Fudosteine (Cleanal) is a mucolytic agent.^[1] 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.^[2]

Fudosteine works by increasing mucin secretion by inhibiting expression of the protein mucin 5AC.^[3]
