A drug delivery patch developed at HP Labs is to be commercialised by Crospon, a medical device developer based in Galway in Ireland, in return for royalty payments.

Transdermal patches (which rely on absorption through the skin) for nicotine delivery have become a mainstay for smoking cessation programs; however, they have not been a widely effective delivery mechanism for many drugs because the skin acts as a natural barrier.
