Key points in effective inhaler technique training for asthma and COPD patients

Inhalation therapy involves two types of adherence: adherence to the drug and adherence to the procedures for the inhalation device. Recent increases in the range of inhaled medications available have expanded treatment options, while simultaneously resulting in more complicated treatments for patients due to the increasing diversity of inhalation devices. Patients with asthma and chronic obstructive pulmonary disease (COPD) are required to not only take the agent at the indicated dosage, but also use the inhaler device in the proper manner with correct procedures. This review presents eight key points for training patients with asthma and COPD in effective inhaler technique. These points can help to ensure a good balance of adherence to both the medication and the inhalation device, and thereby maintain disease control in clinical settings.
