5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
task currently important.
Regulation of nanoparticles.
Size : 10~100nm (EPR effect)
Coating PEG polymer
Why nanoparticles?
1) It can deliver a larger quantity of drugs with better safety.
2) Easy to attach targeting ligands.
3) It is enough size to deliver multi-drugs.
4) Can regulate releasing of drug particles.
5) Can avoid multidrug resistance through cell-surface protein pump.
모든 형태의 방출조설 system의 궁극적인 목표는 약품을 투여하고자하는 목표 조직에 약품을 특정한 시간동안 조절된 속도로서 전달하고자하는 것이다. 이와 같은 목적을 달성하기 위해서는 여러 가지 parameter에 대한 깊은 이해가 필요하며 방출조절 system을 개발하는데 있어서 고려되어야할 몇 가지 사
