Researchers from University of Parma provide details of new studies and findings in the area of bioadhesion
2007 NOV 21 -- According to recent research from Parma, Italy, "This paper describes an innovative transdermal drug delivery system, a monolaminated bioadhesive film in which the usual constituents of transdermal patches (backing, drug and adhesive) have been condensed in one, single layer, denominated Patch-non-Patch The main characteristics of the film is that it is not self-adhesive in the dry state but becomes adhesive only when applied on wet skin. This characteristic is due to the presence of a small amount of adhesive, unable to make the system self-adhesive, but capable of restoring the adhesiveness in contact with a small amount of water." "From the results obtained to date, it appears that the technology Patch-non-Patch (R) has the potentiality to be successfully applied to the pharmaceutical and cosmetic market. On the skin the film is flexible, invisible and adapts to all skin irregularities. The system has been shown to be highly efficient, releasing a high percentage of the active included in most cases. Additionally, the inclusion of other excipients can modulate drug delivery, thus improving the versatility of the product," wrote C. Padula and colleagues, University of Parma. The researchers concluded: "Finally, the second generation Patch-non-Patch (R), made occlusive on the skin surface, can further broaden the potential application." Padula and colleagues published their study in European Journal of Dermatology (Bioadhesive film for dermal and transdermal drug delivery. European Journal of Dermatology, 2007;17(4):309-312).
