Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Randomised crossover trial of transdermal fentanyl and sustained release oral morphine for treating chronic non-cancer pain.
To compare patients' preference for transdermal fentanyl or sustained release oral morphine, their level of pain control, and their quality of life after treatment. ⋯ Transdermal fentanyl was preferred to sustained release oral morphine by patients with chronic non-cancer pain previously treated with opioids. The main reason for preference was better pain relief, achieved with less constipation and an enhanced quality of life.
