Temperature-sensitive gel containing ropivacaine and used for long-acting injection and preparation method of temperature-sensitive gel
ActiveCN104606129AEasy to administerSimple preparation processAntipyreticAerosol deliveryLactidePh regulation
The invention discloses temperature-sensitive gel containing ropivacaine and used for long-acting injection and a preparation method of the temperature-sensitive gel. The gel comprises a main drug ropivacaine, ropivacaine hydrochloride or ropivacaine mesylate, a PLGA (poly (lactic-co-glycolic acid)) -PEG (polyethylene glycol)-PLGA copolymer as well as water, normal saline or pH regulation solution for injection, wherein the mole ratio of lactide to glycolide is (2-3): 1, and the PEG molecular weight of the PLGA-PEG-PLGA copolymer is 1,000. The preparation method comprises the following steps: the copolymer is sufficiently swelled in a solvent firstly, then the main drug is added, and sterilization is performed through a filter membrane. The temperature-sensitive gel facilitates drug delivery and can gel rapidly at human body temperature so as to play a slow release role, smaller than or equal to 35%-45% of the drug is released in vitro after 12 h, larger than or equal to 65%-75% of the drug is released after 48 h, larger than or equal to 80% of the drug is released after 72 h, and the design requirement for postoperative continuous analgesia for 48 h through single injection of a local anesthesia drug is met. Pharmacodynamics study shows that a temperature-sensitive gel group containing ropivacaine can prolong the efficacy maintaining time remarkably and continuously play 48 h analgesic effect.
