An aerosol and method of making and use thereof

By combining local anesthetic drugs with specific penetration enhancers, film-forming agents, and mixed propellants, the problems of low penetration efficiency, short duration of action, and unpleasant taste of existing aerosols in the treatment of premature ejaculation have been solved. This has resulted in aerosols that are fast-acting, long-lasting, uniformly covered, and environmentally friendly, thus improving treatment efficacy and patient compliance.

AI Technical Summary

Technical Problem

Existing local anesthetic aerosols for treating premature ejaculation suffer from problems such as low drug penetration efficiency, short duration of action, uneven coverage, easy phase separation, sedimentation, and unpleasant taste, making it difficult to achieve a comprehensive effect of rapid onset, long-lasting effect, system stability, and environmental friendliness.

Method used

An aerosol is formed by combining local anesthetic drugs with specific penetration enhancers, film-forming agents, and mixed propellants (hydrofluorocarbons and hydrofluoroolefins). The penetration enhancers improve the drug penetration rate, the film-forming agents enable precise control of drug release, the mixed propellants provide stable atomization power, and sensory modifiers are added to mask unpleasant tastes.

Benefits of technology

It achieves rapid onset of action, long-lasting effect, uniform coverage, high stability and environmental protection of aerosols, thereby improving the reliability of drug use and patient medication compliance.
