he's got it backwards. mg for mg
fentanyl (the opiate in
duragesic patches) is MUCH more potent than IV
morphine, w/ fentanyl being active in the MICROgram range. Beyond that, oral morphine is considerably less potent than IV, w/ approx a 30% loss of the product compared to an equilivant IV dose (orally morphine is active around 5mg). The duragesic patch is a controlled Time release transdermal delivery system, and I'm not sure how effective it is in getting fentanyl into your bloodstream or how much it releases at a time, but the active ingredient is much stronger than morphine.
