Texture: Transdermal Delivery Systems
6 May 2013Transdermal Drug Delivery Systems (TDDS) are a fundamental part of novel drug delivery systems. This application note describes use of the Brookfield CT3 Texture Analyzer to quantify the tack performance of a transdermal delivery patch. This is measured as the adhesive force required to break contact between the probe surface and adhesive of the patch using a ball probe.
