  • Patent number: 6316026
    Abstract: A method and an apparatus are adapted to manufacture a tablet capable of quick disintegration in the oral cavity that has a sufficiently large porosity and can be disintegrated in the oral cavity in a very short period of time, typically between 3 and 5 seconds. A tablet manufactured by means of such a method and such an apparatus also constitutes part of the present invention. The method for manufacturing a tablet capable of quickly disintegration in the oral cavity comprises steps of punching a tablet out of a pharmaceutical composition containing one or more than one medicinal agents and one or more than one water-soluble saccharides under pressure between 0.20 and 0.01 t/cm2 and shaping the tablet by moisturizing and drying it, while transferring it without causing it to drop, said tablet having a porosity between 20 and 40%.
