The timing is more important than the total dose of inhaled corticosteroid in mild asthma

In asthma care, inhaled steroids treat the inflammation driving symptoms, and β2-agonists like Salbutamol relieve symptoms quickly to make breathing easier. We found that by taking these medicines together in a combined inhaler early when symptoms started to flare up, patients were able to better match the amount of steroid taken to their need (rather than taking a fixed daily amount). This resulted in fewer severe asthma exacerbations, a lower overall steroid dose, and fewer days in which they needed to take their inhaler at all.

Our key take-home message is that “the timing of ICS dose when self-titrated to β2-agonist use, through the as-needed use of the combination budesonide/formoterol inhaler, is more important than total ICS dose in reducing severe exacerbation risk in mild asthma.”
