    摘要： The described agglomeration of drug microparticles blended with excipient microparticles is a technique for the size enlargement of micronized products that could be damaged by granulation or compaction techniques. These agglomerates can be used as oral prompt or delayed-release dosage forms administered as they are or dispersed in a liquid. The composition and quantity of the excipient microparticles resulted to be the crucial factors for the agglomerate quality. Therefore, adjusting the content of surface-active agent between 8-20%, of the excipient microparticles it is possible to agglomerate microparticles of drugs that could not be agglomerated per se. Increasing the surfactant concentration in the spray-dried excipient microparticles or increasing the fraction of these excipient microparticles in the blend, the agglomeration was improved. The spray drying technique concentrates the surface-active agent on the microparticle surface. By tumbling, the surface-active agent present on microparticles excipient surface was spread to fill the inter-particle interstices of drug particles giving rise to more resistant agglomerates. This phenomenon occurred also by vibration; the production in this case was quicker.

    摘要： 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.
