Inspite of all these medicines my wife is still having coughing and I think mainly because of sphutum stuck in lungs which is not getting expelled easily and she is struggling alot. I m a general physician, thinking of giving Asthalin inhaler spray. Kindly suggest if it's correct or advice a  better medication for easily expellation of sphutum/phlegm from lungs. She is having slight wheezing also near apical area and having exersion on breathing.
