Metered dose inhalers; errors in the use in Asthma and COPD.
Professional Med J Jan ;11(1):63-7.

Metered dose inhalers are the most effective, cheaper and safer method of delivering drug to the patients with asthma and COPD. Errors in inhalational technique compromise their use and efficacy. In the study 400 consecutive patients coming to outdoor of Allied Hospital Faisalabad, who ever had used MDIs were asked to perform inhalational technique and most common errors were observed. They were followed up for 8 weeks and those who remain untrained after 8 visits were declared non trainable and accessory devices (spacer device) were added to MDIs. Errors were observed in every age group but generally speaking, percentage of error was more in old people and more in females. It was observed that it is difficult to train old patients and females. Moreover it was observed that patient education and demonstration of inhalational technique is corner stone in proper use of MDIs.
