Why Is Adrenaline Used in the Treatment of an Asthma Attack?

Adrenaline, which is also called epinephrine, is sometimes used to treat an asthma attack. The most recent guidelines, however, by the National Heart, Lung, and Blood Institute state that adrenaline should not be used for routine asthma exacerbation unless preferred drugs are not available.

Adrenaline

• Adrenaline works by reducing bronchospasms, which are constrictions of the muscles surrounding the airways. Reducing bronchospasms helps airways open, allowing better airflow. Adrenaline is most commonly delivered as an injection, but it is also available as an inhaled medicine.

Side Effects

• Adrenaline is non-specific, which means that it impacts systems other than the one being treated. Adrenaline can cause cardiac stimulation and tremors, in addition to reducing bronchospasms.

Quick Acting

• Adrenaline is very quick acting, making it ideal for emergency situations such as when there is also severe anaphylaxis.

Over-the-Counter

• Most asthma medication requires a prescription from your doctor. You can, however, find over-the-counter adrenaline (epinephrine) inhalers.

Emergency Availability

• Adrenaline is commonly available in emergency departments and ambulances, while there are cases where slow-acting beta agonists or delivery devices (such as spacers for children) are not available.
