This drug is just a mucolytic. Along the same lines as Mucinex and NAC. It helps break up mucus in the lungs so it is easier to cough out. My pulmonologist has me take Mucinex daily to break up the mucus and prevent mucus plugs. My last CT scan showed mucus plugs and my doctor really does not want to have to do another bronchoscope to remove them. Hence, the Mucinex. I seem to be hacking out a lot more mucus since I have been taking it daily. I just had another CT scan and see the doctor in 10 days. So I will see how well I did getting the mucus out. I also use my acapella and spirometer 5 times a day to help break up the mucus. Take care and God Bless!
