SMART Asthma Therapy
Asthma is a chronic inflammatory disease of the airways that causes frequent symptoms of coughing, chest tightness, wheezing and/or shortness of breath.
If the symptoms are less frequent than twice a week during the daytime and less than twice a month during the nights, it is termed “intermittent” asthma. If the symptoms are more frequent than twice a week during the daytime and more than twice a month during the nights, it is called “persistent” asthma. Persistent asthma is further subdivided into mild, moderate, and severe based on the severity and frequency of the asthma symptoms as well as lung function measurements obtained by pulmonary function tests.
Intermittent asthma is traditionally treated with an as needed “rescue” inhaler medication, which is usually an albuterol (e.g., ProAir, Proventil, Ventolin) inhaler. Albuterol is a short-acting beta 2 agonist bronchodilator medication which acts as a dilator of the bronchial tubes of the lungs. It provides quick relief for the wheezing, chest tightness, coughing, and shortness of breath that plagues asthma sufferers. The usual dose is 2 puffs from the inhaler every 4 to 6 hours as needed for symptom relief. Albuterol can also be used prior to exertion for the prevention of exercise-induced asthma symptoms.
Persistent asthma, on the other hand, needs a daily scheduled maintenance medication in order to control the inflammation that occurs in asthmatics. The daily maintenance medication helps prevent symptoms and preserve the lung function in the long term. The maintenance medication usually consists of a corticosteroid in the form of an inhaler [Flovent (fluticasone), QVAR Redihaler (beclomethasone), Asmanex (mometasone), Pulmicort (budesonide), Arnuity (fluticasone), Alvesco (ciclesonide), Aerobid (flunisolide)] which is usually taken either once or twice a day. There is also another maintenance therapy that does not include a corticosteroid. Such non-steroid maintenance medications typically are known as leukotriene antagonists [e.g., Singulair (montelukast), Accolate (zafirlukast), Zyflo (zileuton)]. It is up to the allergist and patient to decide which type of maintenance therapy is best for that patient.
Since a maintenance medication is needed in most persistent asthmatic patients, usually 2 different types of inhalers are needed in total – one for the daily preventive maintenance and the other for the as needed quick relief for asthma symptoms. Though it is an effective way of treating asthma, it can sometimes lead to confusion for some patients, so it is necessary for the board certified allergist to explain how and when to use both types of medications.
There has been a recent update in the recommendations for asthma management from the National Asthma Education and Prevention Program. The newer guidelines recommend one inhaler both for prevention and rescue therapy. This new recommendation is termed Single Maintenance And Reliever Therapy (SMART).
The recommended inhaler contains a combination of a corticosteroid (anti-inflammatory agent) and a short-acting beta 2 agonist bronchodilator to open the airways quickly. In addition to using it once or twice a day on a regular daily basis for maintenance, the patient can take one or two puffs from the same inhaler as needed for the rapid relief of the symptoms. SMART therapy is approved for children who are 5 years old and above.
Clinical studies have shown that SMART therapy reduces acute flare-ups, emergency healthcare visits, and hospitalizations compared to the traditional therapy in patients with moderate and severe persistent asthma. However, If the patient’s current therapy is controlling their asthma well and they are not having side effects, there is no need to make a change.
There are 2 main corticosteroid medications recommended for SMART therapy: budesonide and mometasone. These 2 corticosteroids can be used as the preventive component. Formoterol is a faster acting long-acting beta 2 agonist that is used as the rescue component. Only formoterol-containing formulations should be used. Formoterol has a more rapid onset bronchodilator effect than other long-acting beta 2 agonists, similar to albuterol. Budesonide/formoterol (i.e., Symbicort) is the most commonly used formulation for SMART therapy, but mometasone/formoterol (i.e., Dulera) may also be used.
