Educational Pearls:
What is a Rescue Inhaler?
A rescue inhaler is a medication for people with asthma to quickly reverse the symptoms of an asthma attack.
Historically albuterol (Short Acting Beta Agonist (SABA)) monotherapy has been the mainstay rescue inhaler. This is because albuterol works fast and is relatively cheap. \n\n
What are Combination Rescue Inhalers?
Combination rescue inhalers contain a fast-acting bronchodilator as well as an inhaled corticosteroid (ICS)
The steroid helps to reduce some of the chronic airway inflammation that is worsening the asthma attack and can help to prevent future attacks
Examples include budesonide-formoterol and albuterol-budesonide
Global Initiative for Asthma (GINA), states that combination therapy is now the preferred reliever for adults and adolescents with mild asthma
What are the drawbacks of Combination Rescue Inhalers?
These inhalers are generally more expensive than just using a SABA inhaler which can be a barrier for some people \n\n
Improper use can also lead to conditions like thrush due to the addition of the steroid
