Breakthrough pain (BTP) is an unmet clinical need that is still poorly diagnosed, evaluated and inadequately treated. The prevalence of BTP has been estimated to affect at least 64% of cancer patients. Two pain-relief strategies were proposed: preventive and active ('rescue'). ⋯ Fentanyl buccal tablet (FBT) is a novel delivery system for fentanyl citrate. FBT utilizes OraVescent technology to improve bioavailability and speed of drug delivery. Recent studies have demonstrated superior pharmacokinetic profiles when compared with other available transmucosal opioids (OTFC), however, pharmacodynamic data are still somewhat limited.
