The aim of this study was to relate the tableting performance assessed by an instrumented tableting machine to the mechanical properties measured by nanoindentation. Three different polymorphic forms of sulfathiazole were prepared by recrystallization, and the density and X-ray powder diffraction pa

A quantitative method is presented which utilizes differential scanning calorimetry for the determination of sulfathiazole Form I in the presence of sulfathiazole Form 11. Data are included which demonstrate that the method can be utilized to follow the rate of transformation of Form 1 to Form 11. T
The dissolution rates of the two polymorphic forms of sulfathiazole containing polyethylene glycol 4000 were significantly different in water. The effect of agitation on the dissolution rates also was studied. At higher stirring speeds, the dissolution rates of the stable form were affected more tha
The crystal structures of two sulfathiazole complexes, one involving theophylline and the other sulfanilamide, were determined by X-ray diffraction methods. The complexes are 1 : 1 adducts held together by hydrogen bonding. The hydrogen-bonding schemes in the two complexes are quite different. In th
