A particulate substance mixture, preferably for use in the prophylaxis and/or treatment of a respiratory disorder includes a mucolytic substance and amorphous silicon dioxide. The mixture may also have the following characteristics: the amorphous silicon dioxide is hydrophilic silicon dioxide, the amorphous silicon dioxide has a mean particle diameter ≤20 μm, and an amount of the amorphous silicon dioxide is 0.1% by weight to 10% by weight, based on the total weight of the particulate substance mixture. |
