The invention relates to the field of analgesics. According to the invention, a kit or composition, particularly a pharmaceutical composition or a pharmaceutical kit, is provided, comprising a nanocarrier which is a hyperbranched polymer, such as a dendritic polymer or dendrimer, preferably having a molecular weight of 1,000-100,000 g/mol, and an analgesic which, when administered without nanocarrier, has both peripheral and central analgesic effect, preferably an opioid such as nalbuphine. According to the invention, the analgesic in this composition mainly or exclusively has a peripheral effect and thus reduces side effects triggered by the activation of central or intestinal opioid receptors. It is used for the treatment of peripheral pain and/or inflammation. The invention also relates to particularly suitable nanocarriers.
本发明涉及镇痛剂领域。根据本发明,提供了一种试剂盒或组合物,特别是一种药物组合物或药物试剂盒,其中包括一种纳米载体,它是一种超支化聚合物,如树枝状聚合物或树枝状聚合物,优选分子量为 1,000-100,000 g/mol;以及一种镇痛剂,当不使用纳米载体时,该镇痛剂具有外周和中枢镇痛效果,优选阿片类药物,如
纳布啡。根据本发明,该组合物中的镇痛剂主要或完全具有外周效应,从而减少了因激活中枢或肠道阿片受体而引发的副作用。它可用于治疗外周疼痛和/或炎症。本发明还涉及特别适用的纳米载体。
