    摘要: A process for preparing preparations for oral administration which do not have a bitter taste which comprises either dissolving a bitter taste-masking substance at a high concentration in a solvent to be used for dissolving or suspending a bitter active ingredient and adding the active ingredient to the resulting solution followed by kneading, or kneading a solution or suspension in which a bitter active ingredient has been dissolved or suspended with the bitter taste-masking substance, adding silicic acid anhydride to the resulting kneaded substance to form a powder and granulating the powder using a solution of the bitter taste-masking substance in a fluidized bed granulator.

    摘要: This invention relates to an antibiotic preparation comprising a macrolide antibiotic, which is highly stabilized against an acidic solution or acidic substance because of the presence of a polymer component incorporated with the macrolide antibiotic by specific solvent treatment, and to a process for the production of such antibiotic preparation. The antibiotic preparation of this invention overcomes the defect of macrolide antibiotics that they are easily decomposed upon contact with an acidic solution or acidic substance.
