Problems solved by technology

Compound (R) shown in formula (I) has been reported in Chinese patent CN103202815B 1 and R 2 Both are freeze-dried preparations of salts of methyl), the preparation cycle of the freeze-drying process is long, about 5 days a production cycle, the amount of excipients is large, the cost of industrial production is high, and the preparation requires professional medical personnel to inject it, which is very inconvenient
[0004] Most of the current literature reports are that the compound shown in formula (I) is prepared as a freeze-dried powder preparation and then used clinically. The preparation process of this dosage form has a long production cycle and high production costs; clinically, it needs to be temporarily formulated into a solution before it can be used clinically. It is used under the guidance of a professional doctor, and it is often accompanied by injection pain during injection, which makes it inconvenient for patients to take medication and has poor compliance

Abstract

The invention discloses a benzodiazepine compound topical pharmaceutical composition, which comprises a benzodiazepine compound represented by formula (I) or a pharmaceutically acceptable salt thereof, a polymer dispersion carrier material, a thermal melt protector and optionally The fluxing agent, R in formula (I) 1 and R 2 See the description for the definition of , the topical pharmaceutical composition is for skin external use and transdermal administration; the preparation method of the topical composition includes the benzodiazepine compound, polymer dispersion The agent is micronized, a melting agent is optionally added, and mixed uniformly to obtain a physical mixture, which is then hot-melt extruded and micronized to obtain the benzodiazepine compound particles. Uses of the above pharmaceutical composition are also provided. The pharmaceutical composition can be used for calming the mind, sedation, hypnosis, improving sleep quality, clearing the mind after use, the compound represented by the formula (I) has no residue or accumulation in the body, does not affect the work of the next day, and is full of energy.

Description

technical field [0001] The present invention relates to pharmaceutical preparation technology, more particularly to a kind of benzodiazepine The topical pharmaceutical composition of the compound (namely the compound represented by formula (I)) and the preparation method and use thereof. The pharmaceutical composition can be used for calming the heart, soothing the mind, sedation, hypnosis, and improving sleep quality. Background technique [0002] The compound represented by formula (I) (wherein, R 1 Selected from hydrogen, methyl, ethyl, isopropyl; R 2 For methyl, ethyl) is a new type of benzodiazepine class of compounds, are short-acting sedatives. Clinically, it can be used for procedural sedation, induction and maintenance of general anesthesia, sedation of ICU patients, etc. Short-acting sedatives allow patients to regain consciousness quickly and be discharged from the hospital as soon as possible. In the face of the gradual increase in short-term hospitalizat...
