Question

Quizplus · Accepted Answer

The medication that contains beta-2 sympathetic properties is the best choice for an asthmatic patient. Beta-2 receptors are found in the airway smooth muscle, and their activation leads to relaxation of the muscles, resulting in bronchodilation and improved airflow. Therefore, drugs such as albuterol, salbutamol, and terbutaline, which are beta-2 agonists, are commonly used in the treatment of asthma.
