Polyvinyl acetate is described in the literature as a matrix former in theophylline sustained-release tablets obtained by hot-melt extrusion [646]. In a similar way spray-dried PVAc/Povidone can be applied for the production of tablets and pellets using its excellent flowability. In this case the pulverization of polyvinyl acetate by cryogenic grinding can be avoided and the mixture of the active ingredient with the excipients are applied directly to the melt extruder. [Pg.117]

The solution is atomized in a cryogenic medium, e.g., liquid nitrogen, to freeze sprayed droplets. The dispersion of frozen droplets in the cryogenic medium is taken out and dried in a freeze dryer under vacuum. A typical flow sheet is shown in Figure 10.51. Because of the long freeze-drying time required, this process is... [Pg.270]
