What condition do bronchodilators primarily treat?

Bronchodilators primarily treat asthma and other pulmonary conditions by relaxing the muscles around the airways, making it easier for individuals to breathe. These medications work by dilating the bronchial passages, which can become constricted in conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory ailments. By increasing airflow to the lungs, bronchodilators help alleviate symptoms like wheezing, coughing, and shortness of breath, which are common in these conditions.

In contrast, the other options relate to different health issues and are treated with other classes of medications. Hypertension is primarily managed with antihypertensives, congestive heart failure often requires diuretics or ACE inhibitors, and osteoarthritis is typically treated with analgesics, anti-inflammatory medications, and physical therapy. Therefore, understanding that bronchodilators are specifically designed to target issues related to the airways highlights their role in managing asthma and pulmonary conditions effectively.
