  • Patent number: 10154968
    Abstract: Stable nanoparticle compositions comprising buprenorphine and at least one biodegradable polymer. The disclosure also provides methods of controlling pain in an animal and methods of treating addiction in a human utilizing the stable nanoparticle compositions, as well as pharmaceutical formulations comprising the stable nanoparticle compositions. The stable nanoparticle compositions are capable of releasing buprenorphine over several days, weeks, or months following administration. The stable nanoparticle compositions of buprenorphine utilize biodegradable polymers capable of degrading into non-toxic components in the body of an animal and may be excreted in the urine of the animal following their metabolism in the body. The stable nanoparticle compositions can advantageously provide sustained release of buprenorphine in the body after a single administration without the need for surgical removal of implanted matrices subsequent to depletion of the drug.
