Expectoration
"As a heathcare professional having given Mucomyst to patients over more than 30 year career, I&#039;ve yet to observe any benefit from the aerosolization of this med. I don&#039;t want to minimize the previous comments. Used during a bronchoscopy in liquid wash, it will dissolve thick mucus quickly and effectively but the benefit of aerosolization has not been demonstrated or established in any controlled study. Also, after more than 24 hours of use, the lung tissue will begin to &quot;weep,&quot; this is a very caustic substance to lung. Too often it&#039;s order for a specific problem area of the lung. As the laws of nature take effect in that gas follows the path of least resistance, Mucomyst is delivered to all areas of lung with minimal effect to the problem."
