  The present invention relates to a volatilization-preventing solid preparation, and more specifically, a chemical container that is produced by sublimation of the drug while containing the drug that is volatile or its decomposition product is volatile. The present invention relates to a volatilization-preventing solid preparation that suppresses generation of unpleasant odor from the whisker and the preparation, and a method for producing the same.

  In general, the solid preparation is hermetically stored in a medicine container such as a glass bottle. However, depending on the nature of the drug contained in the solid preparation, it is known that the value of the product is reduced when the product is stored.

  For example, a sublimable drug such as ibuprofen has a problem that when stored in a closed container such as a glass bottle, the inner wall of the glass bottle becomes cloudy (whisker) over time, reducing the commercial value. As the method for preventing whisker of ibuprofen, a method of storing a solid preparation containing ibuprofen and polyvinylpyrrolidone, magnesium oxide and sodium bicarbonate in a closed system (Patent Document 1), a solid preparation containing ibuprofen, A method of storing a desiccant in a closed system (Patent Document 2), and a method of coating 5 to 60% of the sugar coating weight of the uncoated tablet with a sugar coating liquid containing a saccharide, an excipient and a binder (Patent Document 3). ), And a method of applying undercoating with saccharides (Patent Document 4) has been reported.

As a method for preventing whisker such as caffeine, a method of coexisting a caffeine-containing preparation, a beard crystal-forming drug-containing preparation and charcoal, silicic anhydride or (and) montmorillonite (Patent Documents 5 and 6), a sublimation drug (Patent Document 7), a method of containing β-1,4 glucan powder having a specific size and specific surface area in a pharmaceutical formulation that easily generates whiskers (Patent Document 7) Patent Document 8) and a method of adding an antacid to caffeine (Patent Document 9) have been reported. Furthermore, a method of adding activated carbon or bentonite to caffeine (hydrate) (Non-Patent Document 1), and a method of mixing white alundum or light anhydrous silicic acid (Aerosil 200) with anhydrous caffeine (Non-Patent Document 2). ) Has been reported. Furthermore, a method of blending a sublimable drug and polyvinylpyrrolidone (Patent Document 10) has been reported.

  On the other hand, cysteines and the like have a problem of generating an unpleasant odor. As a method for preventing the smell of chemicals that generate odors such as cysteines, a sugar coating containing 5% to 60% of the weight of the uncoated tablet using a sugar coating liquid containing a sugar, an excipient and a binder ( Patent Document 11) and a method for reducing unpleasant odor formed by dry blending of L-cysteine (Patent Document 12) have been reported.

  However, any of these methods has a problem that the effect is insufficient or the manufacturing process becomes complicated.
