Embodiment 1

[0038] Prescription composition:

[0039]

[0040]

[0041] The eszopiclone inclusion complex is prepared by spray drying with eszopiclone and β-cyclodextrin in a molar ratio of 1:1.

[0042] Preparation Process:

[0043] (1) Accurately weigh 29.2 g of β-cyclodextrin and 10.0 g of eszopiclone with a molar ratio of 1:1, respectively, heat the β-cyclodextrin with water to 50°C and dissolve it into a saturated solution. The clone was dissolved in 150 ml of acetone and slowly added to the above saturated solution of β-cyclodextrin, stirred in a constant temperature water bath at 65°C for 4-6 hours, and then the solution was spray-dried in a spray dryer to obtain eszopiclone inclusion complex powder;

Abstract

The invention belongs to the field of a pharmaceutical preparation, and in particular relates to a dexzopiclone oral fast-dissolving film and a preparation method thereof. The film mainly consists of such ingredients as a dexzopiclone inclusion compound, a film-forming material, a filling agent, a plasticizer, a flavoring agent and an antioxidant. The preparation method comprises the following processes: (1) preparing the dexzopiclone inclusion compound; (2) preparing a blank glue solution; (3) preparing a dexzopiclone drug-containing glue solution; and (4) coating and drying the drug-containing glue solution. The oral fast-dissolving film is capable of masking the bitterness of the dexzopiclone, and the film is unnecessary to be taken with water and is suitable for children, old people and insomnia patients having difficulty in swallowing; and moreover, the oral fast-dissolving film is good in flexibility and not easy to become broken, and the film is capable of fast dissolving in an oral cavity and is high in bioavailability.

Description
