One main challenge in formulation development of pharmaceutical applications is the poor aqueous solubility of many drug substances. This not only leads to limitation of its penetration and dissolution characteristics but also has an immediate effect on its potency as an active pharmaceutical ingredient (API). Creating a solid crystalline suspension (SCS), where both API and matrix are in crystalline condition is one possibility to enhance bioavailability and obtain a stable product.


Spray drying is a common technology in pharmaceutical industry to form dry powder out of a fluid containing a dissolved compound. In this work spray drying combined with an adapted electrostatic precipitator is used to produce SCS in order to enhance the bioavailability of poorly water soluble drugs
