  • Publication number: 20070202099
    Abstract: The present invention provides an agent for improving the blood stability of an endogenous ligand, which comprises an antibody that has affinity to the mammalian endogenous ligand but substantially does not neutralize the same, and the above-described agent for the prophylaxis and/or treatment for a disease for which an increase in the blood concentration of the endogenous ligand and/or an prolonged blood half-life is prophylactically or therapeutically effective. Provided that the above-described agent is administered alone to a mammal without co-administering the same or substantially the same compound as the endogenous ligand, the blood stability of the endogenous ligand increases and the receptor activity-regulatory action thereof is enhanced.

  • Patent number: 6190702
    Abstract: A sustained-release preparation containing a bioactive polypeptide is prepared using a starting material containing a lyophilized product of an aqueous solution or suspension of the bioactive polypeptide in a non-ionic surfactant. The lyophilized product is dispersed in an oil phase, which further contains a biocompatible, biodegradable polymer.

  • Patent number: 6117455
    Abstract: A sustained-release microcapsule contains an amorphous water-soluble pharmaceutical agent having a particle size of from 1 nm-10 .mu.m and a polymer. The microcapsule is produced by dispersing, in an aqueous phase, a dispersion of from 0.001-90% (w/w) of an amorphous water-soluble pharmaceutical agent in a solution of a polymer having a wt. avg. molecular weight of 2,000-800,000 in an organic solvent to prepare an s/o/w emulsion and subjecting the emulsion to in-water drying.

  • Patent number: 5876756
    Abstract: A microcapsule contains a pharmaceutically effective amorphous water-soluble 2-piperazinone-1-acetic acid compound or salt thereof and a polymer binder and a method of preparing said microcapsule. The microcapsule is produced by dispersing in an aqueous phase a dispersion of the amorphous water-soluble 2-piperazinone-1-acetic acid compound or salt thereof in a solution of a polymer in an organic solvent to give an s/o/w type emulsion and subjecting the emulsion to in-water drying. The sustained-release microcapsule entraps 2-piperazinone-1-acetic acid compound or the salt thereof, as a drug, in high concentration, and in reducing the initial release of the drug, thereby reducing undesirable side effects of the drug.
