  • Patent number: 7695735
    Abstract: The invention concerns an improved multiparticulate tablet disintegrating in the mouth in contact with saliva in less than 40 seconds. The invention is characterized in that it is based on particles of coated active principle, said particles having intrinsic compression properties and a mixture of carriers, the proportion of carrier mixture relative to coated active principle particles being 0.4 to 6 parts by weight, the carrier mixture comprising: a disintegrating agent; a diluting soluble agent with binding properties; a lubricant; a permeabilizing agent; and advantageously lubricants, sweeteners, flavoring and coloring agents, the proportion of disintegrating agent and soluble agent relative to the tablet mass being 1 to 15 wt. % for the former and 30 to 90 wt. % for the latter.

  • Patent number: 6660382
    Abstract: The invention concerns a method for making coated granules with masked taste and instant release of the active principle which consists in: first, mixing the constituents of a powder comprising at least the active principle and a granular disintegrating agent; then, granulating the resulting powder, in the presence of a mixture of carriers comprising at least a binding agent capable of binding the particles together to obtain grains; coating the grains formed by spraying a suspension comprising at least a coating agent and a membrane disintegrating agent; finally drying the resulting coated granules.

  • Patent number: 6488964
    Abstract: A process for manufacturing coated particles of &ggr;-aminobutyric acid analogue, whose lactam content by weight relative to the weight of &ggr;-aminobutyric acid analogue is less than 0.5% is disclosed. The process is characterized in that a coating solution of at least one polymer in an organic solvent is sprayed onto the particles of &ggr;-aminobutyric acid analogue.
