Inhaler Devices: The past, the Present, and the Future

Inhaler handling errors negatively impact asthma control and represent one of the most common challenges in asthma management. Overcoming inhaler handling errors can be achieved by increased awareness of errors, more explicit and consistent training in inhaler use, and development of ‘intuitive’ devices. Clinical studies have shown that dry powder inhalers (DPIs) have better dose consistency and delivery to the lungs, but this is also dependent on device and inhalation technique. In addition, recent clinical studies have demonstrated that Spiromax® is a more intuitive device than Turbuhaler®. In studies analysing patient device mastery, intuitive devices are preferred by patients because they are easy/simple to use and have effective dose delivery.
