  • Patent number: 4657755
    Abstract: Enterically administrable diagnostic compositions for investigating alimentary functions comprising multiple units of a size of at the most 5 mm, preferably between 0.5 and 1.3 mm, in particular between 0.7 and 1.0 mm, each unit comprising a tracer substance binding agent (such as an ion exchange resin) with which a radioactive tracer substance with a half-life of at the most 5 days, in particular .sup.99m Tc, .sup.113m ln, .sup.111 ln and .sup.129 Cs, is associated. The tracer substance binding agent is being formulated with pharmaceutically acceptable excipients, in particular granulating excipients, in such a way that the exposure of the gastrointestinal mucosa to the tracer substance binding agent is reduced and that the units do not disintegrate during the passage through the gastrointestinal tract.
