The goal of pharmaceutical preparation investigation is to utilize to the full of every bang-up properties while overcoming as many another as manageable unsought properties of existent operational drugs & formed drug molecules. The choice of accepted applied science & technology in the formulation is habitually favored to maintain a time table and success rate requirements in industry. But in numerous cases new excipients for formulation or delivery technologies are required to formulate coveted clinically significant improvements, for differentiation in the market and to those fortifying for industrial protection. This is important aspect influencing development and industrialization is the scale-up in the production of formulation excipients and delivery systems. A methodical consideration of the processes taking place at a molecular stage is crucial for the logical development of solid dispersions. The parameters like manufacturing certain thermodynamic properties of BCS class II drugs, factors that affects stability of the system, physicochemical properties of drug in solid dispersion, mechanisms responsible solubility & dissolution rate enhancement as well as mechanisms to make the system stable, for choosing the right polymeric carrier & the solubilizing formation techniques all these should be well thought-out before forming solid dispersion. Systematically done workings come out to be indispensable for enhancing potential of many existing & outdated copious BCS class 2/4 drugs as well as new chemical entities.
