The number of controlled release drug delivery systems have been developed for various routes of administration. Controlled release drug delivery directly targeted to the organ and tissue. The present review describes that activation of modulated drug delivery systems. In modulated drug delivery systems drug release controlled by physical, chemical or biochemical process or facilitated by the energy supplied externally.  In this system drug delivery achieved by based different physic chemical properties like magnetically, osmotically, enzymatic and activation of vapour pressure, nanoparticles etc. The review mainly discussed on the classification and concepts are explained about the various types of modulated drug delivery systems.
