Mechanism of Action: How it Works

Fentanyl is a pure opioid agonist that binds primarily to the mu-opioid receptors in the main nerve system (brain and spine).

Absorption: Upon positioning under the tongue, the tablet liquifies in the saliva. The extremely lipophilic (fat-soluble) nature of fentanyl enables it to pass quickly through the mucosal membrane.
