The Overall prevalence rate for CNS pathology has demonstrated that approximately 1.5 billion people under going from disorders of central nervous system. The most distressing fact about delivery of drugs to the CNS is the presence of blood brain barrier that have a tendency to impair the drug distribution and denotes the major impediment for the development of CNS drugs. Neuropeptides and many drugs which are hydrophilic in nature, possibly will encompass the intricacy while passing the blood brain barrier. The net amount of delivered drug (medicinal agent) and its capability to gain access to the pertinent target sites are the main considering points for CNS drug development. In order to distribute the drugs into the CNS via passing the blood brain barrier, many new emerging approaches have been developed for example Magnetic drug targeting, chemical delivery Systems, Drug carrier systems (antibodies, liposomes or Nanoparticles). Among drug carrier system, Nanoparticles exhibit an impressive attention in the field of targeted drug delivery system because of possessing solid colloidal particles with a size range between 1- 1000nm. Gradual drug release reduced peripheral toxicity and potential totarget specific brain sites by crossing the blood brain barrier are major benefits contributed by Nanoparticles. In this review we will discuss the methodologies for targeting the brain site.

Abstract


The Overall prevalence rate for CNS pathology has demonstrated that approximately 1.5 billion people under going from disorders of central nervous system. The most distressing fact about delivery of drugs to the CNS is the presence of blood brain barrier that have a tendency to impair the drug distribution and denotes the major impediment for the development of CNS drugs. Neuropeptides and many drugs which are hydrophilic in nature, possibly will encompass the intricacy while passing the blood brain barrier. The net amount of delivered drug (medicinal agent) and its capability to gain access to the pertinent target sites are the main considering points for CNS drug development. In order to distribute the drugs into the CNS via passing the blood brain barrier, many new emerging approaches have been developed for example Magnetic drug targeting, chemical delivery Systems, Drug carrier systems (antibodies, liposomes or Nanoparticles). Among drug carrier system, Nanoparticles exhibit an impressive attention in the field of targeted drug delivery system because of possessing solid colloidal particles with a size range between 1- 1000nm. Gradual drug release reduced peripheral toxicity and potential totarget specific brain sites by crossing the blood brain barrier are major benefits contributed by Nanoparticles. In this review we will discuss the methodologies for targeting the brain site.
