Abstract

The invention belongs to the technical field of injection production, and particularly relates to a ropivacaine hydrochloride sodium chloride injection and a preparation process. The ropivacaine hydrochloride injection comprises 0.40 g of ropivacaine hydrochloride and 1.72 g of sodium chloride in every 200 ml of the ropivacaine hydrochloride injection, and injection water is added to 200 ml of the ropivacaine hydrochloride injection. In addition, the preparation device comprises a machine body assembly, an injection storage box, a sterile filling mechanism, a cover pressing mechanism and a control box, the sterile filling mechanism comprises a conveying pump, the conveying pump is connected with a liquid conveying main pipe, and the lower end of the liquid conveying main pipe is connected with a plurality of liquid conveying branch pipes at intervals; the ropivacaine hydrochloride sodium chloride injection provided by the invention is clear in drug effect and high in safety, determination results of various indexes in a stability test all meet regulations, and the preparation device ensures the product quality of the prepared injection, so that the drug effect of the injection is clear, and the safety is high.

Description

technical field [0001] The invention belongs to the technical field of injection production, in particular to a ropivacaine hydrochloride sodium chloride injection and a preparation process. Background technique [0002] Ropivacaine is the first synthetic pure isomer of new long-acting amide local anesthetics. Its pharmacological properties are low cardiotoxicity, more obvious separation of sensory block and motor block, and vasoconstriction. Ropivacaine has dual effects of anesthesia and analgesia. High concentrations can produce surgical anesthesia, while lower concentrations can effectively block sensory nerve transmission and produce analgesic effects. It has less effect on motor nerves. Therefore, ropivacaine It is a safe and effective local anesthetic in clinical application and has high application value. The current existing ropivacaine hydrochloride injection has the problem of poor stability due to insufficient preparation technology. [0003] In addition, the ex...
