Brain-Targeted Drug Delivery System: A Novel Approach
Abstract
A targeted drug delivery system is based on a technique that continuously administers a predetermined dosage of a therapeutic agent to a sick location of the body. The targeted drug delivery goal is to raise the relative amount of the treatment in the target tissues while lowering it in the non-target tissues. This technique's intrinsic benefit has been reduced drug dose and adverse effects. Drug targeting in the brain is one of the most challenging issues in pharmaceutical research because the blood-brain barrier acts as an impermeable barrier for systemically delivered therapeutics and the brain extracellular matrix contributes to the poor distribution of locally delivered drugs. In the treatment of various Central nervous system (CNS) diseases, general approaches that can improve drug delivery to the brain are of great interest. Drugs are less harmful and more effective when they are administered close to where they would be most effective. Extreme research studies have recently concentrated on the development of fresh strategies for more successfully delivering medications to the brain in response to the shortcomings of the traditional delivery mechanism. This study thoroughly explains the obstacles involved in brain-targeted drug delivery, the process of drug transfer through Blood Brain Barrier, different techniques for brain-targeted drug delivery, and some recent breakthroughs in brain-targeted drug delivery.
