Particle and Coating Tech/Rapid Polymeric Coating Technique Using Powder Layering in Rotor

The development of a powder coating methodology including the utilization of a new type of fluidized bed apparatus is reported. Several different polymer systems were tried and
compared to solvent-based techniques using acetaminophen as a model drug. Process parameters are described and the performance of the polymer coating system relative to solvent based coating system is compared.
