  • Publication number: 20110077195
    Abstract: An effective liquid preparation achieves high bioavailability (BA) of physiologically active peptides or proteins, including ghrelins, that are administered as drugs. Also provided is a method for improving the BA of physiologically active peptides or proteins, including ghrelins, that are subcutaneously injected in aqueous solutions. The liquid preparation contains: a physiologically active peptide or protein, such as ghrelins, as an active ingredient; an acid solution including one or a combination of two or more selected form the group consisting of acetic acid, lactic acid, phosphoric acid, glycine, citric acid, hydrochloric acid, propionic acid, butyric acid, benzoic acid and salts thereof; an alcohol; and a polar organic liquid including one or a combination of two or more selected from the group consisting of N-methyl-2-pyrrolidone, dimethylformamide, dimethylsulfoxide and methylparaben.

  • Patent number: 5910416
    Abstract: Adrenomedullin which is a novel peptide having a hypotensive effect; proadrenomedullin N-terminal 20 peptide (proAM-N20) corresponding to an amino acid sequence of an N-terminus of proadrenomedullin, having a catecholamine secretion inhibitory effect; proadrenomedullin N-terminal 10-20 peptide (proAM-N(10-20)) having a Na channel inhibitory effect, and a gene encoding these peptides are provided. In addition, according to the present invention, these peptides in a sample containing adrenomdullin or proAM-N20 in an unknown amount can be quantified by using an antibody against adrenomedullin, proAM-N20, or its fragment.
