A new once-a-day fentanyl citrate patch (Fentos Tape) could be a new treatment option in patients with end-of-dose failure using a 72-h transdermal fentanyl matrix patch.

Purpose: The recommended dosing interval for transdermal fentanyl is every 72 h. However, some patients will have "end-of-dose failure," which may be seen as an increase of episodes of severe pain flares at the third day after application of the patch. A new once-a-day fentanyl patch was developed in Japan since 2010.
