A recent research study findings revealed that more than 25% of the people who are suffering through asthma or chronic pulmonary diseases are not using their dry powder inhalers in correct way. This wrong inhaling reduces the effectiveness of all the treatments.

This research was conducted in the leadership of Dr Antoine Magnan at the ‘University of Nantes’ in France. Dr Magnan and his colleague researchers explained that dry powder inhalers containing medication are common and very popular among the majority of the patients with asthma and chronic obstructive pulmonary disease. Researchers observed that, “The effectiveness in delivering drugs to the lungs depends on correctly performed inhalation maneuvers”.

Dr. Antoine Magnan and his team of researchers collected the results of almost 50 studies that were conducted previously by several researchers. These results were analyzed and reviewed. Evaluation of commonly adopted inhaling techniques applicable in patients with respiratory diseases enabled them to observe and highlight the most common errors made by patients when using these devices.

Findings of this evaluation show that almost 94% of the patients whose medical data and practices were studies were not using their inhalers correctly. This analysis depended on the type of inhaler and particular method of assessment.

According to the researchers, among the most common mistakes, not breathing out before using the inhaler, not holding the breath after inhalation, and failing in breathing deeply enough when inhaling the medication are the most common ones.
The study reveals that many participants demonstrated improper inhaler techniques and almost 25% of them never got any type of instructions for using the inhaler in right way.

Even the patients who received proper instructions about using the inhalers correctly did not have any idea about the quality and duration of their instructions. Doctors also did not care for conducting adequate reviews and follow up checks subsequent to the medications.

Researchers reported the results of their study in the journal “Respiratory Medicine” and explained that a large population of patients is committing errors in dealing with the dry powder inhalers and this may also increase the risks of insufficient drug delivery. Such a situation will, researchers say, adversely affect the drug efficiency and would possibly lead to” inadequate control of asthma and chronic obstructive pulmonary disease”.
