摘要: The present invention provides an improved stabiliser for radiopharmaceuticals which inhibits impurities from being produced by two kinds of decomposition mechanisms and exhibits such an effect that the shelf life of a radiopharmaceutical after its preparation is prolonged as compared with conventional ones. The improvement comprises a combination of an amino-substituted aromatic carboxylic acid or its salt, ester or amide in combination with a diphosphonic acid or its salt.

摘要: A stabilized radiopharmaceutical composition, a kit including same, and a method for making same, where the radiopharmaceutical is (i) susceptible to either reductive degradation or radiolysis and which includes a metal complex of a radionuclide with a ligand, (ii) a first stabilizer for the radiopharmaceutical which is an amino-substituted aromatic carboxylic acid or a salt, ester or amide thereof, and (iii) a second stabilizer for the radiopharmaceutical which is a diphosphonic acid or salt thereof. The first and second stabilizers are present in an amount effective to stabilize the radiopharmaceutical, and the radiopharmaceutical is not a metal complex of the diphosphonic acid.
