Summary: Although twice-daily administration of ICS is often better to optimize asthma parameters, in many patients, asthma can be sufficiently controlled by a once-daily regimen of most ICS. An increased frequency of dosing seems preferable if asthma becomes uncontrolled or is severe, although this requires further study.

What is the mechanism of action of inhaled corticosteroids?
These effects of corticosteroids are produced through inhibiting the recruitment of inflammatory cells into the airway by suppressing the production of chemotactic mediators and adhesion molecules and by inhibiting the survival in the airways of inflammatory cells, such as eosinophils, T-lymphocytes and mast cells.
What are ICS drugs?

How effective are ICS in asthma?
There is no doubt that the early use of ICS has revolutionized the management of asthma, with marked reductions in asthma morbidity and improvement in health status. ICS are now recommended as first-line therapy for all patients with persistent asthma [38]. Several topically acting corticosteroids are now available for inhalation (Figure 8). ICS are very effective in controlling asthma symptoms in asthmatic patients of all ages and severity. ICS improve the quality of life of patients with asthma and allow many patients to lead normal lives, improve lung function, reduce the frequency of exacerbations and may prevent irreversible airway changes. They were first introduced to reduce the requirement for oral corticosteroids in patients with severe asthma and many studies have confirmed that the majority of patients can be weaned off oral corticosteroids [3]. By contract ICS are poorly effective in COPD [39].
How do corticosteroids help with asthma?
They suppress inflammation mainly by switching off multiple activated inflammatory genes through reversing histone acetylation viathe recruitment of histone deacetylase 2 (HDAC2) . Through suppression of airway inflammation ICS reduce airway hyperresponsiveness and control asthma symptoms. ICS are now first-line therapy for all patients with persistent asthma, controlling asthma symptoms and preventing exacerbations. Inhaled long-acting β2-agonists added to ICS further improve asthma control and are commonly given as combination inhalers, which improve compliance and control asthma at lower doses of corticosteroids. By contrast, ICS provide much less clinical benefit in COPD and the inflammation is resistant to the action of corticosteroids. This appears to be due to a reduction in HDAC2 activity and expression as a result of oxidative stress. ICS are added to bronchodilators in patients with severe COPD to reduce exacerbations. ICS, which are absorbed from the lungs into the systemic circulation, have negligible systemic side effects at the doses most patients require, although the high doses used in COPD has some systemic side effects and increases the risk of developing pneumonia.
What is the most effective control for asthma?
Introduction. Inhaled corticosteroids (ICS, also known as glucocorticosteroids, glucocorticoids, steroids) are by far the most effective controllers used in the treatment of asthma and the only drugs that can effectively suppress the characteristic inflammation in asthmatic airways, even in very low doses.
How do corticosteroids work?
The major action of corticosteroids is to switch off multiple activated inflammatory genes that encode for cytokines, chemokines, adhesion molecules inflammatory enzymes and receptors [1]. These genes are switched on in the airways by proinflammatory transcription factors, such as nuclear factor-κB (NF-κB) and activator protein-1, both of which are activated in asthmatic airways and switch on inflammatory genes by interacting with coactivator molecules, such as CREB-binding protein, that have intrinsic histone acetyltransferase activity. This results in acetylation of core histones, which opens up the chromatin structure so that gene transcription is facilitated [13]. In artificial over-expression systems activated GR may directly interact with NF-κB and AP-1 to inhibit their activity, but this does not appear to occur in asthmatic patients treated with inhaled corticosteroids [14]. Corticosteroid-activated GR also interact with coactivator molecules and this inhibits the interaction of NF-κB with coactivators, thus reducing histone acetylation [1,15]. Reduction of histone acetylation also occurs through the recruitment of histone deacetylase-2 (HDAC2) to the activated inflammatory gene complex by activated GR, thereby resulting in effective suppression of all activated inflammatory genes within the nucleus (Figure 4). This accounts for why corticosteroids are so effective in the control of asthmatic inflammation, but also why they are safe, since other activated genes are not affected.
Why are ICS added to bronchodilators?
ICS are added to bronchodilators in patients with severe COPD to reduce exacerbations.
How do corticosteroids regulate gene expression?
Corticosteroids may regulate gene expression in several ways. Glucocorticoids enter the cell to bind to glucocorticoid receptors in the cytoplasm that translocate to the nucleus. GR homodimers bind to glucocorticoid-response elements (GRE) in the promoter region of steroid-sensitive genes, which may encode anti-inflammatory proteins. Less commonly, GR homodimers interact with negative GREs to suppress genes, particularly those linked to side effects of corticosteroids. Nuclear GR also interact with coactivator molecules, such as CREB-binding protein (CBP), which is activated by proinflammatory transcription factors, such as nuclear factor-κB (NF-κB), thus switching off the inflammatory genes that are activated by these transcription factors. Other abbreviations:SLPI: secretory leukoprotease inhibitor; MKP-1: mitogen-activated kinase phosphatase-1; IκB-α: inhibitor of NF-κB; GILZ: glucocorticoid-induced leucine zipper protein; POMC: proopiomelanocortin; CRH: corticotrophin releasing factor.
What are some examples of genes that are activated by corticosteroids?
Examples of genes that are activated by corticosteroids include genes encoding β2-adrenergic receptors and the anti-inflammatory proteins secretory leukoprotease inhibitor and mitogen-activated protein kinase phosphatase-1 (MKP-1) which inhibits MAP kinase pathways.
What is ICS in asthma?
Purpose of review: Inhaled corticosteroids (ICS) are the mainstay of asthma therapy. Although compliance to this type of medication is often suboptimal and once-daily dosing can help to improve adherence to the treatment, the clinical implications of such a mode of administration should be determined.
Can asthma be treated with increased frequency?
An increased frequency of dosing seems preferable if asthma becomes uncontrolled or is severe, although this requires further study. A therapeutic trial should, however, be done to ensure that asthma control is adequate.

What is the most common cause of admission to the emergency department?
Asthma is a prevalent chronic disease of the respiratory system and acute asthma exacerbations are among the most common causes of presentation to the emergency department (ED) and admission to hospital particularly in children. Bronchial airways inflammation is the most prominent pathological feature of 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 exacerbations?
These exacerbations are usually triggered by allergens; including pollens, animal dander, dust mites, and mold; viral respiratory tract infections; irritants such as smoke and dust; cold air and exercise. 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 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. In response to infection they secret chemokines like interleukin-8 and CCL-5 that can attract inflammatory cells including neutrophils and lymphocytes that could exacerbate the already existing allergic inflammation.[7] This finding is supported by epidemiologic observations that allergen sensitization and respiratory viral infections can synergize to cause asthma exacerbation.[8] Children who are atopic are more likely to have virally induced wheezing and respiratory distress than nonatopic children.[9] Bacteria like Hemophilus influenze and Moraxella catarrhalis, have been recently shown to be associated with acute wheezing episodes in children.[10] Their role and the role of atypical bacteria as triggers of acute asthma are still controversial.[11]

When was cortisone first used for asthma?
The effect was remarkable and that work won the Nobel Prize the next year. It also started a series of trials of corticosteroids in various inflammatory conditions. The first use of corticosteroid to treat acute asthma exacerbation was in 1956. [35] 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. In 1972, Clark showed for the 1sttime that inhaled beclomethasone was effective in the management of asthma with less adverse effects than systemic steroids.[36] Numerous reports came afterwards describing the efficacy of oral prednisone and prednisolone , IV methylprednisolone and ICS such as triamcinolone, budesonide, and fluticasone in the management of asthma. These effects are mediated through various genomic and nongenomic mechanisms.[37] Table 2shows some common systemic corticosteroids and their relative potency.
