Directly compressible acetaminophen compositions
First Claim
1. A particulate acetaminophen composition capable of being directly compressed, without addition of other components, into a compressed dosage form, said composition comprising, based on the total weight of the dry components of the composition, from 91 to 98 percent by weight acetaminophen and further comprising a fluidizing agent, a binder compound, a disintegrant and a lubricant, said composition comprising free flowing granules, at least a portion of said granules each comprising at least one acetaminophen-rich core, said acetaminophen-rich core comprising acetaminophen and fluidizing agent and having an outer surface, and a binder-rich region supported on at least a portion of the outer surface of the acetaminophen-rich core, said binder-rich region comprising binder compound, wherein, based on the dry weight of the components of the respective acetaminophen-rich core and binder-rich region, the acetaminophen-rich core comprises a relatively higher amount of acetaminophen than the binder-rich region and the binder-rich region comprises a relatively higher amount of binder than the acetaminophen-rich core.

11. A particulate acetaminophen composition capable of being directly compressed, without addition of other components, into a compressed dosage form, said composition comprising from 91 to 98 percent by weight acetaminophen and further comprising a fluidizing agent, a binder compound, a disintegrant and a lubricant, said composition comprising free flowing granules wherein at least a portion of said granules are made by atomizing a binder solution onto a fluidized bed of particles of the acetaminophen and fluidizing agent in a fluidized bed process.
- 13. An acetaminophen composition capable of being directly compressed, without addition of other components, into a compressed dosage form, said composition comprising, based on the total weight of the dry components of the composition, from greater than 95 to 98 percent by weight acetaminophen and further comprising, a combined amount of from about 2 to less than 5 percent by weight, a binder compound, a disintegrant and a lubricant.
- 16. An acetaminophen-containing compressed dosage form, comprising from 91 percent by weight to 98 percent by weight acetaminophen and exhibiting an initial dissolution of greater than 80% according to US Pharmacopeia test method number 711, as applied to acetaminophen.
- 20. An acetaminophen composition capable of being directly compressed into an acetaminophen tablet, said composition comprising from about 80 to about 95 wt % acetaminophen, from about I 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 composition, the composition also comprising a moisture content of up to about 1.5 wt % based on the total weight of the dry components of granulation composition, wherein the composition comprises free flowing granules, said granules comprising an acetaminophen blend and a binder coating the blend, said acetaminophen blend comprising the acetaminophen, the disintegrant, a minor portion of the starch, at least a portion of the fluidizing agent and, optionally, a portion of the lubricant, and said binder comprising polyvinylpyrolidone, the remaining starch and the remaining lubricant.
