Multicenter Study Clinical Trial
Transdermal buprenorphine in the treatment of cancer and non-cancer pain - the results of multicenter studies in Poland.
This was a multicenter, non-interventional, post-marketing study that aimed to evaluate the analgesic activity, safety of use, safety profile and adverse drug reactions of transdermal buprenorphine (Transtec 35, 52.5 and 70 μg/h) during the treatment of moderate to severe chronic cancer and non-cancer pain. The study was performed in Poland by 339 doctors. The study involved 4,030 general practice outpatients (managed by primary care physicians), pain therapy center patients, specialist outpatient clinic patients as well as patients treated in inpatients units. ⋯ Patients were enrolled if their pain was not well-controlled after using non-opioid analgesics. Another objective of the study was to monitor adverse drug reactions of transdermal buprenorphine reported by patients or noted by the doctors during the study visits. This first such multicenter study in Poland has confirmed high efficacy and good tolerability of buprenorphine and, therefore, confirmed its usefulness in the treatment of moderate to severe cancer pain as well as in the treatment of severe pain in patients with non-cancer pain that cannot be effectively treated with non-opioid analgesics.
