Objective: Inhaler technique comprises a set of procedures for drug delivery to the respiratory system. The oral inhalation of medications is the first-line treatment for lung diseases. Using the proper inhaler technique ensures sufficient drug deposition in the distal airways, optimizing therapeutic effects and reducing side effects. The purposes of this study were to assess inhaler technique in pediatric and adult patients with asthma; to determine the most common errors in each group of patients; and to compare the results between the two groups. Methods: This was a descriptive cross-sectional study. Using a ten-step protocol, we assessed inhaler technique in 135 pediatric asthma patients and 128 adult asthma patients. Results: The most common error among the pediatric patients was failing to execute a 10-s breath-hold after inhalation, whereas the most common error among the adult patients was failing to exhale fully before using the inhaler. Conclusions: Pediatric asthma patients appear to perform most of the inhaler technique steps correctly. However, the same does not seem to be true for adult patients.
