Mechanism of action

Fentanyl is a synthetic opioid that crosses the blood-brain barrier and activates mu-opioid receptors, which modulate pain perception and emotional responses to pain. The intranasal formulation allows rapid absorption through the nasal mucosa, providing faster onset compared to oral administration, making it suitable for acute pain management and breakthrough pain in opioid-tolerant patients.
