The invention relates to a lidocaine compound preparation, wherein the active component comprises lidocaine. In the compound preparation, an aloe extract and / or chitosan and a rosemary extract as the active components as well as inactive component auxiliary materials are added. Relative to 100 parts by weight of lidocaine, the content of the aloe extract does not exceed 5000 parts by weight, the content of chitosan does not exceed 5000 parts by weight and the content of the rosemary extract does not exceed 200 parts by weight. An aerosol using the lidocaine compound preparation is environment-friendly, stable in physical and chemical properties, good in dispersion and excellent in film-forming property, has the itch-reliving, inflammation-diminishing and sterilizing and self-healing functions, is less in irritation to skins and can be widely applied to infection caused by mild cut, bruise, burn, sunburn and soft tissue injury of skins, mosquito bite, pruritus and miliaria and is used to alleviate symptoms such as local muscular pain, arthralgia and wet.

AI Technical Summary

Problems solved by technology

[0007] Another object of the present invention is to solve the problem that the lidocaine preparations for external use used in the past for antipruritic, bactericidal and anti-inflammatory effects have many western medicine active ingredients, especially the aerosol products are very easy to form fine particles after spraying, the dispersion is uneven, and the product is not stable. It has problems such as film-forming or poor film-forming properties, and cannot promote skin self-repair; provide a lidocaine compound aerosol that can effectively overcome the above problems and has good film-forming properties
