When you use an allergy inhaler the medicine acts on which type of receptor?

Allergy inhalers, commonly used to treat asthma and other respiratory conditions, often contain medications called beta-agonists. Beta-agonists work by binding to and activating beta-adrenergic receptors, which are found in the smooth muscles of the airways.

When activated, these receptors cause the muscles to relax and widen, which helps to improve airflow and relieve symptoms such as wheezing, coughing, and shortness of breath.

Beta-adrenergic receptors belong to the family of G protein-coupled receptors (GPCRs), which are a large group of cell surface receptors that play crucial roles in various physiological processes.
