ACETYLCYSTEINE
Background and Date of Approval
The U.S. FDA approved Acetylcysteine to treat paracetamol overdose and respiratory conditions on January 23, 2004. Acetylcysteine is an antidote containing the active ingredient Acetylcysteine. It belongs to the mucolytics agent class of medications. Acetylcysteine thins and loosens thick phlegm, making it easier to cough up and clear from the respiratory system.
Uses
Acetylcysteine tablet is used to treat airway diseases such as bronchitis (inflammation of the bronchial tubes), emphysema (destruction and enlargement of the air sacs), mucoviscidosis (affecting the lungs and digestive system), and bronchiectasis (permanent widening and inflammation of the bronchial tubes).
