Molecular mechanisms of transport of substances across the blood-brain barrie as targets for pharmacological action. Part 2. Modern methods of delivery of pharmacological agents to the central nervous system

Abstract

One of the unresolved problems on the way to improving the pharmacotherapy of CNS diseases is the development and creation of technologies that allow drugs to cross the blood-brain barrier (BBB). The review discusses modern methods of drug delivery to the CNS. The advantages and disadvantages of the main pharmacological strategies for directly overcoming the BBB and an alternative to this are shown. New methods of drug delivery to the brain with damage (physical, chemical, etc.) and without disruption of the blood-brain barrier structure (small molecules, cell-mediated transport, stem cells) are considered. The prospects for the use of artificial nanosized drug transporters are discussed. An alternative strategy of pharmacological action on the CNS structures (intranasal route) is shown to be promising. Possible mechanisms of action of pharmacological agents on CNS structures bypassing the BBB are considered.
