Example Embodiment

[0024] The preparation method of the above-mentioned medicinal gel for treating insomnia is specifically implemented according to the following steps:

[0025] Step 1. Weigh separately according to mass percentages: Jujube saponins extract 2%~6%, poloxamer P40716%~22%, poloxamer P1881%~6%, PEG4006%~12%, paraben 0.01%~0.03%, the rest is phosphate buffer, the sum of the above mass percentages is 100%;

[0026] Step 2. Take part of the phosphate buffer solution, add the jujube saponins extract, dissolve it and place it in an ice water bath, slowly add poloxamer P407, poloxamer P188, PEG400 and paraben under magnetic stirring, and add the rest The phosphate buffer solution is evenly moistened and placed in a refrigerator at 4-10°C for 12-48 hours to fully swell and disperse the gel until a clear solution is obtained.

Abstract

The invention discloses a medicament for treating insomnia and a preparation method and application thereof. The medicament for treating insomnia is composed of the following components in mass percent: 2-6% of jujuboside extract, 16-22% of poloxamer P407, 1-6% of poloxamer P188, 6-12% of PEG400, 0.01-0.03% of nipagin and balance of phosphate buffer solution, wherein the sum of the mass percents is 100%. The medicament for treating insomnia disclosed by the invention adopts a temperature-sensitive gel as a dosage form of jujuboside, thus after the medicament is dripped in liquid form into the nasal cavity, the medicament can flow onto mucous membrane in the deeper olfactory region where the brain bioavailability is verified high for administration; the medicament changes into semi-solid with a biological adhesion action in the nasal cavity, thereby continuously attaching to the mucous membrane in the olfactory region, solving the problem that the traditional dosage form is liable to lose and result in lower bioavailability and transient administration, and improving the sleeping quality of patients continuously.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a medicine for treating insomnia, and also relates to a preparation method and application of the medicine gel.
