In short, corticosteroids lower the inflammation in the body and, specifically for asthmatics, in the lungs. Corticosteroids mimic the hormones that are produced naturally in the body (more specifically the adrenal glands). When the dose is more than what the body naturally makes, it suppresses inflammation.

Are inhaled corticosteroids effective in the treatment of bronchial inflammation?
Bronchial airways inflammation is the most prominent pathological feature of asthma. Inhaled corticosteroids (ICS), through their anti-inflammatory effects have been the mainstay of treatment of asthma for many years.
Is intravenous steroid concentration (ICS) effective in the treatment of acute asthma?
The use of ICS in the treatment of acute asthma was studied in four contexts: In comparison to placebo, In comparison to systemic corticosteroids, As add on therapy to systemic steroids with continuation after discharge from the ED, or As add on therapy to systemic steroids within the ED stay period only.
Why do you need an oral corticosteroid for asthma?
Oral corticosteroids (OCS) When our asthma is flaring up and our daily maintenance ICS aren’t enough to keep asthma symptoms at bay, your doctor may put you on an oral corticosteroid for a short period of time to decrease the amount of inflammation in the lungs.

Corticosteroids have become center stage in the treatment and prevention of asthma exacerbations. They come in three forms: oral, inhaled, and intravenous (IV).
What does "set" mean in asthma?
When providing education for asthmatics, in the respiratory field we use the SET mnemonic. SET stands for S welling, E xcess mucus, and T ightness. These are the three main things that happen during an asthma flare-up or asthma attack. Inflammation in the lungs is what causes the swelling which makes it difficult to breathe. Mucus production is increased and when combined with the swelling and tightness, causes wheezing. Tightness happens from both the swelling and bronchospasm. These three things create a perfect storm when you are exposed to a trigger.
Can asthma be controlled without breathing?
Not everyone will experience the same side effects and some might not experience any at all. You will have to weigh the options with your doctor and decide what is the best course of action for your specific asthma.

Which corticosteroids are more effective for asthma?
Development of corticosteroids that have less mineralocorticoid activity, like prednisone, and later those that have no mineralocorticoid activity, like dexamethasone, made corticosteroids more attractive therapies to use in asthma.
How long after asthma exacerbation can you take corticosteroids?
Systemic corticosteroids were found to speed resolution of symptoms, decrease the rate of admission and decrease the rate of relapse if administered for 3-5 days after the acute exacerbation. More detailed discussion about the use of systemic corticosteroids in the treatment of acute asthma can be found below.
What causes asthma in children?
The most common cause of acute asthma exacerbation in both adults and children, but more in children, is viral respiratory tract infections. Viruses may be responsible for up to 80% of wheezing episodes in children and 50-75% of episodes in adults.[5] . Many viruses can cause exacerbation of asthma symptoms, the most important ...
What is the most common pathological feature of asthma?
Bronchial airways inflammation is the most prominent pathological feature of asthma. Inhaled corticosteroids (ICS), through their anti-inflammatory effects have been the mainstay of treatment of asthma for many years. Systemic and ICS are also used in the treatment of acute asthma exacerbations. Several international asthma management guidelines ...
What are the most common viruses that cause asthma?
Many viruses can cause exacerbation of asthma symptoms, the most important and most common is rhinovirus. [6] . Respiratory syncycial virus and influenza virus also cause significant proportion of exacerbations. Airway epithelial cells play a major role in the pathology of virally induced asthma exacerbation.
What are the symptoms of asthma?
Examination of patients with acute asthma may reveal increased respiratory rate, retractions (accessory respiratory muscle use), wheezing, oxygen desaturation on pulse oximetry and in more severe cases, inability to speak, silent chest, with reduced respiratory lung volumes, cyanosis, and change in mental status.
Do asthma patients respond to corticosteroids?
Patients tend to have severe, more aggressive, and poorly controlled asthma. They usually do not respond to corticosteroids as well as the eos inophilic type. In the paucigranulocytic phenotype, bronchial neutrophils, and eosinophils are much lower.[4] Asthmatic patients frequently experience acute exacerbations.
