Step-Down Strategies for Asthma Management
Summary
Step-down strategies seek to reduce asthma treatment to the lowest effective intensity once stable disease control has been achieved. Such approaches typically involve tapering inhaled corticosteroid doses, withdrawing long-acting β2-agonists or other add-on therapies, or adopting adjustable maintenance regimens that respond to symptom fluctuations. The principal aims are to maintain symptom control, minimise adverse effects, enhance adherence and reduce healthcare costs. Optimal step-down requires regular assessment of lung function, exacerbation history and reliever use, together with patient education and shared decision-making. Recent work has emphasised personalised algorithms based on biomarkers or digital monitoring, while paediatric and older adult populations present distinct challenges owing to variable disease phenotypes and developmental considerations. Globally, judicious tapering aligns with sustainable prescribing and supports equitable access to essential medicines.

Step-Down Strategies for Asthma Management publication trend
The graph below shows the total number of articles in step-down strategies for asthma management across all publications each year (not limited to Nature Index journals).
Technical terms
Inhaled corticosteroids (ICS): Anti-inflammatory medications delivered by inhaler to reduce airway swelling and hyperresponsiveness.
Long-acting β2-agonist (LABA): Bronchodilator that relaxes airway smooth muscle for prolonged symptom relief, often used alongside ICS.
Exacerbation: Acute or subacute worsening of symptoms requiring additional treatment, such as oral corticosteroids or emergency care.
Step-down strategy: Planned reduction of asthma maintenance treatment intensity once control is achieved, aimed at balancing efficacy and safety.
