Prescribed inhalers are beneficial for patients with obstructive pulmonary disease because they:

Inhalers prescribed for patients with obstructive pulmonary diseases, such as asthma or chronic obstructive pulmonary disease (COPD), primarily contain bronchodilators that work by activating Beta 2 receptors in the bronchial smooth muscle. This activation leads to relaxation and dilation of the airways, making it easier for patients to breathe. By opening the airways, these medications alleviate symptoms such as wheezing and shortness of breath, which are common in obstructive pulmonary diseases.

While some inhalers may also address inflammation or have effects on mucus production, the immediate and primary benefit of using inhalers in these patients is their ability to rapidly dilate the bronchi, improving airflow and reducing respiratory distress. This is particularly important during acute exacerbations when airway obstruction is often at its worst.
