Mode of action: Ambroxol

Ambroxol is the active agent in Mucosolvan®. It makes phlegm in the airways thinner and less sticky. It does this by increasing the body's natural production of surfactant. This contributes to a secretomotoric effect: it helps the cilia - tiny hairs that line the respiratory tract - to transport the phlegm out of the lungs. Here is a step-by-step description of how Ambroxol works:

1. Ambroxol is quickly metabolised by the body. It goes straight to work at the mucus-secreting cells, where it changes the mucus so it becomes less viscous. This thinner, more liquid mucus helps lift the heavy, sticky phlegm off the walls of the airways.

2. Ambroxol frees and activates the cilia. Thanks to the effect of the thinner mucus, the cilia are no longer clogged by the thick, sticky phlegm. They are free to move again and help to push the phlegm up and out of the respiratory tract. Furthermore, Ambroxol enhances the movement of the cilia so they transport phlegm out of the airways more quickly.

3. Ambroxol is not a cough suppressant. It does not interfere with the body's natural cough response. This is important, because coughing is still needed to eject the excess phlegm from the airways. Ambroxol makes it easier to get the phlegm moving again.

4. As the active ingredient in Mucosolvan®, Ambroxol has offered proven safety and effectiveness for many years.
