Which medication is classified as a bronchodilator?

Codeine
Calan
Albuterol
Inderal

The correct answer is: Albuterol

The classification of albuterol as a bronchodilator is accurate because it is specifically designed to relax the muscles in the airways, leading to dilatation (widening) of the bronchi and bronchioles and making it easier to breathe. This medication is commonly prescribed for conditions such as asthma and chronic obstructive pulmonary disease (COPD), where airway constriction is a significant concern. In contrast, codeine is an opioid used primarily for pain relief and cough suppression but does not have any bronchodilator effects. Calan, which contains verapamil, is a calcium channel blocker often used to manage hypertension and certain types of heart rhythm disorders, not respiratory issues. Inderal, or propranolol, is a beta-blocker used mainly for managing blood pressure and anxiety, and it can actually constrict airways rather than dilate them in individuals with asthma or related conditions. Thus, the unique action of albuterol in promoting airway dilation establishes its classification as a bronchodilator.
