A recent advances in drug delivery to Brain- A review

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 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. Finally, one particular area that is often neglected in brain drug barrier delivery is the influence of aging on the BBB, which is captured in this review based on the limited studies in the literature.
