Principles of the use of inhaler devices in asthma treatment

초록

Background: Inhaler therapy is the most critical route of administering drugs in the management of asthma due to its rapid onset of action, better pulmonary efficacy, and reduced risk of side effects, compared with other routes of administration. Current Concepts: Although many physicians and patients believe they know how to use inhaler devices, most do not know the correct techniques. To achieve better and more effective treatment results, the inhalation device should be appropriate for the characteristics and wishes of each patient. Available inhaler devices include pressurized metered dose inhalers, dry powder inhalers, soft mist inhalers, and nebulizers. To improve disease outcomes and treatment adherence, a personalized stepwise approach, based on each patient’s conscious inhalation, inspiratory flow, and hand-lung coordination, is recommended in the selection of the most appropriate device. Discussion and Conclusion: Common problems with inhaler usage include failure to exhale completely before inhaling, insufficient inhalation efforts, and inadequate breath-hold after inhalation. Therefore, continuing education and support are warranted to ensure optimal outcomes and enable patients to improve inhaler usage techniques. Health care providers should also know the devices and develop systems in order to provide comprehensive support to patients in clinical practice.
