So the long-acting bronchodilator is one of the new therapies that we've had available for the last couple of years which really has improved the quality of life of many of our patients, and is especially helpful in those patients who have nighttime wheezing, whose sleep is disturbed by coughing and wheezing. And you say, use the drug twice a day. The difficulty is to remember to use it when you're feeling great. If you're feeling great, it's real easy to forget. But I think the important thing is to use it, to use it very carefully and really, we're telling people to use drugs by inhalation.
Most people know how to swallow pills.
Pills are easy to swallow, but inhalation technique is something that is a bit more complicated, people really have to spend time thinking about how they're using an inhaler. And a couple of the key points is that the inhaler should be actuated at the same time a breath is started, it should be a slow, deep inhalation that lasts several seconds, and then about 7 to 10 seconds of breath-holding. Most people will use it through spacers and spacers really help for some of the inaccuracies of depressing the canister at the right moment. Oh, probably talking a couple of minutes at most. Certainly worth your time, I'd say.
