<p>A directly compressible ultra fine acetaminophen granulation composition capable of being directly compressed into an acetaminophen tablet comprises from about 85 to about 95 wt % acetaminophen, from about 1 to about 4 wt % essentially water-insoluble tablet/capsule disintegrant, from about 0.5 to about 5.0 wt % polyvinylpyrrolidone, from about 0.5 to about 5.0 wt % totally pregelatinized starch, about 0.25 to about 3.0 wt % of a fluidizing agent, from about 0.25 to about 3.0 wt % of a lubricant, and optionally up to about 10 wt % of a co-active ingredient, the weight percents being based on the total weight of the dry components of the granulation composition, the granulation also comprising a moisture content of up to about 1.5 wt % based on the total weight of the dry components of granulation composition. This directly compressible acetaminophen granulation composition is produced by granulation in a top spray fluid bed granulator employing heated fluidization air, a first heated binder solution of a major portion of the polyvinylpyrrolidone dissolved in water, and a second binder solution of a minor portion of the polyvinylpyrrolidone and a portion of the totally pregelatinized starch and optionally a lubricant.</p> |
