Application of combination of polyethylene glycol and local anesthetic in non-narcotic analgesia |
abstract |
The invention discloses use of a conjugate of polyethylene glycol and a local anesthetic in non-anesthetic analgesia. A local anesthetic is prepared into a prodrug or a sustained release preparation, wherein a high molecular polymer such as polyethylene glycol in the prodrug is covalently bonded with a local anesthetic, and auxiliary materials with a sustained release effect in the sustained release preparation are non-covalently bonded to the local anesthetic. After administration, there is no anesthesia and analgesic effect before the release of the free local anesthetic. After the free local anesthetic is released, an analgesic effect is achieved. And the prodrug or the sustained-release preparation of the local anesthetic of the present invention releases the drug slowly, and renders the drug concentration kept stable and long-lasting in the effective concentration range of non-narcotic analgesia, and the long-acting non-anesthetic analgesic effect can be achieved while significantly reducing the clinical adverse reactions of local anesthetics and reducing the number of administrations. The effectiveness of the drug is greatly enhanced and the clinical application range of local anesthetics is expanded. |
