Polymer conjugates comprising a hydrophobic biodegradable polymer covalently attached to a mu opioid receptor (MOR) antagonist are described. Biodegradable covalent nanoparticles comprising the hydrophobic biodegradable polymer covalently attached to a MOR antagonist are provided as a vehicle for the sustained delivery of the MOR antagonist. The described MOR antagonist delivery system may be used to more effectively prevent or overcome the toxic effects of synthetic opioids.
