摘要:
A pulsating vibration air generation means (1) in which wave height, frequency and wave shape of the pulsating vibration air can be optionally modified and such pulsating vibration air can be periodically and continuously emitted. The pulsating vibration air generation means (1) comprises a valve chamber (5) with an inlet port (2) and an outlet port (3) where a valve plug (7) and a valve seat (4) with a control opening (4a) are provided and a cam mechanism which moves valve plug (7) to open or close the opening (4a) of the valve seat (4), whereby positive or negative pulsating vibration air is emitted from the outlet port (3) while pressurized air is supplied into the inlet port (2) or air is sucked from the inlet port (2).

A process for the production of tablets essentially composed of an active ingredient, a filler and a lubricant (L), which comprises the step of preparing a molding material (m) essentially consisting of the active ingredient, the filler and part (Wc) of the lubricant (L), the step of applying the rest (We) of the lubricant (L) on the surfaces (3s, 4s) of punches (3, 4) and the surface (1s) of a die (1), and the step of tabletting the material (m) by using the punches (3, 4) and die (1) whose surfaces (3s, 4s, 1s) are coated with the lubricant (L).
摘要:
A coating device for powder material, capable of applying powder material onto the lower surfaces of a plurality of upper mallets, upper surfaces of a plurality of lower mallets and inner peripheral wall surfaces of a plurality of mortars in a tablet making machine. Air-mixed powder material is sprayed onto the material-contacting surfaces of lower mallets from the lower-mallet powder-material spraying ports of a lower-mallet powder-material spray unit to apply powder material to the material-contacting surfaces of the lower mallets, and air-mixed powder material sprayed from the lower-mallet powder-material spraying ports is sprayed, along the rotation paths of a plurality of upper mallets of an upper-mallet powder-material spray unit, from upper-mallet powder-material spraying ports provided to extend longer than the lower-mallet powder-material spraying ports to spray powder material onto the material-contacting surfaces of the upper mallets, that are hard to be coated with powder material due to a gravity problem, while the upper mallets move from the proximal ends to the distal ends of the upper-mallet powder-material spraying ports.
摘要:
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).
摘要:
A tablet comprising sugar alcohol or saccaride having an average particle diameter of not more than 30 mu m, an active ingredient, and a disintegrant. It is an intraorally rapidly disintegrable tablet which does not require a special pharmaceutical manufacturing technology and can be simply and easily produced by a normal equipment.
摘要:
A tablet manufacturing method comprising a step of providing molding materials including effective ingredients, a step of applying a lubricant to the surfaces of a mortar and a mallow housed in a spray room in advance by generating air pulsation wave and spraying the lubricant within the room and a step of compressing the molding materials using the lubricant-coated mortar and mallow.

摘要:
Tablets containing a drug affected in contact with a lubricating agent, wherein the tablets contain no lubricating agent in it, the inner structure of the tablets comprises a compressed mixture of the drug with a filler, and a lubricating agent is located on the tablet surface. A process for producing tablets which involves the step of mixing a drug affected in contact with a lubricating agent with a filler to give a mixture; the step of mixing a lubricating agent powder and dispersing with air-pulsating wave under positive pressure; the step of spraying the lubricating agent powder, which has been dispersed by the above air-pulsating wave under positive pressure, onto the bottom face of the upper pestle, the top face of the lower pestle and the side face of the mortar of a tabletting machine so as to coat the bottom face of the upper pestle, the top face of the lower pestle and the side face of the mortar with the powder; and the step of compression-molding the above mixture by using the pestles and mortar coated at each surface with the lubricating agent.
