  • Quinolinone derivative pharmaceutical compositon and production method therefor
    Patent number: 7081256
    Abstract: A quinolinone derivative pharmaceutical composition comprising a quinolinone derivative represented by the structural formula (I): wherein the quinolinone derivative is in the form of particles, which have an average particle diameter of 0.5 to 10 ?m and such a particle size distribution that particles having a particle diameter of 15 ?m or less account for 90% or more of the totality of the particles, and also have a fusion enthalpy of 30 J/g or more, and the surface of the particles are coated with a water-soluble composition containing a water-soluble polymer, can quickly dissolve an active ingredient in the digestive tract and is also superior in long-term storage stability.
