I am a pharmacy technician and I am trying to find some legitimate studies that have evaluated the effectiveness of the generic fentanyl transdermal patches compared to the name brand Duragesic patches. Also, some studies that might include comaprisons of the generic patches made by different manufactures (Sandoz vs. Mylan). Any help or points in the right direction would be appreciated![:I]
