Pharmaceutical Sciences

\ Pharmaceutics is the study of relationships between per formulation, pharmaceutical formulation, delivery, disposition and clinical response. The inherent instability nature of a new drug will alter its desired form into undesired form when presented in a suitable dosage form with the excipients upon storage. In early days this process was confined only for assessing few characteristics, but today this process is being considered as a formulation strategy and hence tremendous technological advancement has been achieved in this field which enables us to save time and money through planned management system and hence impacts .Use of glorious statistical software even based on artificial neural networking are made the task of preformulating and optimization process easier. With the increasing number of novel and specialized compounds being developed, a "one size fits all" approach to drug formulation and delivery is no longer optimal, necessitating the consideration of formulations unique to each drug.

\ Revenues within the global generics market reached an estimated value of $265 b in 2012, showing a growth of 9.3% throughout the year. The contribution of generics is approximately 20% of overall international pharmaceutical market. The utilization of generic in terms of volume is higher in the US and lower in Japan, 89% and 24% respectively.
