Tablets obtained by binding a powdery mixture (5a, 5) containing at least the principal agent (2), a highly wettable saccharide (3) and a disintegrating agent (4) by using a binder (6, 6c) containing a highly wettable saccharide to give granules (1a, 1b, 1c), and then compression-molding these granules (1a, 1b, 1c). A process for producing tablets which comprises the step of mixing a powdery mixture (5a, 5), which has been prepared by homogeneously mixing at least the principal agent (2), highly wettable saccharide grains (3) and disintegrating agent grains (4), with air to give a fluidized bed; the step of producing granules (1a, 1b, 1c) containing the principal agent by spraying an aqueous solution of a binder (6, 6c) and a highly wettable saccharide (3) dissolved therein onto the above-mentioned fluidized bed of the powdery mixture (5, 5a) followed by spraying; and the step of compression-molding these granules (1a, 1b, 1c) containing the principal agent (2).

L'invention se rapporte à des comprimés fabriqués par liaison d'un mélange pulvérulent (5a, 5) contenant au moins l'agent principal (2), un saccharide fortement mouillable (3) et un agent de désintégration (4). Pour ce faire, on utilise un liant (6, 6c) contenant un saccharide fortement mouillable de manière à obtenir des granules (1a, 1b, 1c) puis on forme lesdits granules (1a, 1b, 1c) par moulage par compression.
