Which drug is classified as a bronchodilator?

Xopenex is classified as a bronchodilator because it is a medication specifically designed to relax and open the airways in the lungs, making it easier to breathe. It contains the active ingredient levalbuterol, which works by stimulating beta-2 adrenergic receptors in the smooth muscle of the airways. This action causes the muscles to relax, resulting in bronchodilation, which is essential for treating conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Other medications listed, such as Keflex, Geodon, and Diflucan, serve different purposes. Keflex is an antibiotic used to treat bacterial infections; Geodon is an antipsychotic used to manage schizophrenia and bipolar disorder; and Diflucan is an antifungal medication used to treat fungal infections. None of these medications have bronchodilator properties. Therefore, Xopenex stands out as the only drug in the group that functions to improve airflow in the respiratory system.
