How does the asthmatic inhaler work?

During an asthma attack, the patient suffers a narrowing of the bronchioles – the final branches of the bronchi – followed by the contraction of the pectoral muscles and the inflammation of the mucosa, which leads to irregular and especially painful breathing.

What inhalers do is introduce bronchodilator substances into the lungs of the asthmatic. These drugs act on the nerve that governs the muscular activity of the bronchioles, relaxing the muscles , ventilating the airways and restoring the normal respiratory rhythm.

The use of inhaled, smoked or vaporized substances to treat asthma has been constant since ancient times, but it was in the 1950s, with the manufacture of pressurized inhalers, that this treatment became widespread.

The advantage of inhalers over other anti-asthmatic systems (injectable corticosteroids, pills) is that the drugs go directly to the place where they should produce their curative effect, that is, to the bronchial tubes, and act more quickly and effectively.
