In July 2018 Norwegian authorities decided to allow switch at pharmacy for dry powder inhalers (DPIs) containing budesonide-formoterol. Pharmacists are instructed to switch patients to the inhaler with the lowest price. The pharmacist will train the patient on how to use the new inhaler. All patients whose eligible inhaler switch occurred between 1st July 2018 and 1st March 2019 will be eligible for the study.
This is a retrospective, multicentre, non-interventional, observational study in patients with asthma and/or COPD who are treated with budesonide-formoterol.
