Introduction [edit]. A carboxyl group consists of a carbon double-bonded to an oxygen and also bonded to a-OH group. Compounds with carboxyl groups are called carboxylic acids or organic acids. The carboxyl group can act as an acid when by donating a proton (H +) to a solution and becoming ionized.
It therefore makes perfect sense to use the bronchodilator first, wait a few minutes, and then to use the steroid inhaler, after the airways have been opened up and are more relaxed. This way, the steroid can penetrate the lungs more effectively, and get down to decrease inflammation in your smaller airways.
To use the inhaler: 1  This medicine comes in a foil tray. Peel back the lid to open the tray. 2  Slide the inhaler cover down until you hear a clicking sound. The inhaler is now ready to use. 3  Turn your head away from the inhaler, and breathe out fully. Do not breathe into the inhaler.
