Inhaler devices for asthma: a call for action in a neglected field.

T he Brussels Declaration, published in the European Respiratory Journal in 2008 [1], recognises the high prevalence of patients with poorly controlled asthma and calls for changes in asthma management across Europe. Prescribing an appropriate inhaler device for asthma, a device that the patient accepts and can handle correctly, is one key element in this process. Inhaler mishandling is very common in real-world clinical practice and can contribute to poor asthma control [2–5].
