Quick-disintegrating tablet in buccal cavity and manufacturing method thereof

The present invention relates to a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent, which is obtained by uniformly mixing the saccharide with a low melting point in the tablet so that a bridge will be formed between said drug and / or said diluent particles by the product of melting and then solidification of this saccharide with a low melting point. Moreover, the present invention relates to a method of manufacturing a quick-disintegrating tablet in the buccal cavity comprising a drug, a diluent and a saccharide with a relatively lower melting point than the drug and the diluent, which comprises (a) the process whereby tablet starting materials including a drug, a diluent, and a saccharide with a relatively lower melting point than the drug and the diluent are molded under the low pressure necessary for retaining the shape of a tablet, (b) the process whereby the molded product obtained in process (a) is heated to at least the temperature at which this saccharide with a low melting point will melt, and (c) the process whereby the molded product obtained in process (b) is cooled to at least the temperature at which the molten saccharide with a low melting point solidifies. The present invention presents a quick-disintegrating tablet in the buccal cavity that can be used for practical purposes in that it has almost the same properties as conventional oral pharmaceutical tablets, that is, it has sufficient tablet strength that it can be used with automatic unit dosing machines, and it is produced by conventional tableting machines, and a manufacturing method thereof. Moreover, the present invention presents a quick-disintegrating tablet in the buccal cavity which, in comparison to conventional quick-disintegrating tablets in the buccal cavity, has increased tablet strength and an improved friability without prolonging the disintegration time in the buccal cavity, and a manufacturing method thereof.

Method for preparing electrothermal film by graphene aqueous slurry

The invention discloses a method for preparing an electrothermal film by graphene aqueous slurry. The method comprises the steps of: (1) adding deionized water and an amine compound to solid acrylic resin to obtain water-soluble acrylic resin; (2) adding graphene and an auxiliary agent to the water-soluble acrylic resin, and dispersing and mixing the water-soluble acrylic resin to obtain a homogeneous dispersion liquid; (3) adding a binder to the homogeneous dispersion liquid, and stirring and mixing the homogeneous dispersion liquid to obtain the graphene aqueous slurry; and (4) coating a film-forming carrier with the graphene aqueous slurry to form a graphene conducting layer and drying the graphene conducting layer to obtain the electrothermal film. The electrothermal film with excellent thermal conductivity and electrical conductivity can be prepared with the aqueous slurry; no organic solvent is added in the preparation process; the problem of VOC emission does not exist; and the method is safe and environment-friendly. Compared with other technologies that require special modification of filler, the preparation method is simple; coupling treatment is not carried out on an exothermic material by adoption of a coupling agent; the existing production technology can be simplified; and the production cost is reduced.
