Un estudio multicéntrico conocido como IMPACT (Improving Asthma Control Trial), dirigido por médicos de la Universidad de California en San Francisco, concluye que los pacientes con asma leve persistente obtienen el mismo beneficio si reciben el tratamiento todos los días que si únicamente lo reciben únicamente durante las exacerbaciones. Evidentemente, los costes del tratamiento se reducen significativamente en el último caso.
Los resultados se publican en "The New England Journal of Medicine". En la revista se señala que el estudio no cuestiona la efectividad de los esteroides inhalados ni de otros fármacos como los antileucotrienos, que se consideran eficaces y necesarios para pacientes con asma moderada a grave. Sin embargo, consideran que en el asma leve tal vez no sea necesario.
