Methods of using the pharmaceutical compositions for treating patients with Alzheimer's disease for symptoms of depression, anxiety, agitation, delusions, hallucination, irritability and sleeping disorder, are also disclosed.

The present invention is directed towards the preparation of extended release Alprazolam formulation. The formulation thus obtained provides an efficient mode of delivery of Alprazolam in a continuous manner.

The invention relates to a preparation method of benzodiazothioketone serving as an intermediate of alprazolam. The preparation method comprises the following steps: performing a typical acylation reaction, a cyclization reaction and a vulcanization reaction on 2-amino-5-chloro-benzophenone (M2) serving as a raw material to obtain a benzodiazothioketone crude product (the HPLC (High Performance Liquid Chromatography) content is about 94 percent); and recrystallizing the crude product in a mixed solvent at the normal temperature to obtain a fine product of which the HPLC content is over 98.5 percent, wherein the melting point of the fine product is 238-242 DEG C (the melting range is below 3 DEG C). The preparation method has the advantages of small number of synthesis steps, mild process condition, easiness in controlling a refining method, high yield, high fine product content, controllable low production cost, reduction in environmental pollution, and contribution to industrialization.

The invention relates to a 1, 4-nitrosation-N-nitrosamine intermediate (I) compound in the synthesis of alprazolam, a preparation method and application thereof to the preparation of alprazolam. 7-chloro-5-phenylbenzodiazepinone is taken as an initial raw material, and the alprazolam is obtained by the synthesis through certain processes such as condensation ring-closure after a methylamination reaction and an N-nitrosation reaction. Other benzodiazepine derivatives can be synthesized through a 1, 4-nitrosation-N-nitrosamine intermediate obtained by the synthesis. The method has the advantages of unique process, steady product quality, mild process conditions, easy control, and high yield, and can control lower production cost and reduce environmental pollution.

The invention provides an alprazolam composition lyophilized tablet and a preparation method thereof, and relates to the technical field of medicines and medicine production. The tablet is prepared from alprazolam, starch and cane sugar, wherein starch and cane sugar are used as auxiliaries, common corn starch is subjected to heating treatment to improve the adhering and disintegrating effects of the starch in the tablet, so that the moldability of the tablet can be improved. The alprazolam composition lyophilized tablet only needs two auxiliaries of starch and cane sugar. According to the preparation method, a twice-cooling twice-heating lyophilizing process is adopted for the alprazolam composition lyophilized tablet, the moldability of the tablet can be better by means of twice cooling and twice heating, the solubility of the tablet can be improved, and the bioavailability of the tablet can be improved; the tablet is capable of overcoming the defect of conventional alprazolam tablets and reducing the types and usage of auxiliaries in the alprazolam tablets, is high in solubility and high in bioavailability, and can be used for guaranteeing the curative effect and safety of clinical administration.

The present invention describes the use of pharmaceutical compounds in pharmaceutical compositions for sublingual administration, including as active ingredient thereof, an agonist of the central receptor of benzodiazepinics chosen among diazepam, lorazepam, bromazepam, triazolam, alprazolam, flunitrazepam, nitrazepam and midazolam maleate, in a mixture with a pharmaceutical excipient consisting of, at least, 70% of the weight of the final formulation containing 40-45% by weight of lactose, 15-27% by weight of sorbitol and 12-16% by weight of cellulose.
