Introduction
Carboxymethylcysteine is an active derivative obtained by carboxylmethylating cysteine. It has excellent hydrophilicity and excellent viscosity regulation ability. Unlike typical expectorant ingredients, it does not directly break down fibrin in phlegm, but instead affects the type and structure of mucin secreted by mucosal cells, making thick secretions easier to clear by the ciliary system. This mode of action gives it unique value in maintaining airway patency.
