Mechanism of action

Fentanyl is a synthetic opioid that activates mu-opioid receptors throughout the brain and spinal cord, modulating pain perception and transmission. The intranasal formulation allows for rapid mucosal absorption, enabling faster onset of analgesia compared to oral routes. This is particularly useful for acute or breakthrough pain management in opioid-tolerant patients.
