Duragesicとは 意味・読み方・使い方

Duragesic and Durogesic (pronounced /ˌdɜrəˈdʒiːzɪk/) are trade names of fentanyl transdermal therapeutic systems, and are used for relief of moderate to severe pain. Since Duragesic/Durogesic release Fentanyl, a potent opioid, slowly through the skin, one patch may provide 72 hours of pain relief. Its initial onset after a patch has been applied is roughly 8–12 hours under normal conditions, thus Duragesic patches are often prescribed with another opioid (such as morphine sulfate) to handle breakthrough pain.
