NKTR-181 is an analgesic opioid molecule which exhibits a reduced incidence of specific CNS-mediated side effects, such as euphoria, through the targeted alteration of brain-entry kinetics.
The molecular structure of NKTR-181 is designed to have low permeability across the blood-brain barrier in order to slow its rate of entry into the brain and attenuate the dopamine release that underlies euphoria.
Nonclinical and clinical data show that the inherent properties of NKTR-181 reduce its rate of entry into the brain compared to standard mu opioids, regardless of route of administration.
In addition, NKTR-181 has a 14-hour elimination half-life to enable twice-daily dosing for pain control.
