A new formulation of the Allevyn foam dressings range has been developed. This report details the laboratory testing conducted in order to compare key performance attributes with the previous formulation. The results of these studies showed superior fluid handling performance. Consequently, a large clinical in-market evaluation has been initiated to determine how the formulation changes influence clinical performance, particularly in respect of fluid handling and the associated characteristics of wear time and maceration. These interim results confirm that this new formulation is superior to the previous one.
