Problems solved by technology

A technical problem is that the current domestic injection ampoule packaging bottle is made of neutral glass, which is commonly referred to as Grade B material. The chemical stability and thermal stability of neutral glass and the ability to withstand temperature changes are relatively poor. Strong acid and strong alkaline liquids are prone to "flaking off" phenomenon, while the pH value of ropivacaine mesylate injection is 4.0-6.0, which requires the packaging bottle to be acid-resistant and not chemically react with the liquid. Some ampule packaging bottles a

Abstract

The invention relates to a preparation method of ropivacaine mesylate injection packed by a soda-lime glass bottle, which comprises the following processing steps of ingredient preparation, liquor preparation, soda-lime glass bottle and rubber plug cleaning, filling, capping, sterilization, lamp test, labeling, packing and finished product inspection. The injection is subject to a filtration sterilization processing step once and a flowing steam sterilization processing step once, wherein microorganisms larger than 0.22 microns in liquid medicine are removed by a filter method, microorganismssmaller than 0.22 microns are killed by flowing steam sterilization, and insoluble particles in the liquid medicine are removed during filtration sterilization simultaneously, thereby greatly reducingthe occurrence of phlebitis; and the invention is packed by the soda-lime glass bottle which has the advantages of heat resistance, acid and alkali resistance, large strength, and the like, thereby ensuring the stability of the medicine. Clinic comparison tests show that the ropivacaine mesylate injection packed by a soda-lime glass bottle has the advantages of quicker effect, long action time, reliable anesthetic effect, small toxicity to heart, separate blocking pf sensory and motor nerves, and the like, thereby being suitable for anesthesia in surgeries and postoperative analgesia.

Description

technical field [0001] The invention relates to the technical field of medical injection, in particular to a preparation method of ropivacaine mesylate injection. Background technique [0002] Ropivacaine mesylate is an amide local anesthetic, by increasing the threshold of nerve action potential, delaying the spread of nerve impulses, reducing the speed of action potential rise, and blocking the generation and conduction of nerve impulses. Anesthesia is related to nerve fiber shaft diameter, myelination and conduction velocity. Ropivacaine mesylate injection is currently clinically mainly used for surgical anesthesia, epidural anesthesia (including cesarean section epidural anesthesia), local infiltration anesthesia; secondly for acute pain control, postoperative or Labor analgesia. Continuous epidural infusion, intermittent medication, and local infiltration anesthesia were used. [0003] In the preparation method of ropivacaine mesylate injection, the ampule bottle pac...
