The objectives of this study were: (1) to assess the prevalence of and types of education methods provided to participants who use a metered-dose inhaler (MDI), (2) to determine the prevalence of MDI misuse in adults using objective and subjective assessments, and (3) to determine whether any associations exist between the education method and the participant's ability to properly use an MDI. ⋯ Although most participants received inhaler education, inhaler misuse was very common. No associations were found regarding method of education and proper inhaler technique.

Some recent salient publications related to inhaled drug therapy are discussed. Unexpectedly, a 2.5-μg once-daily dose of tiotropium (Respimat) had greater efficacy than the 5.0-μg daily dose. Occurrence of a reverse dose response serves to caution us that administering more drug is not always beneficial. ⋯ Also, inhaled antibiotics in patients with non-cystic fibrosis bronchiectasis and inhaled interferon-γ in patients with idiopathic pulmonary fibrosis have shown encouraging results but are investigational at this time. Compared to combustion cigarettes, use of e-cigarettes reduces exposure to carcinogens and volatile organic compounds. However, high levels of benzaldehyde in the vapor from cherry-flavored cigarettes raise concerns about the safety of some food flavorings in e-cigarettes.
