24 October 2012; Nottingham, UK: Drug Delivery to the Lungs 23 (DDL23), 5th –7th December 2012, (Edinburgh, UK) marks the first European outing for the BRS 3000, a powerful new breathing simulator from Copley Scientific that is designed specifically to support more representative testing for dry powder and metered dose inhalers (DPIs and MDIs). Visit the Copley Scientific stand to find out how the BRS 3000 can help to secure a greater understanding of OIP performance and for informed debate on how to achieve better in vitro in vivo relationships.
More representative testing, an important goal in inhaled product testing, focuses attention on the breathing profiles applied during in vitro measurement, which are typically square wave functions. The BRS 3000, in contrast, allows users to precisely define and apply breathing profiles that mimic those of a patient and can be used to generate either dose uniformity or aerodynamic particle size distribution data (measured by cascade impaction). In combination with other tools, such as the Alberta Throat and mixing inlets, the BRS 3000 allows users to closely tailor their testing in order to ensure maximum relevance and to gain deeper insight into DPI and MDI performance.
The BRS 3000 permits the application of user-defined flow rate versus time profiles as well as standard sinusoidal, rectangular and triangular waveforms. It offers precise control over inhalation/exhalation ratio, breath volume (up to 5 litres), breathing duration and breaths per minute. With a maximum flow rate of 240 L/min and a acceleration up to 25 L/s2 (free flow) it fully meets the exacting demands of both MDI and DPI testing, where powerful inhalation-only manoeuvres are applied during use.
