  • Modular systems for the controlled release of a substance with space and time control
    Patent number: 8545883
    Abstract: An innovative pharmaceutical form for controlled drug release relates to systems obtained by the assembly of individual release modules, of which the capacity to release the drug in time and in space depends on the way in which the modules have been assembled. The modular structure offers high reproducibility of manufacture and flexibility of release.
    Type: Grant
