A Duo Ting
A Duo Ting Uses, Dosage, Side Effects, Food Interaction and all others data.
A Duo Ting is a prodrug that is metabolised into N-thiodiglycolyl-homocysteine whereby free thiol groups are formed leading to the opening of the disulphide bonds of the bronchial mucoproteins, thus reducing the viscosity of mucus and purulent sputum. It also antagonises the local formation of free radicals and inhibits elastase enzyme activity and bacterial adhesion to epithelial cells.

Uses
A Duo Ting is a mucolytic drug used in the treatment of acute and chronic respiratory diseases. It also improves the symptoms associated with short episodes of chronic bronchitis.
A Duo Ting is also used to associated treatment for these conditions: Excess mucus or phlegm, Airway secretion clearance therapy
How A Duo Ting works
A Duo Ting, is an orally administered mucolytic agent. It is classified as a thiol derivative and produced for the management of symptoms caused by chronic obstructive bronchitis. A Duo Ting contains sulfhydryl groups which are released after hepatic first-pass metabolism in the liver. Its active metabolites (3 in number) exert both mucolytic activity and scavenging activity against free radicals. A Duo Ting acts to regulate the production of mucus in the airway and regulates its viscosity while enhancing mucociliary transport. This leads to an increase in expectoration. A Duo Ting shows inhibition against the effects of free radicals from cigarette smoke. Clinical studies in patients with chronic obstructive lung disease (COPD) have shown that this drug is generally safe and well tolerated. A Duo Ting 300mg twice daily reduced cough (both frequency and severity) and sputum viscosity more quickly and more effectively than placebo and reduced the adhesivity of sputum more effectively than ambroxol 30mg twice daily. Co-administration of erdosteine and amoxicillin in patients with acute infective exacerbation of chronic bronchitis resulted in higher concentrations of the antibiotic in the sputum, leading to earlier and more pronounced amelioration of clinical symptoms compared with placebo. A Duo Ting is associated with a low incidence of adverse events, most of which are gastrointestinal and generally mild.
