Abstract

The invention relates to the technical field of medicines, and provides a suvorexant tablet and a preparation method thereof, and the suvorexant tablet comprises 35-55 parts by weight of a suvorexant solid dispersion, 10-20 parts by weight of lactose, 30-50 parts by weight of microcrystalline cellulose, 11-20 parts by weight of a disintegrating agent and 0.5-3 parts by weight of a lubricant. According to the suvorexant tablet provided by the invention, the suvorexant is subjected to micro-powder treatment, the suvorexant and the copovidone are firstly prepared into the solid dispersion by adopting a hot melting process, and then the solid dispersion and various auxiliary materials are prepared into the tablet, so that the dissolution property of the indissolvable medicine suvorexant is improved, the absorption rate of the suvorexant in a human body is favorably improved, and the curative effect of the suvorexant is improved. Therefore, the bioavailability is improved.
