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.
Types of Asthma Inhalers. There are two main types of inhalers for asthma: long-term and short-term. Long-term inhalers are for preventative long-term treatment of asthma. This would be a daily-use inhaler that prevents asthma from worsening and even makes it better steadily.
