Mechanism of Action
The patch includes a drug-containing adhesive matrix or a tank system that releases fentanyl at a constant rate through the skin into the bloodstream. As soon as applied, the skin under the patch absorbs the medication, and a "depot" of fentanyl forms in the upper skin layers. From there, the medication enters the systemic flow, offering a stable level of analgesia.
