About Sprays and Aerosols

Aerosol means that the drug is co-packaged with a suitable propellant in a pressure-resistant sealed container with a specific valve device. In use, the contents are mainly ejected by the pressure of the ejector.


The spray is a preparation which is sprayed in the form of a mist by means of the pressure of a hand pump, and is also called a pneumatic agent, and does not contain a propellant. Since the sprayed droplets are relatively large, they are generally applied mainly to local applications, and the following sprays are mainly introduced as nasal sprays.
