    • Biodegradable neurotoxin implants and methods of making and using such implants are provided. Biodegradable neurotoxin implants include a neurotoxin, a biodegradable polymer component, and an acidity regulating component. The biodegradable polymer component is effective in controlling the release of the neurotoxin from the implant when the implant is located in a patient's body. The acidity regulating component is effective in maintaining a pH of the implant in a desired range that may be effective in stabilizing the neurotoxin as the implant biodegrades when the implant is located in a patient's body. In one embodiment, an implant includes a botulinum toxin, a biodegradable polymer, and either monomers from which a biodegradable polymer is derived or oligomers including monomeric units substantially identical to a monomer from which a biodegradable polymer is derived, or a combination of such monomers and oligomers. The oligomers and biodegradable polymer may be derived from a single type of monomer. The implants disclosed herein may be administered to a human or animal patient in which a therapeutic effect is desired for prolonged periods of time.
    • 提供了可生物降解的神经毒素植入物和制造和使用这种植入物的方法。 可生物降解的神经毒素植入物包括神经毒素,可生物降解的聚合物组分和酸度调节组分。 当植入物位于患者体内时,可生物降解的聚合物组分有效地控制来自植入物的神经毒素的释放。 酸性调节组分有效地将植入物的pH保持在期望的范围内,当植入物位于患者体内时,当植入物生物降解时,稳定神经毒素是有效的。 在一个实施方案中,植入物包括肉毒杆菌毒素,可生物降解聚合物,以及衍生生物可降解聚合物的单体或包含单体单元的寡聚物,所述单体基本上与衍生可生物降解聚合物的单体相同,或这些单体和 低聚物。 低聚物和可生物降解的聚合物可以衍生自单一类型的单体。 本文公开的植入物可以施用于需要长时间治疗效果的人或动物患者。
