Breakthrough pain management using fentanyl buccal tablet (FBT) in combination with around-the-clock (ATC) opioids based on the efficacy and safety of FBT and its relationship with ATC opioids: results from an open-label multi-center study in Japanese cancer patients with detailed evaluation

摘要

ObjectiveRapid analgesic onset opioids, particularly fentanyl buccal tablet, is preferable for managing breakthrough pain. The efficacy and safety of fentanyl buccal tablet and its association with around-the-clock opioids needs to be explored with an option of dose adjustments, more closely reflecting administration in clinical practice. The aim of the study was to assess the safety and efficacy of fentanyl buccal tablet in breakthrough pain management in combination with around-the-clock opioids with the dose adjustment option, and explore the dose adjustment's influence on breakthrough pain management using detailed evaluation.
