Embodiment 1

[0043] This embodiment provides a pharmaceutical composition containing ketamine, the preparation method of which comprises the following steps:

[0044] formula:

[0045] Ketamine 16000mg Citric Acid Monohydrate 120mg Sodium edetate 5mg Cellulose 50mg Tween 80 2mg preservative 0.1mg

[0046] Wherein the cellulose is microcrystalline cellulose, and the preservative is potassium 2,4-hexadienoate.

[0047] Mix the above-mentioned ketamine, citric acid monohydrate, sodium edetate, cellulose, Tween 80, and preservatives, adjust the pH from 4.2 to 4.8 with 1N sodium hydroxide, and then add the injection Dilute to 100mL with water, and mix well to obtain the pharmaceutical composition. The pharmaceutical composition can be loaded into a spray device, and then the pharmaceutical composition is atomized and sprayed out by means of a manual pump or the like.

Abstract

The invention relates to a ketamine-containing pharmaceutical composition as well as a preparation method and application thereof. The ketamine-containing pharmaceutical composition comprises the following components in parts by weight of 16000 to 16500 parts of ketamine; 120 to 180 parts of citric acid; 5 to 15 parts of ethylene diamine tetraacetic acid salt; 40 to 100 parts of an adsorbent; 2 to 8 parts of Tween 80; 0.1-4 parts of a preservative; and the absorbent is a cellulose adsorbent. The ketamine-containing pharmaceutical composition disclosed by the invention can realize a very good drug effect through nasal administration.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a pharmaceutical composition containing ketamine and its preparation method and application. Background technique [0002] Depression is already an extremely common severe mental disorder. The main clinical manifestations are depressed mood, low self-esteem, pessimistic world-weariness, cognitive dysfunction and weakened willpower. Some patients are accompanied by self-injury, suicide and other behaviors.
