A medication used to relax the airways in the lungs to increase air flow is:
Bronchodilator
Doxycycline
Ace inhibitor
Anti-androgen therapy
The Correct Answer is A
A. Bronchodilators are medications specifically designed to relax the muscles around the airways, making it easier to breathe by increasing airflow. They are commonly used in conditions like asthma and chronic obstructive pulmonary disease (COPD).
B. Doxycycline is an antibiotic used to treat bacterial infections. It has no direct effect on airway muscles or airflow.
C. ACE inhibitors are used primarily to treat high blood pressure and heart failure. They do not act on the airways and are not used to improve airflow.
D. Anti-androgen therapy is used to reduce levels of male hormones, typically in the treatment of prostate cancer or hormone-sensitive conditions. It has no role in bronchodilation or respiratory therapy.
