Previous articles have presented a general review of the different types of spheres that can be obtained using a rotary fluidized bed process.1,2 Part I of this study focussed on lipid spheres prepared using hydrogenated castor oil for formulations with low active drug content. The feasibility of the process and the main characteristics of spheres obtained were also studied. In Part II, formulations with higher concentrations of active drug are examined.
