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.
The standard metered-dose inhaler includes the blue inhaler (e.g. Ventolin) and has been used for several decades. It consists of a small can fitted into a plastic body with a mouthpiece. Each time you press the canister into the boot, one dose of drug is released.You need to press and inhale the medication.lue inhalers are great short-acting treatments: they can relieve the symptoms of an asthma attack within minutes. They are also commonly used as a long-term treatment, following a specific prescription; e.g. 2-3 doses a day for a certain period of time (at least several months).
