Steroid Inhalers: Usage Trends and Supply Issues
Steroid inhalers are widely used for managing asthma and chronic bronchitis. During the COVID-19 pandemic, there was a significant increase in demand for steroid inhalers in the UK, leading to distressing shortages and some products being listed as out of stock. This surge was attributed to people stockpiling inhalers out of concern for respiratory health during the pandemic .
Effectiveness of Steroid Inhalers in Asthma Management
Steroid inhalers are considered the mainstay for most asthma patients who need controller medications. However, there has been a notable increase in the prescription of combination inhalers (steroid plus long-acting beta agonist) in children, which is not always consistent with guidelines that recommend combination inhalers only for those not controlled on adequate doses of inhaled steroids alone .
For adults and adolescents with mild asthma, using a combination inhaler containing both a steroid and a fast-acting beta agonist as needed is clinically effective. This approach reduces asthma exacerbations, hospital admissions, and the need for systemic corticosteroids compared to using a fast-acting beta agonist alone. It is also as effective as regular steroid inhaler use, with the added benefit of lower average daily steroid exposure and no increase in adverse events Crossingham2021Crossingham2021Saul2022.
In more severe or persistent asthma, using a single inhaler for both maintenance and relief (containing formoterol and budesonide) can reduce the number of exacerbations requiring oral steroids or hospital visits compared to higher fixed-dose combination inhalers, while also lowering the total steroid dose .
Adherence and Inhaler Technique
Adherence to inhaled steroid therapy is a common challenge. Studies show that nearly half of patients may not use their inhalers as prescribed, and about a quarter have insufficient inhaler technique. Regular instruction and education from healthcare providers are crucial to improve both adherence and technique, which are essential for effective asthma and chronic bronchitis management .
Various interventions, such as adherence education, electronic reminders, and simplified drug regimens, can improve adherence to inhaled steroids. However, improvements in adherence do not always lead to clear clinical benefits in terms of asthma control or reduced exacerbations, highlighting the complexity of asthma management .
Side Effects and Risks of Steroid Inhalers
Steroid inhalers, especially dry powder inhalers (DPIs), can cause local side effects such as laryngitis. Computational studies show that DPIs with larger particle sizes tend to deposit more medication in the larynx, increasing the risk of laryngeal side effects. Choosing inhalers with smaller particle sizes may help reduce this risk .
Increasing Steroid Dose During Exacerbations
Increasing the dose of inhaled steroids at the onset of an asthma exacerbation does not appear to provide additional benefit in children with mild to moderate asthma. This practice does not improve peak flow rates, symptom scores, or overall outcomes, and therefore should not be routinely included in asthma self-management plans .
Conclusion
Steroid inhalers are a cornerstone of asthma and chronic bronchitis treatment, with strong evidence supporting their use as controller medications. Combination inhalers used as needed are effective for mild asthma and may reduce overall steroid exposure. Adherence and proper inhaler technique remain critical for optimal outcomes, and interventions to improve these factors can be beneficial. However, increasing steroid doses during exacerbations is not supported by evidence, and attention should be paid to potential local side effects, especially with certain inhaler types. Ongoing education for both patients and healthcare professionals is essential to ensure guideline-based, effective, and safe use of steroid inhalers.
