Before the development of any pharmaceutical formulation, a drug's various physiochemical properties have to be determined to facilitate the process of development of new drug candidates. Preformulation studies were reported to play a very important role to anticipate formulation problems and identify a logical path in the formulation of liquid, semisolid, and solid dosage forms. The optimization of each process unit is necessary in order to assure a robust formulation. In general, as the development of new drugs progresses an expansion of …
