Abstract: Pellets containing an analgesic uniformly dispersed in a lipid carrier such as cholesterol mixed with fatty acid esters, can be used to provide long term pain relief. 5 mg cholesterol-tryglyceride-buprenorphine pellets released the majority of drug in 24-48 hours after implant and provide clinically significant plasma levels of analgesia in mice for 3-9 days. Blood levels of analgesia peak at day-1 and are substantially complete by day-5 depending on the level of buprenorphine. These results demonstrate that post surgical implants provide clinically significant levels of analgesia in the 24-48 hour period following surgery and thus obviate the time consuming, expensive, and high-risk need to inject mice post surgery. The pellets are safe and easy to use. Placed in the surgical wound at the end of surgery, they provide 2-3 days of analgesia and obviate the need for subsequent handling of the animal for pain therapy. The implants have no detectable effect on mouse behavior, hematology, or liver chemistry.
