Effectiveness of fentanyl buccal tablet for the treatment of breakthrough cancer pain. Review on pharmacokinetics, safety and clinical use in special situations.
Abstract
Several studies have shown that the prevalence of breakthrough pain in cancer patients is high and it is a problem not fully solved. Treatment of breakthrough cancer pain requires a drug with specific characteristics and probably the most useful drug is fentanyl, that is available in several formulations. This paper presents a review of published clinical trials on fentanyl buccal tablet to assess the evidence available regarding its effectiveness in the treatment of breakthrough cancer pain, issues related to its pharmacokinetics, safety and its use in special conditions such as mucositis. Evidence shows that fentanyl buccal tablet is effective for relieving pain in the treatment of episodes in breakthrough pain, including patients with mucositis. The bioequivalence of buccal (between the gum and cheek) and sublingual (under the tongue) administration has been also reviewed.Downloads
