Abstract

Poor inhaler technique has been recognised as a significant contributor to poor control.(1) A number of authors have attempted to identify desirable attributes of an inhaler.(2,3) “Ease of use” is an important characteristic but is often determined after instructed training. Whilst the importance of initial and repeat correct inhaler technique training cannot be overlooked, a dry powder inhaler (DPI) device that is intuitively easy to use may be more beneficial for those patients with poor technique recall or with barriers to access adequate training. An intuitively easy to use inhaler such as the Sandoz Forspiro™ device may facilitate correct patient handling. A 28 day study to assess the intuitive ease of use of the Forspiro device was conducted in 24 Accuhaler® users (≥ 1 year use), aged 20–86 years (mean age = 53.8). Participants were separated into 2 groups of 12 and received either limited written instructions about the use of the device (Uninstructed) or were given fully illustrated instructions for use (Instructed). See table 1. The correlation of the ease of use assessment by Uninstructed and Instructed subjects has shown that the new Forspiro DPI is intuitive to use, even in patients that had received minimal instructions for use. The introduction of innovative generic versions of inhaled medications enables the much needed economic rationalisation of drug use in these times of austerity within the NHS. Benefitting from advanced design technology, drawn from years of patient feedback, generic versions of inhaled medications may be more readily adopted by patients and HCPs if the device is intuitive to use. The importance of initial and repeat correct inhaler technique training cannot be overlooked, however intuitively easy to use inhalers, such as the Forspiro device, may facilitate correct patient handling.
