Duragesic patches

[blakmike]

Hi,

I'm used to abusing Duragesic 50 mcg/hr patches, but am soon getting a couple of 100 mcg/hr ones.

My question is does the 100 have twice as much gel as the 50? or is the same amount of gel at double the concentration?

yes, it has twice the content and delivers twice as much.

Dose*(mcg/h) - Size(cm2) - Fentanyl Content(mg)

12† - 5.25 - 2.1
25 - 10.5 - 4.2
50 - 21 - 8.4
75 - 31.5 - 12.6
100 - 42 - 16.8


* Nominal delivery rate per hour
† Nominal delivery rate is 12.5 mcg/hr
