13. Dry granulation and compression of spray-dried plant extracts
The purpose of this research was to evaluate the influence of dry granulation parameters on granule and tablet properties of spray-dried extract (SDE) fromMaytenus ilicifolia, which is widely used in Brazil in the treatment of gastric disorders. The compressional behavior of the SDE and granules of the SDE was characterized by Heckel plots. The tablet proper

14. An energy-based population-balance approach to model granule growth and breakage in high-shear wet granulation processes
A mathematical model of high shear wet granulation is proposed, where granule breakage, and not growth, is the dominant process. The energy required for granule breakage is assumed to be provided by the impact of granules between themselves and the granulator parts, and the extent of granule breakage determined by the balance between the impactenergy and the

15. Wet granulation in rotary processor and fluid bed: Comparison of granule and tablet properties
The aim of the present study was to investigate and compare granule and tablet properties of granules prepared by wet granulation in a rotary processor or a conventional fluid bed. For this purpose the working range of selected process variables was determined and a factorial study with 3 factors (equipment type, filler type, and liquid addition rate) and 1

16. Multicenter trial of cadexomer iodine to treat venous stasis ulcer.
In a crossover study designed to judge the efficacy of the topical polymeric starch iodophore, cadexomer iodine, in accelerating the healing of venous stasis ulcers, 75 patients were prospectively randomly assigned to receive either cadexomer iodine or standard treatment. The control treatment consisted of a standard saline wet-to-dry compressive dressing. T
