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.
An inhaler is a device holding a medicine that you take by breathing in (inhaling). Inhalers are often used to treat chronic obstructive pulmonary disease (COPD). There are many different types of inhaler, which can be confusing.teroid inhalers are only used in combination with a long-acting beta-agonist inhaler (this can be with two separate inhalers or with a single inhaler containing two medicines).The main inhaled steroid medications are: 1  Beclometasone. 2  Budesonide. 3  Ciclesonide. 4  Fluticasone. 5  Mometasone.
