Flegnil DS 250 mg Syrup

carbocisteine reduces the viscosity of non-infected secretions from mucous cells in the respiratory tract. The mucolytic action is due to two mechanisms. It breaks the disulphide bonds which cross-link certain glycoprotein molecules present in the mucus and it also alters local ionic charges, both of which factors affect the viscosity of mucus. There is also evidence that it alters the composition of mucin secreted by the respiratory mucosa, decreasing the proportion of neutral glycopeptides and increasing the sialoglycopeptides.
