  • Publication number: 20100028426
    Abstract: A time-specific delayed/pulsatile release dosage form which comprises: a core comprising at least one active principle and at least one disintegrating agent; a sealing layer surrounding the core essentially consisting of one or more water soluble or water insoluble pH independent polymers; an outer coating essentially consisting of one or more hydrophilic pH independent polymers; wherein: the at least one disintegrating agent is present in amounts of 1-20% by weight and the at least one active principle is present in amounts of 1-80% by weight, with respect to the core; the sealing layer accounts for 0.1-10% by weight, with respect to the core; the outer coating accounts for 5-500% by weight, with respect to the core. These coated cores are capable of ensuring the immediate release of the active principle after a pre-defined lag time, independently of physiological pH variations occurring in the gastro-intestinal tract of mammals.

  • Patent number: 7160938
    Abstract: A lubricating/detaching/fluidifying additive composition for organic polymers is described, comprising a saturated hydrocarbon having from 25 to 35 carbon atoms with at least three side substituents consisting of a methyl group, combined with at least one polysiloxane polymer having a molecular weight higher than 500,000. The use of this composition or single hydrocarbon component as lubricating/detaching/fluidifying additive for organic polymers, is also described, together with a polymeric composition containing additives, comprising an organic polymer and the additive composition. The use according to the present invention is particularly advantageous as it is universal (the same additive for all organic polymers, regardless of their formulation); it allows the use of high viscosity/high M.W. polymers (suitable for extrusion), also in injection moulding, and enables the additive to be applied externally to the polymer.
