpful to transfer drug at brain targeted site. Figures in this article can easily explain the basic mechanism of preparation and its hypothetical views to understand the concept of targeted drug delivery system. This article will help on review of these techniques in short manner for students.
