Tailoring Inhaler Devices

Inhalation is the main route for administration of drugs for conditions such as asthma or chronic obstructive pulmonary disease. The advantage of administering drugs by inhaler is that drugs are delivered directly to the site of action within the airways. The onset of action is rapid and systemic adverse effects are minimised. However, for an inhaler to be effective the correct drug must be prescribed and the device must be used correctly. Poor inhaler technique is common. It is known that may patients with obstructive lung diseases use inhalers incorrectly.  Inadequate technique is associated with:-

• Poor symptom control
• Increased emergency visits
• Wasted resources with detrimental impact on the environment

Choosing a drug and a corresponding device the from large variety available is potentially confusing. National guidance recommends that the patient should have their ability to use the prescribed inhaler device (particularly for any change in device) assessed by a competent healthcare professional.  Unfortunately, inhalation of medicines can be complicated and difficult for many people, leading to suboptimal use and effect. The UK Inhaler Group have produced a set of standards to support HCPs.
