Mechanism of action

Fentanyl and morphine are synthetic and natural opioids, respectively, that activate mu opioid receptors throughout the brain and spinal cord, inhibiting pain signal transmission and producing analgesic effects. The E-TRANS transdermal patch technology enables continuous, controlled delivery of these opioids through the skin, maintaining steady-state plasma concentrations and providing prolonged pain management without frequent dosing. This delivery system reduces fluctuations in drug levels compared to immediate-release formulations.
