For the 10-30% of patients with advanced cancer who experience intractable pain despite administration of large doses of morphine-like drugs by mouth or injection, more invasive dosing routes may be needed. This project will utilise innovative polymer chemistry to develop bioerodable prolonged-release polymer microparticles to deliver pain-killers into the spinal fluid near to the cells that mediate their actions, with a view to producing prolonged periods of analgesia in these patients.

对于10%-30%的晚期癌症患者，尽管口服或注射大剂量的吗啡类药物，但仍感受到顽固性疼痛，可能需要更多侵入性的给药途径。该项目将利用创新的聚合物化学来开发可生物可识别的缓释聚合物微粒，将止痛药输送到接近介导其作用的细胞的脊髓液中，以期在这些患者中产生更长时间的止痛期。
