Critical inhaler errors in asthma and COPD: a systematic review of impact on health outcomes

BACKGROUND Inhaled drug delivery is the cornerstone treatment for asthma and chronic obstructive pulmonary disease (COPD). However, use of inhaler devices can be challenging, potentially leading to critical errors in handling that can significantly reduce drug delivery to the lungs and effectiveness of treatment. METHODS A systematic review was conducted to define 'critical' errors and their ...

A cross-sectional observational study to assess inhaler technique in Saudi hospitalized patients with asthma and chronic obstructive pulmonary disease

OBJECTIVES To assess the proportion of critical errors committed while demonstrating the inhaler technique in hospitalized patients diagnosed with asthma and chronic obstructive pulmonary disease (COPD).  METHODS This cross-sectional observational study was conducted in 47 asthmatic and COPD patients using inhaler devices. The study took place at King Abdulaziz Medical City, Riyadh, Saudi Ara...

Endemic asthma inhaler abuse among antisocial adolescents.

BACKGROUND Approximately 40 million prescriptions were dispensed in the U.S. for asthma inhalers in 2006. Although the pervasive distribution of asthma inhalers warrants greater attention to possible misuse of these products, few investigations have examined asthma inhaler misuse. The purpose of this study was to describe the prevalence, correlates and consequences of asthma inhaler misuse amon...

Fine particle mass from the Diskus inhaler and Turbuhaler inhaler in children with asthma.

The study aimed to investigate dose consistency and particle distribution from the dry powder inhalers Diskus and Turbuhaler. Full profiles of inhalation pressure versus time were recorded in 18 4 yr old and 18 8 yr old asthmatic children through Diskus and Turbuhaler inhalers. These data were used in an inhalation profile simulator to assess drug delivery from both a Diskus inhaler and a Turbu...
