BackgroundIn a non-interventional study the efficacy and tolerability of oral transmucosal fentanyl citrate (OTFC) was studied in patients with opioid-treated cancer pain suffering from breakthrough pain.Patients And MethodsThe prospective multicenter observational trial included 406 patients. For 3-4 months, efficacy of OTFC treatment for breakthrough pain was documented using a numerical analog pain intensity scale (NAS). Further, OTFC therapy was rated and adverse events were recorded.ResultsWith application of oral transmucosal fentanyl citrate median pain intensity fell from NAS 8 points at the beginning to NAS 2 points at the end of the study. The median effective dosage was 400 g. Tolerability was rated as good or very good by 87.5% of the patients.ConclusionOral transmucosal fentanyl citrate is a safe and effective treatment for breakthrough pain in chronic cancer-related pain.
