Mechanism of action

PecFent (fentanyl pectin nasal spray) is a potent mu-opioid receptor agonist formulated for rapid transmucosal absorption via the nasal cavity, providing fast-acting pain relief. Epistatus (midazolam oromucosal solution) is a benzodiazepine that enhances GABAergic inhibitory neurotransmission in the central nervous system, rapidly terminating acute seizures. Both are designed for rapid onset of action via non-intravenous routes.
