Which medication is commonly used to treat Exercise-Induced Bronchospasm (EIB)?

Albuterol is a commonly used medication for treating Exercise-Induced Bronchospasm (EIB) due to its role as a bronchodilator. It works by relaxing the muscles in the airways, which leads to widening and opening the air passages to the lungs, allowing for improved airflow. This action is particularly beneficial for individuals who experience bronchospasm triggered by physical activity, as it helps relieve symptoms such as wheezing, shortness of breath, and chest tightness.

Albuterol is often administered through an inhaler, making it easily accessible for individuals to use preemptively before engaging in exercise or for prompt relief during an episode. Its rapid onset of action makes it a first-line treatment for managing acute symptoms associated with EIB, providing effective relief for patients.

Other medications listed in the options do not serve the same purpose in treating EIB. For instance, heparin and coumarin are anticoagulants used for preventing blood clots, and epinephrine, while a bronchodilator, is typically used for severe allergic reactions or anaphylaxis rather than as a standard treatment for EIB. Therefore, albuterol's specific mechanism of action and availability align closely with the needs of individuals experiencing symptoms of EIB, establishing
