Ambroxol is used in the treatment of allergic disorders and the symptoms it can cause
How it Works
Ambroxol is used known as an antihistamine, it works by blocking histamine receptors and increasing the breakdown of mucus.Ambroxol works by selectively inhibiting the H1 histamine receptors therefore preventing histamine from acting on its receptors Ambroxol helps to alleviate the symptoms caused by hay fever or other allergies (such as a runny nose and watery eyes). Ambroxol has secretolytic properties, and it works by reducing the viscosity (thickness) of mucus, allowing for more of it to be removed from the body.
