Advair is not just an antiinflammatory drug but also a long acting bronchiodilator (anti-inflammatory drugs are completely different than bronchiodilators). It is actually a very good drug to take because of this. Unlike duoneb, or albuterol, the advair lasts quite a while. The duoneb and albuterol are short acting bronchiodilatos. The combinations of these two effects really in some aspects makes it one of the better drugs out there (in my opinion) as it does a lot to keep your airways open.
