The
Freeman Technology-sponsored prize for the best poster at December's
Powder Flow 2011 conference was presented to Hanne Kinnunen, a PhD
student at the University of Bath in the UK. Her presentation ‘The
impact of loaded drug dose and the surface roughness of the coarse
lactose carrier to the fluidisation characteristics of dry powder
inhaler formulations' was co-authored with Jag Shur and Robert Price,
also from the Pharmaceutical Surface Science Research Group in the
Department of Pharmacy and Pharmacology at Bath, and Gerald Hebbink from
DFE Pharma in Borcolo, The Netherlands.
The
primary aim of the work was to investigate the impact of increasing
drug concentration on the fluidisation properties of dry powder inhaler
(DPI) formulations prepared with carriers having different surface
characteristics. The results indicated that the fluidisation properties
of the formulations prepared with the carrier that had a higher degree
of surface roughness were less susceptible to change in fluidisation
properties when the concentration of the drug was increased.
Tim
Freeman, Director of Operations at Freeman Technology was part of the
judging team. "It was really pleasing to see a strong set of posters and
the judges certainly didn't have an easy task," he said. "Our
congratulations go to Hanne and I'd like to wish her every success with
her continuing research work."
Powder
Flow 2011 is a one-day conference that was held in London on 6
December, and followed a successful inaugural event in 2009. As well as
providing the £250 poster prize, Freeman Technology exhibited the FT4
Powder Rheometer at the event.
