  • Bioabsorbable pharmaceutical formulation
    Patent number: 7342048
    Abstract: A bioabsorbable release-sustaining pharmaceutical formulation using a biodegradable release-sustaining base material which can prevent an effective component drug from being released too rapidly just after administration of the formulation and then allow continued release of the drug for at least one month at a defined rate, is provided. For the biodegradable release-sustaining base material, a lactic acid-glycolic acid copolymer (PLGA) with an adjusted distribution in molecular weight is used.
    Type: Grant
    Filed: April 25, 2006
    Date of Patent: March 11, 2008
    Assignee: Nipro Corporation
    Inventors: Tatsuaki Miyaji, Makoto Sato, Tamaki Murayama, Yohei Hoashi, Hisae Saito, Takao Okada, Yukari Imamura, Yoshimichi Fujiyama

  • Stabilized aqueous preparation for injection
    Publication number: 20060058312
    Abstract: The present invention provides a stabilized aqueous preparation for injection containing 5-formyl-(6S)-tetrahydrofolic acid or a pharmacologically acceptable salt thereof as an active ingredient and a method of stabilizing 5-formyl-(6S)-tetrahydrofolic acid or a pharmacologically acceptable salt thereof. An aqueous preparation containing 5-formyl-(6S)-tetrahydrofolic acid or a pharmacologically acceptable salt thereof shows extremely excellent preservation stability in the presence of a pH regulator and an antioxidant.
