INHALER USE IN CHRONIC OBSTRUCTIVE PULMONARY-DISEASE

Inhaler technique is a common problem, particularly in the elderly. We have assessed the ability to use seven common inhaler devices in 20 p atients with chronic obstructive pulmonary disease (COPD). Techniques were taught in a standard fashion in random order and assessed immedia tely and one hour later by two observers. Fourteen patients had a faul t that would result in no drug delivery at some time during the study, and such a fault occurred at some point for each inhaler device. Thes e faults were most common with the diskhaler. Accuhaler, autohaler and turbohaler scored highest and diskhaler lowest. Overall scores declin ed by one hour after instruction. Patients ranked the metered dose inh aler and accuhaler highest for ease of use and preference. These resul ts show that it is useful to have a small range of devices for patient s with COPD and that it is important to review inhaler technique regul arly.
