  • Patent number: 10046019
    Abstract: The present invention relates to inventive novel industrialized method for preparing purified extract containing more abundant active ingredients such as catalpol derivatives from the extract of Pseudolysimachion rotundum var subintegrum than that prepared by the conventional preparation method disclosed in the prior art and the therapeutics or functional health food comprising the purified extract for treating and preventing inflammatory, allergic or asthmatic disease. The purified extract showed more potent anti-inflammatory, anti-allergy and anti-asthma activity than that prepared by the conventional preparation method disclosed in the prior art through various in vivo tests such as inhibition test on the reproduction of eosinophil, the release of immunoglobulin and inflammatory chemokines in plasma and bronchoalveolar fluid as well as the suppression of airway hyperresponsiveness and goblet cell hyperplasia in a OVA-sensitized/challenged mouse model.

  • Publication number: 20170172929
    Abstract: Provided are a sustained-release composition including pregabalin and a pharmaceutically acceptable salt thereof using a gastroretentive drug delivery system (GRDDS), an oral sustained-release formulation using the composition, and a preparation method thereof. In a sustained-release composition according to the present invention and a formulation including the same, a coating compartment including a sugar or a derivative thereof and a plasticizer is introduced onto the outer surface of pregabalin having a less stable structure to ensure stability and to improve compatibility with excipients at the same time, and also to effectively control the release rate. As a result, dosing convenience is improved to provide a gastroretentive drug delivery system having enhanced patient compliance. Therefore, the present invention may exhibit improved therapeutic or prophylactic effects on various neurological diseases, such as neuropathic pain, epilepsy, fibromyalgia syndrome, etc.
