    摘要: Dispersible particles consisting essentially of crystalline NSAID having hydroxypropyl cellulose adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than about 1000 nm. Pharmaceutical compositions containing the particles exhibit unexpectedly reduced gastric irritation following oral administration and/or hastened onset of action.
