Controlled drug delivery systems

Abstract

Conventional systems, which are widely used and known as sustained release, have the disadvantages such as harming the human body and short duration of action due to the fact that the drug goes out of the therapeutic zone. These systems can cause toxic effects by causing drug accumulation in the body. With the developing technology, controlled drug release systems have started to take the place of conventional systems. The aim of controlled drug release systems is to provide the treatment of diseases by sending the right drug in the right amount and time to the target area. Controlled drug release systems do not require excessive doses and do not cause drug accumulation in the body due to their long-term therapeutic properties. In this study, the benefits, applications and types of controlled drug release systems were investigated and presented.
