Drug Names(s): NKTR-181
Description: NKTR-181 is a novel mu-opioid analgesic investigational drug candidate engineeredusing Nektar's small molecule polymer conjugate technology. NKTR-181 has beendesigned to enter the central nervous system (CNS) at a substantially lower ratecompared to existing opioid therapies. By slowing the entry of the drug into theCNS, NKTR-181 has the potential to eliminate not only the euphoria that underliesopioid abuse liability and dependence, but also the serious CNS-related side effectsof respiratory depression and sedation. The unique molecular design of the polymerconjugate also prevents conversion of NKTR-181 into a free opioid or an abusable formof an opioid.
