A traditional Chinese medicine compound nasal spray with both immediate and sustained-release effects, its preparation method and application.

This invention relates to the field of traditional Chinese medicine compound preparations, specifically to a traditional Chinese medicine compound nasal spray with both rapid-release and sustained-release effects, its preparation method, and its application. The preparation method of the traditional Chinese medicine compound nasal spray with both rapid-release and sustained-release effects includes the following steps: Step S1: Preparing the traditional Chinese medicine compound composition into a microemulsion solution; the traditional Chinese medicine compound composition contains volatile oils; Step S2: Making the microemulsion solution to volume with distilled water, then adjusting the osmotic pressure with sodium chloride solution, and adjusting the pH with hydrochloric acid solution. This invention combines rapid and long-lasting effects. One-fifth of the traditional Chinese medicine compound composition in the nasal spray has a rapid-release effect, and its rapid-release mechanism can produce a protective effect the moment the virus invades the nasal cavity; while the four-fifths of the drug sustained-release microspheres in the spray have a long-lasting mechanism, which can prolong the drug's action time, fully adapting to the "time-limited characteristic" of influenza virus transmission up to 48 hours, filling the gap in current similar nasal sprays that lack sustained-release effects.
