Fudosteine

Fudosteine (Cleanal) is a mucolytic agent. In Japan, it is approved for the treatment of bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, pulmonary tuberculosis, pneumoconiosis, atypical mycobacterial disease, and diffuse panbronchiolitis.

Fudosteine works by increasing mucin secretion by inhibiting expression of the protein mucin 5AC.
