Asthalin inhaler is a pharmacological agent that functions as a bronchodilator, specifically formulated to alleviate symptoms in patients afflicted with respiratory disorders, most notably asthma and chronic obstructive pulmonary disease (COPD). The inhaler in question is composed of albuterol, which is also referred to as salbutamol. This particular drug falls within the category of short-acting beta-agonists.

The principal objective of the Asthalin inhaler is to mitigate the manifestations of bronchoconstriction, encompassing the constriction of airways, audible wheezing, respiratory distress, and thoracic constriction. This is accomplished by specifically targeting the smooth muscles present in the airways, resulting in their relaxation and consequent facilitation of enhanced airflow. The expeditious response of this inhaler designates it as a "rescue" or "reliever" inhaler, offering prompt alleviation during episodes of asthma or exacerbation of symptoms.
