Does use of a corticosteroid/long-acting beta-agonist combination inhaler increase adherence to inhaled corticosteroids?

This 12-month retrospective pilot study analysed prescription data of 82 patients with asthma from six practices in Norfolk. Patients on an inhaled corticosteroid/long-acting beta-agonist combination inhaler had significantly greater adherence to inhaled corticosteroids compared to those on a corticosteroid inhaler alone (76.7% versus 40.0%, p=0.001).
