Document Type and Number:
Japanese Patent JP2004531399
Kind Code:
A
Abstract:
A method is disclosed for producing coated compressed tablets, using at least one upper punch. The upper punch can be a single punch with a hollow shaft containing a movable rod with a tip that is extended or retracted as the rod moves within the shaft. Alternatively, two solid upper punches are used, one with an extended tip and the other with a retracted tip. An upper punch with an extended tip is designed to produce cup-shaped compacts of excipient and/or polymeric tablet coating material, when inserted into the die. Core material is inserted into each cup. Additional coating material is then placed on top of the cup and core, within the die, and compressed with an upper punch with a retracted tip. The method and device of the present invention enables one to produce tablets from poorly compactable substances.
