Mecysteine is used as a mucolytic in respiratory disorders associated with productive cough. Mecysteine is known as a mucolytic
agent, it breaks down mucus. It works by breaking some
of the chemical bonds between the molecules in mucus. It is given orally in a usual dose of 200 mg three times daily before meals reduced to 200 mg twice daily after 6 weeks. A rapid clinical effect can be achieved by giving 200 mg four times daily for the first 2 days. Mecysteine has also been given by inhalation.

The effects of L-cysteine methyl ester (Mecysteine) on behavior of mucus glycoproteins in canine tracheal secretory cells were investigated histologically and histochemically. Low concentrations (10(-7) and 10(-6)M) of L-cysteine methyl ester produced, as histological changes, decreases in the total goblet cell number and the thickness of the acini of submucosal glands, and an increase in the acinar inner diameter. On the other hand, L-cysteine methyl ester at 10(-5) and 10(-4)M produced an increase in the thickness of the acini and a slight decrease in the acinar inner diameter.
