An aerosol precursor containing Chuanbei Xueli Plaster medicinal active ingredients and a method for dispersing it into nano-scale droplets

Abstract

The invention relates to an aerosol precursor containing medical components of Chuanbei Xueli Extract. The aerosol precursor comprises glycerine, propanediol, 1,3-butanediol, an aromatic substance and Chuanbei Xueli Extract of which the mass ratio is as follows: glycerine: propanediol: 1,3-butanediol: aromatic substance: Chuanbei Xueli Extract= (40-45): (20-25): (0-10): (0-10): (1-10). The invention also relates to a method for dispersing medical components in Chuanbei Xueli Extract into nanoscale fog drops, as well as an aerosol containing nanoscale fog drops. As the aerosol precursor contains medical components of Chuanbei Xueli Extract, when the aerosol precursor is placed in an electronic cigarette smoking set including an electric heating device to be heated, nanoscale fog drops can be obtained to bring more convenience for the medical components to be absorbed by a human body.

Description

technical field [0001] The invention relates to an aerosol precursor, in particular to an aerosol precursor containing medicinal components of Chuanbei Xueli Plaster and a method for dispersing it into nano-scale droplets. Background technique [0002] The main ingredients of Chuanbei Xueli Cream are Liqing Cream, Chuan Fritillaria, Ophiopogon japonicus, Lily, and Coltsfoot. The supplementary material is sucrose, which is brownish-yellow thick and semi-fluid, sweet in taste, and has the effects of moistening the lungs and relieving cough, promoting body fluid and relieving throat. Usually, the administration method of Chuanbei Xueli Cream is oral administration. On the one hand, the drug effect is slow; on the one hand, it will cause the irritation of the drug to the stomach; Drug utilization decreased. [0003] Aerosols generally refer to preparations that produce droplets when heated or pressurized. In the field of medicine and pharmacy, aerosols refer to preparations t...

Problems solved by technology

[0005] The representative patent for pressurized atomization of traditional Chinese medicine compound preparations is CN102949573A, in which an 80-100bar propellant such as trichlorofluoromethane, dichlorodifluoromethane or dichlorotetrafluoroethane is used to atomize the liquid medicine to To obtain micron-sized mist droplets, the above-mentioned injection pressure is too high, the airtightness of the propellant container tank is strict, the production cost is high, and the propellant itself is also expensive

In addition, with the increase of the amount of medicine used, the pressure inside the tank decreases continuously, and the drug atomization effect gradually becomes worse; moreover, such tanks can only be used once for consumers, increasing usage cost
