Pharmacodynamics and clinical efficacy of fentanyl iontophoretic transdermal system for post-operative pain in hospitalized patients.

Introduction: The fentanyl iontophoretic transdermal system (ITS) is a patient-controlled transdermal system allowing needle-free administration of on-demand doses of Fentanyl of 40 µg over a 10-min period up to 80 doses or over a 24-h period. It is indicated in opioid naïve patients for the treatment of acute postoperative pain in the hospitalized patients for up to 72 h.

Areas Covered: It has been demonstrated to be effective and safe in randomized trials and to provide comparable analgesia versus morphine intravenous (i.v.) patient-controlled analgesia (PCA) with adverse events similar between groups.

Expert Opinion: Fentanyl ITS has shown high patient satisfaction rates, and was described by patients and investigators as easy and convenient to use. These properties make this technology interesting when considering perioperative pain management. In the present health care environment additional data are required to establish the cost-benefit ratio of this technology in optimizing patient's recovery from surgery.
