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.

Paddle Over Disc
With paddle over disc, a transdermal patch is placed either between a glass disc and an inert PTFE mesh (APPFIVE-HR), or directly onto a stainless steel mesh (APPFIVE-V35, APPFIVE-V56 and APPFIVE-V80). 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. The USP 5 apparatus is compatible with all brands of dissolution bath.
