Abstract
Today more than 70% of newly discovered drugs (independent from the therapeutic class) showed poor water solubility which may results a serious challenge to the development of new compounds. There are several drug formulation strategies are available to further improve the solubility and / or dissolution rate i.e. solid dispersion technique, self-emulsifying systems or complex formation. These strategies have been successfully used in the past but today nanotechnology has produced a massive impact to meet the needs. Various factors particularly economic, social, public health and environmental benefits have together made nanotechnology based drug delivery systems a very popular one. In this article we have discussed the scope of nanotechnology in the designing of new drug delivery systems.
