The present invention makes it possible to provide drug-containing coated microparticles for quick-disintegrating oral tablets wherein microparticles containing a drug with an unpleasant taste are coated with a film composed of (1) a pH-independent water-insoluble polymer accounting for 60% or more but less than 80% of the film and (2) a pH-independent water-soluble substance accounting for more than 20% to 40% or less of the film, these microparticles being characterized in that the rate of dissolution of the drug from the drug-containing microparticles is 0% to 10% in one minute and 80% to 100% in 30 minutes, and the average particle diameter is 350 μm or less, in order to realize sufficient control of oral drug dissolution and fast gastrointestinal drug dissolution.
