ABSTRACT:
Conventional spray-drying methods are improved by incorporation of a pressure nozzle and a diffuser plate to improve the flow of drying gas and a drying chamber extension to increase drying time, such improvements leading to the formation of homogeneous solid dispersions of drugs in concentration-enhancing polymers.
