Background Description/Mechanism of Action Naloxegol is an antagonist of opioid binding at the mu-. When administered at the recommended dose levels, naloxegol functions as a peripherally-acting mu-opioid receptor antagonist in tissues such as the gastrointestinal tract, thereby decreasing the constipating effects of .

Naloxegol is a PEGylated derivative of , and is a substrate for the P-glycoprotein transporter (P-gp). Also, the presence of the PEG moiety in naloxegol reduces its passive permeability as compared with naloxone. Due to the reduced permeability and increased efflux of naloxegol across the blood-brain barrier, related to P-gp substrate properties, the CNS penetration of naloxegol is expected to be negligible at the recommended dose levels limiting the potential for interference with centrally mediated opioid analgesia.

FDA Approved Indication Movantik is FDA approved for the treatment of agonist-induced constipation in adult patients with chronic non-cancer pain.
