New modules, new assemblage kits and new assemblies for the controlled release of substances

A module which is destroyed in the presence of water solution, composed of a compressed powdery mixture, the said powdery mixture comprising a matrix building component, suitable to release an optionally included active substance into a surrounding aqueous liquid, and one or more tabletting aids chosen from the group consisting of lubricants, glidants, and anti-adherent agents, the said module being provided with particular male topological features allowing its connection to a corresponding female module, giving raise to an assembly that can be safely handled on industrial scale, wherein, in the composition of the male module, the percentage ratio between the tabletting aid and the matrix building component is comprised between 1:2.5 and 1:999. The module can be employed to convey pharmaceuticals, nutraceuticals, agrochemicals or other active principles to the intended site of action
