A sustained-release microsphere produced by enclosing a hydrophobic antipsychotic such as bromperidol or haloperidol in a base comprising a biocompatible polymer such as polylactic acid or a lactic acid/glycolic acid copolymer. It can exhibit a desired pharmacological effect, where a long-term administration is necessary, by injecting once every 1 to 8 weeks instead of every day. As a result, a remarkable improvement can be expected in the compliance during maintenance therapy. In addition, the use of the biocompatible polymer serves to entirely dispense with surgical operations such as implantation, facilitates hypodermic and intramuscular injection just like the case of suspending injection, and can dispense with the widrawal of the microsphere. Furthermore, the microsphere can be administered with little aversion and pain.
一种缓释微球,将溴哌利多或氟哌啶醇等疏水性抗精神病药物包裹在由聚乳酸或乳酸/乙醇酸共聚物等生物相容性聚合物组成的基质中。在需要长期用药的情况下,只需每 1 至 8 周注射一次,而不是每天注射一次,就能发挥理想的药理作用。因此,可望显著改善维持治疗期间的依从性。此外,使用生物相容性聚合物可以完全省去植入等外科手术,方便皮下注射和肌肉注射,就像悬浮注射一样,还可以省去微球的拉伸。此外,施用微球时几乎不会产生厌恶感和疼痛感。
