Abstract (en)

[origin: WO2022198167A1] Microsphere formulations comprising naltrexone are provided. The microsphere formulations comprise polymer microspheres, each polymer microsphere comprising: (i) naltrexone; and (ii) a biodegradable polymer comprising a POE or a PLA, wherein each polymer microsphere comprises a drug load of naltrexone of at least 40% by weight of the polymer microsphere, and wherein the polymer microspheres have an average particle size of about 25 mm to about 55 mm (D50). Methods for making and using the microsphere formulations are also provided.
