increasing transdermal bioavailability of Ketamine?

[PoppyLlama]

Hey all, I have been searching for an answer but have not been able to find much information. Does anyone know of a way to increase the transdermal bioavailability of Ketamine? I have a cream for my back that is helping some, but I would like to have a little more absorption to help even more. Advice? I also have arm pain would it help increase BA of Ketamine to rub it over a vain as opposed to another part of the skin?

could cleaning the area with rubbing alcohol or anything like that up the BA?

thanks for your help to whoever helps
