Abstract
Matrix systems for transdermal fentanyl will replace the reservoir systems in Europe. In an industry-independent, prospective, multicenter pilot study, 46 outpatients with chronic pain were asked to assess pain intensity, sleep interference, adverse events, and multiple secondary parameters during administration of the last reservoir and the first two matrix patches. There was no difference in pain intensity, sleep interference, and the rate of adverse events between both systems. Self assessment on a 6-step numeric rating scale (1 = very good, 6 = insufficient) comparing the two systems (reservoir vs. matrix) showed that skin compatibility (2.6 vs. 1.5), adhesive properties (3.2 vs. 1.8), wearability/comfort (2.8 vs. 1.5), and general satisfaction (2.5 vs. 1.8) improved significantly with the new matrix technology. At study endpoint, 91% of patients preferred the matrix system for future use. The new fentanyl matrix system is characterized by a high level of general satisfaction, ease of use, patient acceptance, and improved skin compatibility. Reservoir and matrix systems appear to have comparable efficacy and safety so that outpatients can be switched directly from the reservoir to the matrix system without difficulties and new dose titration.
