The 1/25/05 update of late stage drug development also shows under Pain Management: DURAGESIC 12 C11(fentanyl transdermalsystem) with a filing of 4/2004, and IONSYS (fentanyl HCl patien-controlled transdermal analgesic)in Phase lll
Duragesic 12 is the long awaited lowest dose. A lot of physicians had complained that 25 mcg was too high of a dose to start naive-opiod patients on. But Duragesic 12 is too late to really have any impact on the market.
Besides, the major difference between Duragesic and Mylan's product is that Duragesic is a resevoir-patch, while Mylan's patch is a matrix-patch. So you can cut Mylan's patch all you want and it can be used. You cannot cut Duragesic at all.
