Abstract

Sulfadiazine was granulated by the fluidized-bed (Uni-Glatt), as well as by the conventional massing and screening (Wet granulation) methods. The effects of binder concentration and its type on the mechanical properties of granules and their corresponding tablets, as well as on disintegration time and drug content were studied. It was found that the fluidized bed method was an efficient with all tested binders to produce superior granules. However, disintegration time of the corresponding tablets was found to be increased markedly and was greatly affected by the type and the concentration of the binder. Some suggestions to overcome this problem are stated.
