After insertion of the drops into the ear, the urea hydrogen peroxide complex liberates oxygen which acts to break up the hardened wax. The hydrogen peroxide component is also an antiseptic, especially in sites with relative anaerobiosis. The glycerol assists in softening the wax, so that it may more easily be removed from the ear, either with or without syringing. The urea acts as a mild keratolytic, helping to reduce the keratin-load in the wax debris, thereby assisting penetration of the other components.
Exterol is intended only for the treatment of impacted wax in the external auditory canal. The ingredients of the formulation are therefore readily available for intimate contact with the affected area, as the drops are instilled into the ear and retained therein for several minutes by tilting the head.
