  • Publication number: 20140154330
    Abstract: Disclosed are spherical particles of clopidogrel bisulfate and a pharmaceutical composition containing the same. The spherical particles can be used for preparing a tablet having sufficient hardness through direct compression, by improving unformulable properties of clopidogrel bisulfate such as compressibility, flowability and strong surface electrostatic charges, reduce a problem in compressing tablets such as weight variation, sticking, etc., and the risk of form conversion, and improve physiochemical stability. Therefore, the spherical particles of the present invention may be used as therapeutics for arteriosclerosis, stroke, myocardial infarction and atherosclerosis.

  • Publication number: 20080292696
    Abstract: The present invention relates to an enteric, sustained-release tablet comprising paroxetine or a hydrates or anhydrides of a pharmaceutically acceptable salt thereof as active substance, more particularly to a tablet prepared by coating a sustained-release tablet core containing paroxetine with an enteric polymer, wherein the interaction between the tablet core and the enteric coating layer is minimized to enable constant drug release without regard to the residence time of the tablet in the stomach.

  • Publication number: 20080132533
    Abstract: This invention relates to a solid dispersion formulation comprising tacrolimus and enteric polymer. The solid dispersion formulation may contribute to better stability of tacrolimus preparation under high temperature and humidity condition through reduced recrystallization rate of tacrolimus. In addition, the solid dispersion formulation releases tacrolimus immediately in aqueous media and elevated solubility level maintains for certain period of time and that way the formulation may also enhance the bioavailability and oral absorption rate of tacrolimus.
