Paddle Over Disk (USP-5)

With paddle over disc, a transdermal patch is placed either between a glass disc and an inert PTFE mesh, or directly onto a stainless steel mesh. This is placed at the bottom of the vessel, with the mesh facing upwards, under a rotating paddle. Transdermal testing is carried out at 32°C to reflect the temperature of the skin. Other variables such as the height setting and sampling requirements are the same as for USP Method 2.
