Phosphagenics intends to change the adhesive in its TPM/oxycodone pain relief patch to resolve an issue with crystallization. The Melbourne-based drug delivery company recently disclosed that researchers are testing alternatives to the proprietary adhesive developed by 3M and currently used in the patches. In vitro testing so far has shown that the alternatives demonstrated increased oxycodone delivery, without the crystallization. Phosphagenics announced last month that Germany's Labtec GmbH was helping to work out the prototypes' minor crystallization problems for the patch's final design. Phosphagenics now plans to design the final patch exclusively with Labtec, but says that it will continue to work with 3M in all other respects. Labtec specializes in opioid patch development and designed the current best-selling fentanyl patch in Germany.
