Use in Paddle Over Disk Applications

Method

Transdermal or patch testing is carried out using USP method 5 (paddle over disc) or USP method 6, the rotating cylinder.

With paddle over disc, the transdermal patch is placed between a glass disc and an inert PTFE mesh. This is placed at the bottom of the vessel, with the mesh facing upwards, under a rotating paddle.

Unlike dissolution testing, transdermal testing is carried out at 32°C to reflect the lower temperature of the skin. Other variables such as the height setting and sampling requirements are the same as dissolution testing. APPFIVE-V35 has an outer diameter of 41.2mm and meets the diagram in the USP.
