Multicenter Study Clinical Trial Controlled Clinical TrialA clinical evaluation of transdermal therapeutic system fentanyl for the treatment of cancer pain.
Fentanyl has been incorporated into a transdermal therapeutic system (TTS) containing a rate-limiting membrane that provides constant release of the opioid. TTS fentanyl provides continuous opioid delivery for up to 72 hr without the need for special equipment. After Institutional Review Board approval, 53 patients with cancer pain requiring 45 mg or more of oral morphine daily were admitted into an open-label, prospective, multicenter evaluation of TTS fentanyl for the relief of pain. ⋯ Side effects considered related to the fentanyl patch were nausea (13%), vomiting (8%), skin rash (8%), and drowsiness (4%). Thirty percent of patients reported adverse experiences related to the fentanyl patch, and 17% had to be discontinued from the study. We conclude that TTS fentanyl administered every 3 days for the treatment of cancer pain is effective, safe, and well tolerated by most patients.
