The most common adverse events are infections in the sinuses, airways, or mouth. Also, inhaled steroids may raise the overall risk of infection. Anyone using this type of medication should avoid exposure to chickenpox and measles. If exposed, they should seek medical advice immediately. Although it is uncommon, people with COPD who use inhaled steroids have a higher risk of pneumonia. It is important to consider this risk in proportion to the risk of COPD symptoms.
An inhaled steroid may reduce bone density, putting a person at risk of fractures and osteoporosis. Healthcare providers should screen adults for risk factors, run regular bone density tests, and request routine follow-ups. People using inhaled steroids should also have regular eye exams to identify possible adverse effects, such as cataracts , glaucoma , and blurred vision. To reduce the likelihood of adverse effects, healthcare providers should screen for possible drug interactions.
Rarely, inhaled steroids can cause hives , swelling, and a rash that requires immediate medical attention. Inhaled steroids are a crucial treatment for asthma and COPD. They deliver targeted doses of drugs to the airways and ensure that only small amounts reach the rest of the body. This can help control the symptoms of asthma or COPD while causing few adverse effects. Given the variety of inhaled steroids available, doctors and people receiving treatment should work together to decide upon the right medication and device.
Each situation will be unique. Healthcare professionals should provide continued coaching and assessments to improve inhaled steroid effectiveness and minimize the risk of adverse effects. Bronchodilators are drugs that open the airways, relieving the symptoms of respiratory conditions, such as asthma and emphysema.

Inhaled corticosteroids for asthma. Information about this medicine What are the most important things you need to know about your medicines? Why are inhaled corticosteroids for asthma used? Inhaled corticosteroids are used to help: You breathe better. Prevent and improve your asthma symptoms. Reduce asthma attacks. What are the two types of asthma medicines? Asthma medicines are divided into two groups. Long-term controller medicines are used every day. They can result in fewer asthma symptoms and can help prevent asthma attacks.
Quick-relief medicines help you breathe better during an asthma attack. You use them only when you need to. Most medicines for asthma are inhaled. These types of medicines go straight to the airways. What are some examples of inhaled corticosteroids for asthma?
How do inhaled corticosteroids for asthma work? What about side effects? General information about side effects All medicines can cause side effects.
But sometimes side effects can be a problem or can be serious. The relationship between knemometry measurements and final height are uncertain since low doses of oral corticosteroid that have no effect on final height cause profound suppression. Metabolic Effects. Several metabolic effects have been reported after ICS, but there is no evidence that these are clinically relevant at therapeutic doses.
In normal individuals high dose inhaled BDP may slightly increase resistance to insulin. However, in patients with poorly controlled asthma high doses of BDP and budesonide paradoxically decrease insulin resistance and improve glucose tolerance, suggesting that the disease itself may lead to abnormalities in carbohydrate metabolism. Psychiatric Effects.
There are various reports of psychiatric disturbance, including emotional liability, euphoria, depression, aggressiveness and insomnia, after ICS. Only eight such patients have so far been reported, suggesting that this is very infrequent and a causal link with ICS has usually not been established.
Based on extensive clinical experience ICS appear to be safe in pregnancy, although no controlled studies have been performed. There is no evidence for any adverse effects of ICS on the pregnancy, the delivery or on the foetus [ ]. It is important to recognise that poorly controlled asthma may increase the incidence of perinatal mortality and retard intra-uterine growth, so that more effective control of asthma with ICS may reduce these problems. Patients with COPD are elderly and are likely to have increased systemic side effects from ICS as they have several additional risk factors.
There have been fewer studies of systemic side effects in COPD patients. However, a systematic review found no reduction in bone mineral density or increase in fractures in COPD patients treated for up to 3 years with ICS [ 75 ].
An epidemiological study showed an increase in cataracts which are more common in an elderly population [ ]. Many patients with COPD suffer from co-morbidities, including hypertension, metabolic syndrome and diabetes, and may therefore have a worsening of these conditions, but this has not yet been systematically investigated.

Abstract Inhaled corticosteroids ICS are the most effective controllers of 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.
Mechanisms of Action There have been major advances in understanding the molecular mechanisms whereby ICS suppress inflammation in asthma, based on recent developments in understanding the fundamental mechanisms of gene transcription [ 1 , 2 ]. Table 1 Effect of corticosteroids on gene transcription. Open in a separate window. Cellular Effects At a cellular level inhaled corticosteroids reduce the numbers of inflammatory cells in asthmatic airways, including eosinophils, T-lymphocytes, mast cells and dendritic cells Figure 1.
Figure 1. Figure 2. Glucocorticoid Receptors Corticosteroids diffuse across the cell membrane and bind to glucocorticoid receptors GR in the cytoplasm 2. Figure 3. Switching off Inflammation 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 ].
Figure 4. Corticosteroid Resistance Patients with severe asthma have a poor response to corticosteroids, which necessitates the need for high doses and a few patients are completely resistant.
Figure 5. Figure 6. Pharmacokinetics The pharmacokinetics of ICS is important in relation to systemic effects [ 32 , 33 , 34 ]. Figure 7. Pharmacokinetics of inhaled glucocorticoids.
Clinical Use 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.
Figure 8. Use in Asthma As experience has been gained with ICS they have been introduced in patients with milder asthma, with the recognition that inflammation is present even in patients with mild asthma. Dose-Response Studies Surprisingly, the dose-response curve for the clinical efficacy of ICS is relatively flat and, while all studies have demonstrated a clinical benefit of ICS, it has been difficult to demonstrate differences between doses, with most benefit obtained at the lowest doses used [ 47 , 48 ].
Prevention of Irreversible Airway Changes in Asthma Some patients with asthma develop an element of irreversible airflow obstruction, but the pathophysiological basis of these changes is not yet understood.
Reduction in Mortality In a retrospective review of the risk of mortality and prescribed anti-asthma medication, there was a significant protection provided by regular ICS therapy [ 64 ]. Comparison between ICS Several ICS are currently on the market for use in asthma, although their availability varies between countries. Clinical Application in Asthma Patients ICS are now recommended as first-line therapy for all patients with persistent symptoms.
Add-on Therapy Previously it was recommended to increase the dose of ICS if asthma was not controlled, on the assumption that there was residual inflammation of the airways. Side Effects The efficacy of ICS is now established in short- and long-term studies in adults and children, but there are still concerns about side effects, particularly in children and when high inhaled doses are used.
Table 2 Side effects of inhaled corticosteroids. Local Side Effects Side effects due to the local deposition of the ICS in the oropharynx may occur with steroid, but the frequency of complaints depends on the dose and frequency of administration and on the delivery device used. Infections There is no evidence that ICS, even in high doses, increase the frequency of infections, including tuberculosis, in the lower respiratory tract in asthmatic patients. Systemic Side Effects The efficacy of ICS in the control of asthma is undisputed, but there are concerns about systemic effects of ICS, particularly as they are likely to be used over long periods and in children of all ages [ 33 , ].
