You may be using an inhaler for asthma, or other lung diseases. You wonder why your inhaler sometimes gives the relief you want, but sometimes it doesn't. In this workshop, see how your breathing can affect your medicine's delivery to your lungs. See an artificial lung at the School of Pharmacy - have your breathing capacity tested and see where and how much drugs go to your lungs when you take a puff from an inhaler. Thus, you will find why your inhaler sometimes does not work.
