RT here.... I would like to know why you're giving all those medicines in the first place? Is the patient in exacerbation from COPD or Asthma? STOLIK19: WRONG....Inhaled corticosteroids DO NOT decrease mucus production. RIGHT....Brovana should not be mixed with other meds. JUSTBEACHYNURSE: NONE of those drugs interact with alveoli. They do alleviate BRONCHO-constriction. Bronchus and bronchioles. FIONA59: Brovana is NOT available in an inhaler. It is nebulizer only. All of what you are asking can be answered by your Respiratory Therapist. If you dont have them on staff then find one. Very valuable resource for pulmonary disorders and diseases and how they are treated. Why do I recommend this...Not because I'm an RT but because your querry depends on so many variables. What type of nebulizer? Age of the patient? The different conditions under the umbrella term "COPD"? Emphysema vs. Chronic Bronchitis. Medication side effects on this particular patient? With warmest regards.... Baldzilla55
