Tetracaine sustained-release material and preparation method thereof
The invention relates to the field of sustained-release materials, in particular to a tetracaine sustained-release material and a preparation method thereof. The sustained-release material comprises the following raw materials: tetracaine, polylactic acid, hexafluoroisopropanol and polyethylene glycol, and the mass ratio of tetracaine to polylactic acid is (1: 100)-(1: 1000); by designing the sustained-release material comprising tetracaine, polylactic acid, hexafluoroisopropanol and polyethylene glycol as raw materials, tetracaine in the sustained-release material stably exists in the polylactic acid, and meanwhile, the polylactic acid is a good biological material and has good affinity to human skin, so that the sustained-release material can be applied to the field of medical treatment. Compared with local anesthetic local injection, tetracaine and the like can be accurately and safely released at the affected part, the release process is a slow release process, the drug continuously plays a role in the local anesthetic process, and the drug poisoning risk existing in a local injection and one-time administration mode can be effectively reduced..
