Abstract

Controlled drug delivery systems have been developed to improve the next staging of the drug in the body. They can play a significant role in targeted drug delivery system in organ or tissue. In Controlled drug delivery system, more than one mechanism may be involved at different stages of drug pharmacokinetics and pharmacodynamics profiling. Some drug delivery systems have been formulated and are being investigated. These types of the system had some advantage over traditional drug delivery system, including short time of drug release protection of breakable drugs and increased patient comfort and compliance. The review underlines the methodology of controlled drug delivery system preparation, their significance, disadvantages, detailed classification and the relevant example wherever required are demonstrated. This review will give an insight to researcher and academician a current update on the topic. In this, a different method and different processes are involved. The paper deals with the stable drug delivery system.
