  • Method of tagging excipients with 99M technetium
    Patent number: 4057615
    Abstract: A method of using .sup.99m technetium for tagging excipients in medical diagnosis by scintigraphy comprises mixing, in an aqueous solution of alkali-metal pertechnetate, an excipient and a reducing agent in the form of a complex, which complex is such that the association constant of the anion with reduced technetium is less than the association constant of the excipient with reduced technetium, thereby forming a radio-pharmaceutical substance which is a complex between the excipient and .sup.99m technetium.
