DEFINITION

Classification: 424/1.25

Dissolving or eluting from solid or gel matrix (e.g., capsule, tablet):

(under subclass 1.11) Subject matter in which the composition comprises a physical form which includes a reticulated network of solid or gel material from which the radionuclide

or intended radionuclide is eluted, or is released by dissolution of the network.

(1) Note. Proper for placement in this subclass are compositions in which the radionuclide or intended radionuclide component is entrapped and compositions in which the radionuclide or intended radionuclide component is attached (bonded, chelated, complexed) to the matrix.

1.29+, for those particulate carriers which dissolve, bio-assimilate, or bio-degrade (e.g., in the host) only after the diagnostic or therapeutic process has been accomplished.
